ObjectiveProlonged intubation often leads to laryngeal injuries such as subglottic stenosis (SGS), especially in neonates with prematurity and congenital defects key for tissue healing. Recognizing at risk patients in the neonatal intensive care unit (NICU) is not well studied. The study's goals were to determine intubation risk factors, characterize laryngeal injuries, and calculate the incidence of intervention.Study DesignRetrospective case review.SettingQuaternary pediatric referral center.MethodsThis retrospective study included all intubated patients in the NICU from April 1, 2020 to 2023. Electronic records were reviewed for demographics and intubation details. Patients were categorized to into intubation only or intervention groups, including direct laryngoscopy and bronchoscopy (DLB) and tracheostomy history.ResultsA total of 441 patients were identified with 94 (21%) neonates undergoing DLB. Characteristics impacting intervention included older gestational age, genetic syndromes, and congenital heart disease. Significant risk factors were older age at first intubation, recurrent intubation events, longer intubation duration, and larger endotracheal tube (ETT) diameter, but not birth weight or intubation attempts. Otolaryngology was more likely to intubate the intervention cohort. SGS overall incidence was 2.95% with balloon dilation in 6.4%. Two-thirds of neonates with DLB ultimately required tracheostomy, in which all variables remained significant risk factors except for gestational age.ConclusionOlder age at first intubation, more intubation events, longer intubation duration, and larger ETT increased risk for future DLB and tracheostomy but not birth weight or number of intubation attempts. Most NICU patients selected for DLB ultimately required further procedures.

BACKGROUND:Current assessment techniques for determining whether a patient has normal interarytenoid anatomy, a deep interarytenoid notch, or a minor laryngeal cleft are highly variable. However, differentiating between these three entities is important, given it may distinguish whether a patient should be considered for surgical intervention. The Interarytenoid Assessment Protocol (IAAP) was developed to provide standardization of interarytenoid anatomy evaluations. We aimed to assess the reliability of the IAAP for assessment of interaytenoid mucosal height (IAMH) through a multi-institutional validation study. METHODS:Reliability of the IAAP was assessed by 10 pediatric otolaryngologists all from different academic centers. 30 de-identified endoscopic videos of interarytenoid assessments were rated at two separate time points, 2 months apart. Intra-class correlation (ICC) coefficients with two-way models were used to evaluate inter- and intra-rater reliability. RESULTS:Thirty endoscopic videos were collected for patients with a median (IQR) age of 4.9 years (59 months; range: 1 month to 20 years). On the first video assessment, inter-rater reliability was 0.74 (95% CI 0.63-0.84), and on the second video assessment, inter-rater reliability was 0.75 (95% CI 0.63-0.85) indicating strong inter-rater reliability. Overall intra-rater test-retest reliability was 0.75 (95% CI 0.69-0.79) indicating strong agreement. In almost half, 14 (46.6%) raters chose IAAP classification levels within 1 level of each other. CONCLUSIONS:Multi-institutional validation of the IAAP demonstrates strong inter- and intra-rater reliability for assessment of IAMH when evaluated through pictorial analysis. Standardization of anatomical evaluations may improve our ability to perform more reliable outcomes studies of pediatric pharyngeal dysphagia in the future.

Introduction Cervicofacial lymphatic malformations (cf-LM) may be identified on prenatal ultrasound, prompting consideration of ex utero intrapartum treatment (EXIT) to secure the fetal airway. Furthermore, the recent shift in postnatal management of cf-LM from resection alone toward a multimodal approach including sirolimus and sclerotherapy may impact the neonatal outcomes of cf-LM. This study aims to characterize the neonatal outcomes of patients with prenatally diagnosed cf-LM who underwent EXIT-to-airway. Methods Retrospective, single-center review of all patients who underwent EXIT-to-airway for cf-LM (2011-2020) was performed. Demographics, prenatal imaging, intraoperative details, and outcomes were analyzed using descriptive statistics (median [interquartile range]). Results Six patients with prenatally diagnosed cf-LM underwent EXIT-to-airway at a median gestational age of 36 (33.8-36.9) wk. The median volume on fetal magnetic resonance imaging was 187.5 mL (142.3-237.8) and median tracheoesophageal displacement index was 11 mL (9.25-15). All were successfully intubated on placental support with a median duration of 25 (15.25-91) d. There was one fatality at day of life 10 due to necrotizing enterocolitis totalis. Among survivors, 2 of 5 underwent tracheostomy placement, 4 of 5 underwent gastrostomy tubes placement, and all 5 received sirolimus at day of life of 9 [8-10] d. Four patients underwent debulking or excision of their cf-LM during the initial hospitalization. Patients had a median length of stay of 68 (45-129) d. One patient experi enced a pneumothorax with evidence of barotrauma following EXIT-to-airway requiring chest tube placement (duration 8 d). Conclusions EXIT-to-airway procedure remains a feasible strategy for mitigating neonatal hypoxia in cases of prenatally diagnosed cervicofacial lymphatic malformations. However, postnatal outcomes are variable with potential long-term aerodigestive sequelae.

Objectives The aim of this study was to determine the incidence of perioperative respiratory complications in children following tonsillectomy with cold and hot dissection surgical techniques. Study Design The study was a retrospective cohort study. Setting Retrospective chart review was performed for all children presenting for a tonsillectomy at Texas Children’s Hospital from November 2015 to December 2017. Methods Pre- and intraoperative patient factors, including surgical technique with cold or hot dissection (electrocautery or radiofrequency ablation), and perioperative anesthetic factors were collected to determine the incidence of perioperative respiratory complications. Results A total of 2437 patients underwent a tonsillectomy at Texas Children’s Hospital from November 2015 to December 2017. The incidence of perioperative respiratory complications was 20.0% (n = 487). Sickle cell disease, cardiac disease, reactive airway disease, pulmonary disease, age >2 and <3 years, and obesity, defined as a body mass index >95th percentile for age, were significant for overall perioperative respiratory complications. There was no difference in the incidence of perioperative respiratory complications in children undergoing tonsillectomy by cold or hot dissection. Conclusion Perioperative respiratory complications following tonsillectomy are more affected by patient factors than surgical technique.

Ex utero intrapartum treatment (EXIT) is utilized for safe delivery when a baby has a compromised airway. The purpose of this retrospective study was to examine the indications and outcomes of 11 children presenting with airway occluding oropharyngeal and cervical teratomas.

INTRODUCTION:Postoperative prescribing of opioids following pediatric adenotonsillectomy can have negative consequences including unnecessary opioid exposure and potential for respiratory depression. While guidelines from The American Academy of Otolaryngology/Head & Neck Surgery recommend treatment of post adenotonsillectomy pain using acetaminophen and ibuprofen, many providers continue to prescribe opioids and may do so, in part with concern for parental dissatisfaction with post-operative analgesia. Our aim was to determine whether a post-operative prescription for opioids affects parental assessment of pain control following pediatric adenotonsillectomy. METHODS:This post-operative survey assessed the parental assessment of pain control in 324 patients, ages 1-17 years undergoing adenotonsillectomy. This study was conducted at a quaternary care children's hospital in Houston, Texas from December 1, 2018 through March 31, 2019. Post-operative pain regimens included acetaminophen and ibuprofen or combination hydrocodone/acetaminophen in addition to ibuprofen for post-operative analgesia based on the attending surgeons prescribing preferences. The primary study outcome was identification of the proportion of parents rating their child's analgesia following pediatric adenotonsillectomy as poor or inadequate based on the post-operative analgesic regimen including opioids. RESULTS:Of the 798 surveys sent, the response rate was 42% (324/775) of those who received the survey email, and 69% (324/470) for those who opened the email. Between the opioid and non-opioid groups, there was no difference in gender (male; 48% vs. 51.3%; p = 0.58), race/ethnicity (white; 53% vs. 46%; p = 0.35) or insurance status (insured; 62% vs. 50.9%; p = 0.06). The proportion of parents who rated their child's pain as poor or inadequately controlled following adenotonsillectomy was relatively rare: 9% and 5% in the non-opioid and opioid groups, respectively. Parents rating their child's pain as excellent with regards to pain control following adenotonsillectomy were 58% and 50% in the non-opioids and opioid groups respectively. CONCLUSION:The results of this study indicate that non-opioid analgesic regimens following pediatric adenotonsillectomy were not associated with decreased parental satisfaction or an increasing assessment of poor or inadequately controlled pain. Limiting opioid exposure following pediatric adenotonsillectomy is feasible and does not result in worse parental satisfaction with the analgesic plan.

Objectives: Dandy-Walker malformation (DWM) is a common cerebellar malformation characterized by vermian hypoplasia with upward rotation, cystic dilatation of the fourth ventricle and elevated torcular.DWM can be diagnosed prenatally by fetal sonogram and/or magnetic resonance imaging (MRI).However, its associated neurodevelopmental abnormalities are variable and difficult to predict in prenatal counseling.We hypothesized that DWM have abnormalities beyond cerebellum and the posterior fossa, which may potentially impact neurodevelopmental variations.Methods: We retrospectively reviewed medical record and fetal MRIs of 15 fetuses with DWM.We performed post-acquisition regional volumetric fetal MRI analysis in 11 fetuses with DWM and 12 control fetuses to measure volumes of cortical plate, subcortical parenchyma, cerebellar hemispheres, and vermis.Growth trajectories between 18 and 33 weeks' gestation in each structure were modeled for each group.A logarithmic transform of the volume data was used before fitting the linear regression model.Intergroup measures were compared using ANCOVA. Results:The median (interquartile range) gestational ages of fetal MRI studies in 11 fetuses with DWM and 12 controls were 22.6 (4.3) weeks and 25.1 (9.2) weeks, respectively (p value = 0.31).

OBJECTIVE:The neurocognitive associations in paediatric obstructive sleep apnoea (OSA) are well known; however, whether polysomnographic features can predict these associations is unknown. Therefore, the primary objective of this study was to compare common polysomnographic parameters in children with OSA in the presence and absence of neurocognitive dysfunction.METHODS:Polysomnography data for children ages 3-6 years with mild-moderate OSA who as defined by AHI between 5 and 10 were analysed from a single sleep centre at a tertiary paediatric hospital from January 2016 to December 2018. The following parameters were identified: arousals per hour, percentage of time asleep, apnoea-hypopnoea index (AHI), oxygen desaturation nadir during sleeps, baseline oxygen saturation during sleep, time spent with SpO2 less than 90%, maximum transcutaneous CO2, per cent of the total sleep time spent with TcCO2 greater than 50 mmHg, age, body mass index (BMI), gender and type of disability in the neurocognitive dysfunction group. Neurocognitive diagnoses were recorded. Those with syndromic comorbidities were excluded. The study cohort was then compared to a cohort of 200 subjects with OSA and no neurocognitive disorders matched for age, gender and BMI. A paired column analysis by chi-squared analysis was then undertaken between the two groups.RESULTS:A total of 200 children were identified (126 males and 74 females) in the neurocognitive dysfunction group (OSA with neurocognitive dysfunction) and compared with 200 children in the control group (OSA without neurocognitive dysfunction) (113 males and 87 females). There were no statistical differences between groups.CONCLUSION:Commonly used polysomnographic indices are not predictive of neurocognitive dysfunction in paediatric OSA.

Objective: To describe a minimalist approach to sedating children for DISE procedures. Methods: We searched existing literature and derived and tested our algorithm on patients using evidence-based studies. Results: We were able to successfully sedate, without airway intervention, 15 highly complex children with a variety of comorbidities for DISE procedures. Conclusion: We describe a minimalistic sedation approach for DISE procedures in highly complex children. Further studies are required to compare this regimen to natural sleep states.

In patients with Pierre Robin sequence (PRS), understanding the mechanism of airway obstruction and the potential for concurrent airway lesions is important for determining appropriate intervention. When concomitant airway anomalies are present with PRS, mandibular distraction osteogenesis alone is often contraindicated and unsuccessful at alleviating the obstruction, mandating the need for tracheostomy. Herein, the authors present the second-reported case of PRS with concomitant complete tracheal rings and highlight the importance collaborative surgical efforts to avoid tracheostomy. Our patient was born with signs and symptoms of PRS and concomitant complete tracheal rings. At birth, he developed respiratory compromise that was resistant to invasive and noninvasive intervention and was transferred to our care. The severity of his airway compromise necessitated operative intervention. Due to the patient's complex medical condition, avoiding the long-term sequelae of a tracheostomy and performing mandibular distraction was favorable. However, due to his multi-level airway disease, a 2-staged approach was planned: sliding tracheoplasty to release the tracheal rings, followed by mandibular distraction to correct the micrognathia. The patient tolerated both procedures and was successfully distracted and eventually weaned into room air. When managing patients with PRS in the setting of severe respiratory distress, securing the airway and carefully evaluating for concomitant airway anomalies is crucial. Even in the setting of multi-level airway disease where mandibular distraction is typically contraindicated, by directly addressing each anatomic level of airway obstruction, the airway can be safely secured and the resultant consequences of tracheostomy can be avoided. Careful planning with a multidisciplinary team is essential.

OBJECTIVES:To determine the agreement of paediatric otolaryngologists on classifying laryngomalacia (LM).DESIGN:Intra- and interobserver agreement study of two classification systems.SETTING:Three tertiary referral paediatric centres.PARTICIPANTS:Three paediatric otolaryngologists, who were blinded to any clinical details, interpreted the videos of children diagnosed with LM using the Holinger and Olney classifications independently. They rated the videos twice with a washout period of at least 2 weeks.THE MAIN OUTCOME MEASURES:Inter- and intra-observer agreement measured by overall Fleiss kappa and unweighted Cohen's kappa coefficients. The secondary outcome measures were inter- and intra-observer agreement on the individual anatomical subunits of the supraglottis affected by LM, characterised by the subcategories of the classifications.RESULTS:Video records of infants and children <18 years who had an endoscopic diagnosis of LM from 2012 to 2017 were retrospectively chosen for inclusion (n = 73). The overall Fleiss kappa coefficient was 0.25 (95% CI 0.18-0.32) amongst the raters using the Holinger classification and 0.31 (95% CI 0.21-0.42) for the Olney classification. Intra-observer agreement using the Holinger classification was 0.30 (95% CI 0.18-0.42), 0.62 (95% CI 0.23-0.85) and 0.84 (95% CI 0.75-0.94], whilst the Olney classification yielded values of 0.41 (95% CI 0.26-0.56), 0.51 (95% CI 0.29-0.63) and 0.63 (95% CI 0.48-0.78).CONCLUSIONS:The agreement on types of LM between expert observers is modest using the Holinger and Olney classifications. This has significant implications for accurately diagnosing LM and exposes potential obstacles against credible pooling of data and extrapolation of information.

Pediatric obstructive sleep apnea presents in up to 7% of children and represents a constellation from nasal turbulence to cessation in gas exchange. There are numerous end organ sequelae including neurocognitive morbidity associated with persistent OSA. Adenotonsillectomy (AT), the first line therapy for pediatric OSA, has not been demonstrated to reduce all end organ morbidity, specifically neurological and behavioral morbidity. Furthermore, certain at-risk populations are at higher risk from neurocognitive morbidity. Precise knowledge and perioperative planning is required to ensure optimal evidence-based practices in children with OSA. This comprehensive review covers the seminal perioperative implications of OSA, including preoperative poly-somnography, pharmacotherapeutics, and postoperative risk stratification.

Objectives/HypothesisCreate a competency‐based assessment tool for pediatric tracheotomy.Study DesignBlinded, modified, Delphi consensus process.MethodsUsing the REDCap database, a list of 31 potential items was circulated to 65 expert surgeons who perform pediatric tracheotomy. In the first round, items were rated as “keep” or “remove,” and comments were incorporated. In the second round, experts were asked to rate the importance of each item on a seven‐point Likert scale. Consensus criteria were determined a priori with a goal of 7 to 25 final items.ResultsThe first round achieved a response rate of 39/65 (60.0%), and returned questionnaires were 99.5% complete. All items were rated as “keep,” and 137 comments were incorporated. In the second round, 30 task‐specific and seven previously validated global rating items were distributed, and the response rate was 44/65 (67.7%), with returned questionnaires being 99.3% complete. Of the Task‐Specific Items, 13 reached consensus, 10 were near consensus, and 7 did not achieve consensus. For the 7 previously validated global rating items, 5 reached consensus and two were near consensus.ConclusionsIt is feasible to reach consensus on the important steps involved in pediatric tracheotomy using a modified Delphi consensus process. These items can now be considered to create a competency‐based assessment tool for pediatric tracheotomy. Such a tool will hopefully allow trainees to focus on the important aspects of this procedure and help teaching programs standardize how they evaluate trainees during this procedure.Level of Evidence5 Laryngoscope, 130:2700–2707, 2020

Ex utero intrapartum treatment (EXIT) to airway has been described as a safe method to secure challenging fetal airways while on placental support. Herein, we present a unique case of a monochorionic-diamniotic twin pregnancy where both fetuses presented with oropharyngeal tumors requiring airway securement on placental bypass. A multidisciplinary tabletop simulation was convened to allow for personnel coordination between multiple services, OR equipment allocation, and preparation for a range of possible clinical scenarios. A tabletop simulation was chosen for planning since this is a simulation methodology commonly used for preparation in acute, high intensity multidisciplinary situations such as disaster preparation, and allows for exploration of multiple potential scenarios when outcomes are uncertain. The twins were urgently delivered for decreased fetal movement and decelerations in Twin B at 28 weeks 6 days. Twin A was delivered via EXIT to airway while Twin B had debulking of the tumor on placental support, with subsequent airway securement through a tracheostomy. In conclusion, for complex fetal procedures, detailed pre-operative planning with tabletop simulation may be a useful tool in achieving successful patient outcomes.

Background: Eosinophilic esophagitis (EoE) is an allergic disease characterized by marked eosinophilic infiltration and inflammation of the esophagus eventually leading to esophageal dysfunction. This condition at times may involve the airway leading to breathing difficulties. Objective: To compare the course of EoE in patients with or without airway involvement. Methods: A retrospective chart review was done on patients with a diagnosis of Eosinophilic Esophagitis and that were managed in our Aerodigestive clinic from 2012 to 2018. A total of 121 EoE patients were included in the study. Each patient's disease course was examined for pertinent information including - but not limited to - age at presentation, allergies, endoscopic and pathology results, treatments prescribed, and time to resolution. The data was analyzed for any differences between the airway and non-airway groups for each of these variables. Results: The variables that were analyzed showed no significant difference between patients suffering from EoE with (n = 19) and without (n = 102) airway involvement. However, patients with airway disease trended towards being younger in age at presentation as compared to those without airway symptoms (6.68 years vs. 9.69 years, p = 0.69). Analysis of endoscopic and pathology findings revealed no difference. Similarly, no differences were found between the prescribed treatments. Kaplan-Meier estimates of time to disease remission indicated that 50% of patients had resolution at one year, regardless of airway involvement (p = 0.31). Conclusions: Our findings indicate that the disease course of patients with EoE does not vary depending on the presence of airway symptoms. Thus, patients with airway symptoms should not be diagnosed or treated any different than those without airway symptoms.

INTRODUCTION:Advances in fetal imaging have allowed us to identify abnormalities previously not appreciated. With this study, we hope to identify factors predicting a difficult airway at birth and review the perinatal outcomes of these patients. METHODS:Sixteen patients with antenatally diagnosed micrognathia were reviewed from a tertiary care hospital database from 2011 to 2016. Jaw index (JI), amniotic fluid index (AFI), glossoptosis, gastric size, and oropharynx obliteration were assessed. The airway support required at birth, specialist team involvement, and outcomes were evaluated. RESULTS:Nine (56.3%) of 16 patients had JI <5th percentile, 3 (33.3%) of 9 had difficult intubation, 2 (22.2%) of 9 needed an emergency tracheostomy, and 1 (11.1%) of 9 died. Seven patients had polyhydramnios, 2 (28.6%) of 7 had difficult intubation, 2 (28.6%) of 7 required tracheostomy, and 1 (14.3%) of 7 died. Twelve patients had either JI <5th percentile or abnormal AFI, 5 (41.7%) of 12 had difficult intubation, 2 (16.7%) of 12 required tracheostomy, and 1 (8.33%) of 12 died. For the group without otolaryngology consultation, 8 (50%) of 16, 1 (12.5%) of 8 had difficult intubation and 1 (12.5%) of 8 died because airway was not secured after 45 minutes of resuscitation. CONCLUSION:Jaw index <5th percentile or abnormal AFI predicts a difficult airway. A multidisciplinary approach with otolaryngology involvement for airway intervention may be required at birth.

OBJECTIVES:The aim of this study was to evaluate single-stage laryngotracheal reconstruction (ssLTR) outcomes before and after the implementation of a postoperative care protocol in pediatric patients.METHODS:A case-control study with chart review was conducted at 2 tertiary academic centers from 2010 to 2016. Pediatric patients who underwent ssLTR with a postoperative care protocol were compared with those who did not receive care under this protocol. Data regarding perioperative management were collected and compared using χ2 and Wilcoxon rank tests. Planned extubation, length of intubation in the intensive care unit, and complications were examined.RESULTS:Nineteen patients completed ssLTR after the protocol was initiated, and 26 prior patients were used as control subjects. Planned extubation failed in 9 patients (35%) in the control group compared with 1 patient (5%) in the protocol group (P < .05). Using a structured protocol demonstrated a decrease in delayed extubation and intensive care unit stay (P < .05). Despite more postprotocol patients' requiring posterior graft placement, preprotocol patients were less likely to be extubated within 7 days (P < .05).CONCLUSIONS:The authors propose an intensive care unit protocol that uses a combination of pharmacologic agents to optimally reduce the risk for adverse events that delay time to extubation and thus decannulation. Timely extubation was more likely with the use of this postoperative care protocol using a multidisciplinary approach involving otolaryngologists, pharmacists, intensivists, and anesthesiologists.

Background The ex utero intrapartum treatment (EXIT) is utilized to transition fetuses with prenatally diagnosed airway obstruction to postnatal life. We describe the unique clinical course, diagnosis, treatment, and outcomes of patients with cervical lymphatic malformation (CLM) managed with EXIT. Methods Review of fetuses with diagnosed CLM was delivered by EXIT (2001-2018) in a tertiary referral fetal center. Outcomes included survival, tracheostomy at discharge, neonatal course after delivery, and pulmonary hypoplasia. Data are reported as median [range] and rate (%). Results Out of 45 patients delivered by EXIT, 10 were delivered for CLM: seven had polyhydramnios, one had nonimmune hydrops, five delivered preterm, and three were emergency EXITs. The EXIT time and estimated blood loss were 125 minutes (95, 158) and 900 mL (500, 1500), respectively. Airway was secured in all. There was one neonatal death (day 8) with prematurity, sepsis, and pulmonary hypoplasia. Three out of nine were discharged with a tracheostomy. Conclusion In CLM, close monitoring for structural neck involvement and development of polyhydramnios are important and may be an indication for EXIT as the optimal delivery mode. An experienced multidisciplinary team is a key factor for an effective approach to the obstructed airway in CLM.
