OBJECTIVE:To compare the efficacy of the Modified Frailty Index and Modified Surgical Apgar scores in predicting postoperative outcomes in head and neck cancer patients. METHODS:We retrospectively reviewed patients who underwent major head and neck surgery between 2012 and 2015. Modified Surgical Apgar, and Frailty Index, scores were calculated on 723 patients. The primary outcome was 30-day complication and/or mortality. RESULTS:The mean Modified Frailty Index was 0.11 ± 0.12, and mean Modified Surgical Apgar score was 6.15 ± 1.67. Both scores were significantly associated with 30-day complication (P<0.05). The Modified Surgical Apgar score was superior to the Modified Frailty Index in predicting complications (Area Under the Curve (AUC) = 0.76; 95 % Confidence Interval (CI), 0.722-0.793; and AUC=0.59; 95 % CI, 0.548-0.633, respectively). Concurrent use of both scoring systems (AUC=0.77) was not superior to individual use. An increase in the mFI from 0.27 to 0.36 was associated with an increase in the risk of complication postoperatively (Odds Ratio (OR) = 3.67; 95 % CI, 1.30-10.34, P=.014). A reduction in the mSAS from 7 to 6 increased the risk of complication following surgery (OR=2.64; 95 % CI, 1.45-4.80; P=.002). CONCLUSION:Both scores are useful in risk stratifying head and neck cancer patients. The Modified Surgical Apgar score was superior at predicting complications; concurrent use of both scores added minimal benefit.

PURPOSE OF REVIEW:This review highlights recent advances in facial reanimation surgery particularly related to muscle transposition and free functional muscle transfer (FFMT). RECENT FINDINGS:FFMT and muscle transposition are mainstays in the treatment of chronic facial paralysis. Recent literature evaluates single versus dual innervated FFMT, reanimation of the periocular region and lower lip depressors, and indications for such methods over gold standard FFMT techniques. New donor sites for muscle transposition and FFMT are also described. SUMMARY:Gracilis FFMT (GFMT) continues to be the gold standard in dynamic facial reanimation for patients with chronic facial paralysis. Muscle transposition should be considered in older patients, those medically unfit for long operative procedures, and individuals who prefer more immediate results. With respect to FFMT, described nerve coaptation patterns, surgical stages, and donor muscle choice vary. Standardization of data reporting and outcome measures is needed in future studies.

BACKGROUND:This study compares the outcomes of osteocutaneous radial forearm free flap (OC-RFFF) and fibula free flap (FFF) reconstruction of mandibular osteoradionecrosis (ORN). METHODS:Retrospective review of patients undergoing OC-RFFF/FFF reconstruction for mandible ORN between 2005 and 2020 at a tertiary center. Patient characteristics, postoperative complications, and functional outcomes were evaluated using chi-squared and logistic regression analysis. RESULTS:Fifty-six patients were included (OC-RFFF: 38; FFF: 18). Significantly more OC-RFFF patients had lateral mandible defects (94% vs. 61%, p = 0.0014). There were significantly more patients with exposed intraoral bone in the OC-RFFF group (23% vs. 0% p = 0.02), but no significant differences in hardware complications or flap failure. Donor site partial skin graft loss was more common in the FFF group (22% vs. 2.6%, p = 0.016), but no other significant differences in donor site morbidity were seen. Bivariable analysis showed no impact of flap type, tobacco/alcohol use, diabetes, or hypothyroidism on postoperative complications. Sixty percent of OC-RFFF, and 67% of FFF, patients resumed an oral diet after surgery. Oral diet was not impacted by flap type (OR = 0.769, 95% CI = 0.201-2.706, p = 0.688). CONCLUSION:The OC-RFFF is an acceptable option in the reconstruction of ORN involving the lateral mandible, though there is increased risk of bone exposure. These findings can help guide surgeon selection of microvascular free flap donor sites and appropriate patient counseling.

The National Comprehensive Cancer Network (NCCN) guideline recommends consideration of weekly cisplatin as an alternative option for patients with head and neck cancer undergoing definitive chemoradiation. However, in a recent phase III trial (ConCERT), 20

Craniofacial fibrous dysplasia (CFFD) is a benign, bony disease that may affect the skull base.1,2 Most cases are asymptomatic and observed; however, advanced disease can present with cranial neuropathy or craniofacial deformity requiring intervention.3-5 A 16-year-old adolescent girl with known CFFD involving the sphenoid and frontal bones with severe bilateral optic canal narrowing developed progressive right eye visual decline and frontal cosmetic deformity. Visual acuity worsened oculus dextrus (OD) to 20/30 with a new superior nasal scotoma and 20% loss in the retinal nerve fiber layer and remained oculus sinister (OS) 20/20. The patient was recommended a staged subfrontal craniotomy for right optic decompression and simultaneous correction cosmetic deformity followed by endonasal right optic decompression. On postoperative day one, visual acuity OD improved to 20/20; however, she developed OS visual decline to 20/800. Curiously, there were no episodes of intraoperative hypotension or additional iatrogenic compression. Use of methylprednisolone led to improvement OS 20/400. Given persistent visual decline, urgent second stage endonasal bilateral optic nerve decompression, rather than unilateral, was performed. Postoperatively, vision improved to OS 20/200. At one month, her vision improved to OD 20/15 and OS returned to 20/20 with a paracentral scotoma and 29% decline in left retinal nerve fiber layer with further improvement anticipated. This video describes a multidisciplinary, multistaged approach in treatment of optic nerve compression due to CFFD in addition to the management of unanticipated contralateral visual decline. The patient consented to the procedure and publication of her image. No Institutional Review Board/ethics committee approval was necessary for this case report.

BACKGROUND:Oral cavity squamous cell carcinoma (OSCC) may mimic other more common odontogenic processes such as infection, trauma, and benign pathology. Delays in diagnosis and treatment are known to result in poorer survival outcomes. PURPOSE:The study purpose was to measure the association between referral type and OSCC stage at time of presentation. STUDY DESIGN, SETTING, SAMPLE:This was a retrospective cohort study composed of newly diagnosed OSCC patients treated with surgical resection from 2014 to 2023 at Roswell Park Comprehensive Cancer Center. Patients who presented with self-referrals or had surgical treatment outside of Roswell Park Comprehensive Cancer Center were excluded. PREDICTOR VARIABLE:The primary predictor was referral source (dental vs medical specialty). MAIN OUTCOME VARIABLE:The primary outcome was pathological T stage (pT stage). The secondary outcome was overall survival (OS). COVARIATES:Covariates included demographic data and cancer-related variables (symptomatology, subsite, and risk factors). ANALYSES:A multivariate logistical regression model for pT stage was constructed using all significant covariates as well as preoperative patient and tumor characteristics. For OS, Kaplan-Meier survival curves were constructed and compared with the log-rank test. A P < .05 was considered statistically significant. RESULTS:A total of 215 subjects were included in the study sample. The majority were referred by a dental provider (n = 132, 62.3%). Dental referrals presented with significantly earlier T stage disease (RRpT3/T4 0.65, P < .01) and had lower rates of cervical nodal positivity (RRpN1-N3 0.62, P = .01). Dental referral independently increased the odds of early pT stage presentation (odds ratio 5.10, P < .01) after controlling for age, sex, oral pain symptoms, social history (smoking and drinking), head neck cancer history, and tumor subsite. Dental referrals had significantly improved OS (P = .03) and were also associated with lower rates of oral pain symptoms (RRoral pain 0.80, P = .02), lymphovascular invasion (RRLVI 0.50; P = .04), and perineural invasion (RRPNI 0.63, P = .04). CONCLUSIONS AND RELEVANCE:Among subjects with similar risk factors, those referred from dental providers were found to have earlier stage disease. Unfortunately, over half of dental referrals still presented with pain symptoms and more than a third presented with locally advanced disease. Dental providers appear to be positioned to detect earlier OSCC; however, there is room for improvement.

As the introduction of autologous free tissue transfer, microsurgical techniques for mandibular reconstruction have improved patients' functional and esthetic outcomes. Several large series have reported excellent results with various osseous free flap donor sites, establishing microvascular free tissue transfer with bone and soft tissue as the gold standard for mandibular reconstruction.1 Vascularized tissue transfer can provide an appropriate reconstruction in one step after ablative surgery, allowing for timely adjuvant radiation therapy.

Background Given the role of systematic inflammation in cancer progression, lymphocyte-monocyte ratio (LMR) from peripheral blood has been suggested as a biomarker to assess the extent of inflammation in several solid malignancies. However, the role of LMR as a prognostic factor in head and neck cancer was unclear in several meta-analyses, and there is a paucity of literature including patients in North America. We performed an observational cohort study to evaluate the association of LMR with survival outcomes in North American patients with head and neck cancer. Methods A single-institution, retrospective database was queried for patients with non-metastatic head and neck cancer who underwent definitive chemoradiation from June 2007 to April 2021 at the Roswell Park Comprehensive Cancer Center. Primary endpoints were overall survival (OS) and cancer-specific survival (CSS). The association of LMR with OS and CSS was examined using nonlinear Cox proportional hazard model using restricted cubic splines (RCS). Cox multivariable analysis (MVA) and Kaplan–Meier method were used to analyze OS and CSS. Pre-radiation LMR was then stratified into high and low based on its median value. Propensity scored matching was used to reduce the selection bias. Results A total of 476 patients met our criteria. Median follow up was 45.3 months (interquartile range 22.8–74.0). The nonlinear Cox regression model showed that low LMR was associated with worse OS and CSS in a continuous fashion without plateau for both OS and CSS. On Cox MVA, higher LMR as a continuous variable was associated with improved OS (adjusted hazard ratio [aHR] 0,90, 95% confidence interval [CI] 0.82–0.99, p = 0.03) and CSS (aHR 0.83, 95% CI 0.72–0.95, p = 0.009). The median value of LMR was 3.8. After propensity score matching, a total of 186 pairs were matched. Lower LMR than 3.8 remained to be associated with worse OS (HR 1.59, 95% CI 1.12–2.26, p = 0.009) and CSS (HR 1.68, 95% CI 1.08–2.63, p = 0.02). Conclusion Low LMR, both as a continuous variable and dichotomized variable, was associated with worse OS and CSS. Further studies would be warranted to evaluate the role of such prognostic marker to tailor interventions.

Immediate reconstruction and dental rehabilitation for ablative defects of the head and neck in one surgery is now a commonly used technique among reconstructive surgeons. Often patients are edentulous or partially edentulous in the jaw opposing that with pathology. In this case, only rehabilitating the dental arch affected by pathology would not render the patient with a functional occlusion. We introduce the "super reconstruction" concept which includes not only rehabilitating the dental arch affected by pathology but also the opposing arch, giving the patient a fully functional occlusion at the time of ablative surgery. This concept is described through a case of a patient with a T4aN0M0 squamous cell carcinoma of the maxilla who underwent total maxillectomy, immediate fibula flap reconstruction of the maxilla with, and full arch dental implant placement into the maxilla and opposing mandible with prosthetic rehabilitation.

Key Points Question What is the association of overweight and obese body mass index (BMI) with posttreatment response, tumor recurrence, and survival outcomes among patients with head and neck cancer who underwent chemoradiotherapy? Findings In this cohort study involving 445 patients, both overweight and obese BMI were associated with complete metabolic response after chemoradiotherapy. Only overweight BMI was associated with improved overall survival, progression-free survival, and reduction in locoregional failure. Meaning This study suggests that overweight BMI is an independent factor favorably associated with complete metabolic response after chemoradiotherapy, survival, and locoregional failure.

ImportanceAfter 10 pack-years of smoking was initially established as a threshold for risk stratification, subsequent clinical trials incorporated it to identify candidates for treatment deintensification. However, several recent studies were unable to validate this threshold externally, and the threshold for smoking exposure remains unclear.ObjectiveTo estimate the threshold of pack-years of smoking associated with survival and tumor recurrence among patients with head and neck cancer.Design, Setting, and ParticipantsThis single-institution, cohort study included patients with nonmetastatic head and neck cancer receiving chemoradiation from January 2005 to April 2021. Data were analyzed from January to April 2022.ExposuresHeavy vs light smoking using 22 pack-years as a threshold based on maximizing log-rank test statistic.Main Outcomes and MeasuresOverall survival (OS), progression-free survival (PFS), locoregional failure (LRF), and distant failure (DF).ResultsA total of 518 patients (427 male [82.4%]; median [IQR] age, 61 [55-66] years) were included. Median (IQR) follow-up was 44.1 (22.3-72.8) months. A nonlinear Cox regression model using restricted cubic splines showed continuous worsening of OS and PFS outcomes as pack-years of smoking increased. The threshold of pack-years to estimate OS and PFS was 22. Cox multivariable analysis (MVA) showed that more than 22 pack-years was associated with worse OS (adjusted hazard ratio [aHR] 1.57; 95% CI, 1.11-2.22; P = .01) and PFS (aHR, 1.38; 95% CI, 1.00-1.89; P = .048). On Fine-Gray MVA, heavy smokers were associated with DF (aHR, 1.71; 95% CI, 1.02-2.88; P = .04), but not LRF (aHR, 1.07; 95% CI, 0.61-1.87; P = .82). When 10 pack-years of smoking were used as a threshold, there was no association for OS (aHR, 1.23; 95% CI, 0.83-1.81; P = .30), PFS (aHR, 1.11; 95% CI, 0.78-1.57; P = .56), LRF (aHR, 1.19; 95% CI, 0.64-2.21; P = .58), and DF (aHR, 1.45; 95% CI, 0.82-2.56; P = .20). Current smoking was associated with worse OS and PFS only among human papillomavirus (HPV)-positive tumors (OS: aHR, 2.81; 95% CI, 1.26-6.29; P = .01; PFS: aHR, 2.51; 95% CI, 1.22-5.14; P = .01).Conclusions and RelevanceIn this cohort study of patients treated with definitive chemoradiation, 22 pack-years of smoking was associated with survival and distant metastasis outcomes. Current smoking status was associated with adverse outcomes only among patients with HPV-associated head and neck cancer.

Objectives: We sought to define the optimal threshold for anemia in North American head and neck cancer patients and evaluate its role as a prognostic biomarker. Materials and Methods: A single-institution database was queried for patients with head and neck cancer who underwent chemoradiation from January 2005 to April 2021. An optimal threshold of hemoglobin (Hgb) level was defined based on maximum log-rank test statistic. Cox multivariable analysis (MVA), Kaplan-Meier, and propensity score matching were performed to evaluate treatment outcomes. Results: A total of 496 patients were identified. Threshold for Hgb was determined to be 11.4 for both overall survival (OS) and progression-free survival (PFS). Low Hgb was associated with worse OS (adjusted hazards ratio [aHR] 2.41, 95 % confidence interval [CI] 1.53-3.80, p < 0.001) and PFS (aHR 2.01, 95 % CI 1.30-3.11, p = 0.002). Similar findings were observed among 39 matched pairs for OS (5 year OS 22.3 % vs 49.0 %; HR 2.22, 95 % CI 1.23-4.03, p = 0.008) and PFS (5-year PFS 24.3 % vs 39.1 %; HR 1.78, 95 % CI 1.02-3.12, p = 0.04). Among those with HPV-negative tumors, low Hgb was associated with worse OS (aHR 13.90, 95 % CI 4.66-41.44, p < 0.001) and PFS (aHR 5.24, 95 % CI 2.09-13.18, p < 0.001). However, among those with HPV-positive tumors, low Hgb was not associated with both OS (aHR 1.75, 95 % CI 0.60-5.09, p = 0.31) and PFS (aHR 1.13, 95 % CI 0.41-3.14, p = 0.82). Conclusion and relevance: Low Hgb below 11.4 was an independent adverse prognostic factor for worse survival. It was also prognostic among patients with HPV-negative tumors, but not for HPV-positive tumors.

Flexible nasopharyngoscopy (FNP) is a specialized skill commonly used by otolaryngologists as an important component of the head and neck examination. FNP can be diagnostic and therapeutic for many head and neck pathologies. Mastering this skill facilitates the effective performance of other specialized skills and procedures such as fibreoptic nasal intubations and flexible bronchoscopies. During otolaryngology rotations and electives, medical students are exposed to a high volume of FNP. Often, they are also asked to perform this procedure in clinic and on-call. There is currently no widely available simulation tool for medical students to practice using FNP, and medical students at our institution do not receive any formal training prior to performing FNP. The following is an introductory guide for medical students to become proficient at performing FNP while on their otolaryngology rotation.

Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) is the causative agent of COVID-19 which was detected in late 2019 in Wuhan, China. As of September 2022, there have been over 612 million confirmed cases of COVID-19 with over 6.5 million associated deaths. In many cases, anosmia and dysgeusia have been identified as primary symptoms of COVID-19 infection in patients. While the loss of smell (anosmia) and loss of taste (dysgeusia) due to COVID-19 infection is transient in most patients, many report that these symptoms persist following recovery. Understanding the pathogenesis of these symptoms is paramount to early treatment of the infection. We conducted a literature review of Google Scholar and PubMed to find and analyze studies discussing anosmia and dysgeusia in the context of COVID-19 to understand the progression and management of these symptoms. The mechanism for dysgeusia is largely unknown; however, pathogenesis of anosmia includes inflammation and cytokine release resulting from the infection that alters neuronal signaling, thus inducing the loss of smell that patients experience. Anosmia may be managed and potentially resolved sooner with a combination therapy of olfactory training and budesonide irrigation of the nasal cavity. It is important to note that the variants of SARS-CoV-2 are genetically distinguished from the original virion due to a mutation in their spike proteins, giving them a different symptom profile regarding anosmia and dysgeusia. This variability in symptomatology is an area of study that needs to be further explored.

Background Transoral laser microsurgery is widely used for treating T1/T2 glottic cancers. Hyaluronic acid (HA) is commonly used in vocal cord augmentation. We investigated the impact of intra-operative injection laryngoplasty on voice outcomes in early glottic cancer. Methods Twenty patients were randomized to the treatment group receiving HA injection to the vocal cord contralateral to the lesion; or the control group, receiving no injection. Patients had a Voice Handicap Index-10 (VHI-10) questionnaire and a Maximum Phonation Time (MPT) measurement preoperatively and at 3, 12 and 24 months post-operatively. Mean change in VHI-10 and MPT, compared to baseline and between time points, were compared. Survival estimates were calculated. Results Mean VHI-10 scores improved over time amongst all patients. There were no changes in mean VHI-10 from pre-operative values to 3, 12 or 24 months post-operatively. There were no significant differences when comparing various timepoints between groups. There were no significant changes in MPT amongst the groups, or the time-points compared. Two-year overall survival was 91.7%; disease free survival was 80.9%; no difference in recurrence free survival was seen between the groups. Conclusion Subjective voice scores improved over time in both groups; there were no improvements in VHI-10 or MPT scores in the injection group, over control, at any time points. We saw no significant impact for intra-operative HA injection laryngoplasty on subjective or objective voice outcomes following surgery for early glottic cancers. Graphical abstract

Background Distant metastasis in thyroid cancer significantly reduces survival in patients with well-differentiated thyroid carcinoma (WDTC). There is limited information available to clinicians regarding pathological features that confer a higher risk of distant metastasis (DM). This study aimed to identify patient and tumor factors that were associated with the development of DM over time in patients with WDTC. Methods A retrospective cohort analysis of patients with WDTC ( n = 584 ) at our institution was performed between 2007 and 2017. A total of 39 patients with DM and 529 patients with no DM (NDM) were included. Patient demographics, tumor characteristics and patient survival were compared between the DM and NDM groups using a univariate analysis. Multivariate Cox-proportional hazards model was used to evaluate the risk of developing distant metastasis over time. Kaplan-Meier analysis was used to compare survival between the DM and NDM groups. Results Distant metastasis had a substantial impact on disease-specific survival (DSS) at 5 and 10-years in the DM group; 71.0% (SE 8.4%) and 46.9% (SE 11.6%) respectively, compared to 100% survival in the NDM group ( p < 0.001). The DM group had significantly higher proportions of males, lymphovascular invasion (LVI), nodal metastasis (NM), large tumor size (TS), extrathyroidal extension (ETE), positive resection margins, multifocality, follicular thyroid cancer (FTC), tall cell variant of papillary thyroid cancer (PTC), and Hurthle cell carcinoma (HCC), when compared to the NDM group ( p < 0.05 ). A TS ≥ 2 cm (Hazard Ratio (HR) 1.370), NM (HR 3.806) and FTC (HR 7.068) were associated with a significantly increased hazard of developing distant metastasis in patients with WDTC. Conclusions TS ≥ 2 cm, NM and FTC are associated with a significantly increased propensity for developing DM in our cohort of WDTC patients. Graphical abstract

Laryngeal secondary malignancies are rare, and most spread locoregionally from hypopharyngeal or thyroid primaries. Metastasis of ovarian carcinoma to the larynx is extremely rare. A 65-year-old woman with a history of high grade serous ovarian carcinoma was undergoing carboplatin chemotherapy for recurrence. She presented with progressive dysphagia and hoarseness; a computer tomography (CT) scan demonstrated bilateral necrotic lymphadenopathy and hypopharyngeal fullness. A hypopharyngeal mass was confirmed on examination, and operative biopsy identified it as high-grade serous ovarian. To our knowledge, this report describes the second immunohistochemically proven metastatic ovarian cancer detected in the larynx in the world literature.

Caustic ingestions can severely injure the upper and lower aerodigestive tract, resulting in detrimental mucosal changes both acutely and chronically. Injuries are most severe following alkaline ingestion. Esophagectomy is often recommended in patients with high-grade esophageal injuries to mitigate the risk of perforation. Esophageal reconstruction after these injuries is often delayed, and staged, allowing adequate tissue stabilization before further manipulation. Here, we report on a 25 year-old woman who presented with a high-grade caustic esophageal injury following the ingestion of an alkaline drain cleaner. She underwent an emergent thoracic esophagectomy, gastrectomy and a cervical salivary esophagostomy. Post-operatively, she developed supraglottic and hypopharyngeal strictures, but maintained a functional larynx. She subsequently underwent a staged, extrathoracic total esophageal reconstruction using an anterolateral thigh (ALT) myocutaneous free flap with laryngeal preservation. Although serial esophageal dilatations and trans-oral laser procedures for pharyngeal strictures were required, she was able to maintain the ability to swallow.

Introduction. Pulsatile tinnitus is a relatively common presentation in otolaryngology clinics, most cases of which have a treatable cause. This presentation warrants a thorough workup to identify treatable, and rule out life-threatening, etiologies. We present a case of a patient with pulsatile tinnitus arising from multiple dilated venous channels in the head and neck.Case Presentation.We present the case of a 65-year-old Caucasian female with a two-year history of progressive, bilateral pulsatile tinnitus, which had become debilitating. Computed-tomographic angiography (CTA) studies ruled out an intracranial vascular cause for her symptoms. However, computed tomography (CT) scanning and magnetic resonance imaging (MRI) revealed multiple dilated bilateral, low-flow, venous channels throughout the head and neck. The proximity of such dilated venous channels to the temporal bone provides a route for sound to be transmitted to the inner ear.Conclusion. Arterial, venous, and systemic etiologies can cause pulsatile tinnitus. Arteriovenous malformations (AVMs) of the head and neck represent less than 1% of cases. In our patient, dilated low-flow venous malformations are the likely source of her symptoms, which is the first reported case in the literature.
