Total Annulus Excision Tympanoplasty-A Solution to Recurrent Myringitis: Double Blind Randomized Trial
Journal of laryngology and otology/The journal of laryngology & otology(2021)
摘要
OBJECTIVE:In spite of continuous refinements in tympanoplasty techniques, results are variable, and it is not uncommon to see a discharging eardrum even after a good graft uptake. This study aimed to evaluate the efficacy of total annulus excision tympanoplasty in comparison with conventional underlay tympanoplasty.METHOD:This was a double blinded, randomised, controlled trial performed at a tertiary care centre. After inclusion and exclusion criteria were met, 56 patients were enrolled and randomised, and 28 patients were allocated to each group (group A (conventional tympanoplasty) and group B (total annulus excision)). Patients and evaluators were blind to the procedure performed.RESULTS:Patients in group B (total annulus excision) showed better graft uptake and no discharge with better gains in air conduction thresholds (p < 0.05) when compared with group A (conventional tympanoplasty).CONCLUSION:In view of the advantages it offers, total annulus excision tympanoplasty may be preferred over the conventional techniques in patients with central perforations.
