Abstract
Otitis media with effusion (OME) is the most common cause of acquired pediatric hearing loss. The treatment of persistent OME includes myringotomy with or without tube insertion, with a reported recurrence rate of 19.9-40%. This study aims to investigate the recurrence rate of OME and its predictors following myringotomy. A retrospective study that included 345 ears that underwent myringotomy for persistent OME in 179 pediatric patients during 2016-2018. Patients were followed for 36-48 months post myringotomy procedure to detect the recurrence rate. The study sample was divided into two groups based on recurrence status, and the groups were compared using chi-square test and independent T-test. Significant variables (p-value <= 0.05) were included in the logistic regression model to determine the predictors of OME recurrence after myringotomy. OME recurrence was detected in 85 ears (24.64%). The OME recurrence rate is higher in patients who underwent myringotomy alone compared to myringotomy with tube insertion (44.1% vs. 22.8%). The insertion of a tympanostomy tube decreases the recurrence rate of OME by 59.9% (OR 0.401; 95% CI 0.162-0.933). The other socio-demographic and clinical characteristics such as age, siblings, daycare attendance, passive smoking, previous acute otitis media, atopy, and adenoidectomy did not significantly influence OME recurrence (p-value > 0.05). The recurrence rate of OME following myringotomy is high. Myringotomy with tube insertion significantly decreases the recurrence rate and the need for further surgeries compared to myringotomy alone. Adenoidectomy and the patient's age have no impact on the recurrence rate of OME.
