RESUMO
Otitis media with effusion (OME) is amongst the most common pediatric diseases and the most common cause of hearing loss in children. It is accepted that adenoid hypertrophy (AH) is related to OME incidence. Better understanding of the correlation between the relative size of AH and the incidence of persistent OME may provide evidence to support a more standardized approach to the diagnosis and treatment of OME. A retrospective study carried out between April 2016 and April 2018 collected data on 65 children aged 2-12 years, diagnosed with chronic OME and symptoms of AH, where conservative therapy failed. Pre-diagnostic data were collected from patient history, otoscopy, rhinoscopy, and oropharyngoscopy findings. Diagnostic workup included tympanometry, audiometry, and flexible nasal fiberoptic endoscopy. Adenoid grading was performed according to Cassano method after endoscopic visualization. Of the 65 patients, 37 were male and 28 were female. There was no statistically significant difference according to gender or average age. The highest incidence of persistent OME with AH was recorded in the youngest age groups (2-5 and 6-9 years). The most frequent AH grades were grade II (35.38%) and grade III (50.77%), yielding a statistically significant result. The most common presenting symptoms were hearing impairment, snoring, and nasal obstruction (100%, 64.62% and 60%, respectively). Higher AH grades are critical for persistence of OME and may cause conservative therapy failure.
