Abstract

Chronic otitis media is defined as the chronic inflammation of the mucoperiosteal lining lining of the middle ear cleft which presents with recurrent ear discharge through tympanic membrane perforation. The study was planned to evaluate the patency of the aditus ad antrum in cases of chronic otitis media mucosal type, and its correlation with various direct and indirect indicators of blocked aditus. The prospective longitudinal study was conducted on 100 patients with chronic otitis media mucosal type. The commonest complaint of patients was ear discharge (100%) followed by hearing impairment in 72% patients.Tympanoplasty with antrotomy was performed. The patency and dimensions of the aditus ad antrum were assessed by saline water test. In 41% cases saline test showed blockade, on further drilling patency achieved in 27 cases with minimal drilling and dissection of mucosa with or without fibrotic mucosal bands. In rest 14 cases widening of aditus and atticotomy was required to achieve patency. Out of these nine were having associated tympanosclerosis and five were having edematous mucosa. Ossicular necrosis was seen on 18 cases. Presence of myringosclerosis and polypoidal edematous mucosa increases the probability of an obstructed aditus ad antrum. Mastoid antrostomy and water test for patency can be performed without additional cost and risk to the patient in minimal time and can be considered as the surest indicator of patency of aditus ad antrum.
