Abstract
This study anus at determining the effect of transmyringeal ventilation on Eustachian tube functions. Seventy ears clinically diagnosed as having otitis media with effusion or grade I and II retraction of pars-tensa of tympanic membrane were treated with antiallergics, decongestants, mucolytics, and antibiotics as required for maximum upto three months. In forty-five ears that showed neither symptomatic nor audiometric improvement, transmyringeal ventilation was restored by myringotomy and ventilation tube insertion. There after, Eustachian tube functions were assessed by using pressure equilibration test. The post-operative audiograms showed mean hearing gain of 16. 6 dB (S D±7.9) in majority (96%) of the ears. At first week 93% ears could not either totally or partially equilibrate positive or negative pressure. The percentage in the poor function group remained 91% even at the end of 6 months showing no significant effect of ventilation tube insertion on active ET functions.
