Abstract	OBJECTIVE: To evaluate the effect of nasal surgery on Eustachian Tube Function (ETF) and Middle Ear (ME) ventilation. STUDY DESIGN: Quasi experimental single group study. PLACE AND DURATION: Audiology Section of ENT Department of Lahore General Hospital, over a period of 1 year from 1 August 2015 to 31 July 2016. METHODOLOGY: Patients who presented with nasal obstruction and were planned for surgery were included using non probability sampling technique. Acoustic impedance test (tympanometry), with Valsalva and Toynbee Tests was performed one day preoperatively and 30 days post-operatively and results noted. In Valsalva test, the effect of high positive nasopharyngeal pressures at the proximal end of the Eustachian tube was evaluated by obtaining an experimental tympanogram, while in Toynbee test, a tympanometric peak pressure shift of >10 daPa indicated good ETF. RESULTS: Among total of 75 patients, 80% were diagnosed with type B graph whereas 20% with type C graph preoperatively, among 80% Type B graph cases, 62% improved to Type C. The remaining 38% patients with Type B and all patients of Type C graphs i.e., 20% of the total cases, improved to Type A (Normal graph), indicating significant improvement. Pearson correlation between the two variables i.e., pressure on Eustachian tube (daPa) before surgery (DaPaBS) and after surgery (DaPaAS), was significant with a value of 0.858 indicating a positive association. CONCLUSION: Nasal surgery results in improvement in Eustachian tube functions and middle ear ventilation.
