Abstract
One of the common causes of the ET malfunction is NS
deviation which leads to ME pressure changes and even may lead
to secretory OM.
This study aimed at measuring tympanometric changes
before and after septal surgery in 50 patients (100 ears) with
deviated NS. Preoperative tympanometry was done for all the
patients, followed by surgical correction of the NS deformity.
Postoperative tympanometric follow up was done 2, 4 and 8 weeks
postoperatively.
Preoperative tympanometry showed that 20 ears had
negative pressure changes, while 5 ears had secretory OM.
Postoperative tympanometry showed marked improvement in 15
ears, moderate improvement in 3 ears and slight improvement in
2 ears, while ears with secretory OM showed no improvement and
they are subjected to myringotomy and insertion of ventilation
tubes.
The main objective of functional septal surgery is to cure
the patient’s subjective sensation of obstruction.
