Özet: Objectives: To evaluate the role of distortion product otoacoustic emissions (DPOAE) results in children with middle-ear effusion before and after ventilation tube insertion. Patients and Methods: The study was conducted between the September 2007 and May 2008 at the Otolaryngology Clinic diagnosed with middle-ear effusion. A prospective study was carried out 30 patient (18 males, 12 females; mean age 8.6 years; range 6 to 15 years) and a total of 41 ears with middle- ear effusion. A total of 30 ears of 15 volunteers healthy control group (8 males, 7 females; mean age 7.8 years; range 5 to 15) included in the study. All children listed for appropriate surgery had a pre- and postoperative (four week after) tympanometry, pure tone audiometry and DPOAE recorded. A comparison was made between control group DPOAE value and pre- and postoperative DPOAE value of patient. Results: Preoperatively, 41 ears had an abnormal tympanometry of which 80% had absent DPOAE. After four week all postoperative patients with surgery had 92.6% a normal DPOAE. Control group of 29/30 ears had a normal (96.7%) DPOAE. Conclusion: Patients with otitis media with effusion measured preoperative DPOAE, postoperative after one month all patients with grommets had a more DPOAE value comparison with preoperative, but less for control group.
