Objectives: This study aimed to determine the value of
otoacoustic emission tests in the diagnosis and treatment
of the otitis media with effusion.
Patients and Methods: Seventy-eight ears of 39 patients
(24 males, 15 females; mean age 7.84 years; range 4 to 14
years) operated on because of serous otitis media with effusion
and adenoid hypertrophy between September 2006
and May 2007 were included in the study. The medical
history, otoscopic examination and audiologic tests were
used in diagnosis. Otoacoustic emission tests (DPOAE
and TEOAE), pure tone audiometry and tympanometry
were also applied in the pre- and postoperative first month.
Myringotomy and ventilation tube insertion was performed
on patients with type B tympanograms.
Results: In patients with type B tympanograms, preand
postoperative audiogram values compared with pretreatment
air and bone gap values significantly decreased
(p<0.01). After treatment DPOAE and TEOAE positivity
compared to pretreatment values significantly increased
(p<0.001). The presence of middle ear effusion affects otoacoustic
Conclusion: The results of this study revealed that the
measurement of otoacoustic emissions may be helpful in
evaluating the condition of the middle ear during the treatment.
Otoacoustic emissions are easy, practical tests for the
follow-up of effusional otitis media during the pre- and postoperative
period. Otoacoustic emissions may give valuable
information for applying ventilation tubes and help avoid
