Abstract
Introduction: A hearing– impaired patient is defined as one with abnormal or reduced function in hearing resulting from an auditory disorder. The goal of any preschool and schools screening program should be to accurately indentify those children whose hearing has been impaired due to conductive and / or sensory– neural pathology.
Methods: This cross– sectional descriptive study was done on 577 children (299 girls and 278 boys) aged between 3–6 years at kindergartens of Yazd city from September 2005 to January 2006. The otoscopy examination, pure-tone screening and impedance study was conducted after completion of awareness form of the hearing loss existence by the parents.
Results: In this study, there were 12.6% abnormal conditions of external ear canal, 34.2% abnormal tympanic membrane, 35.9% abnormal tympanograms and 13.4% hearing loss including 11.5% conductive hearing loss, 1.5% sensory-neural hearing loss and 0.5% mixed hearing loss.
Conclusion: With respect to the high prevalence and negative effects of middle ear disorders in learning of preschool children, and also due to the importance of early identification and intervention of hearing loss in aural rehabilitation programs, increasing the awareness and education of people, especially parents about the effects of hearing disorders and its prevention and identification is very important

Abstract
Introduction: Otoacoustic emissions are low density sounds produced from intact cochlea measureable in the presence of an intact conduction structure. The goal of this study was to assess the surgical success rate after tympanostomy tube insertion by Distortion Product Otoacoustic Emission (DPOAE) and Transient Evoked Otoacoustic Emission (TEOAE) as methods of evaluation of postoperative hearing.
Methods: A descriptive-analytic study was conducted on 130 patients with OME. Audiometrical tests included TEOAE, DPOAE that were performed before, one month and three months after surgery on patients and results were compared.
Results: Prior to surgery, TEOAE and DPOAE responses were not recordable in any of the patients, whereas after surgery, the responses were significant.
Conclusion: OAE tests can be used as objective, simple tests in children, especially in toddlers who are not able to cooperate in performing PTA before surgery. These tests can be also be used for follow up of patients for hearing loss improvement and resolvement of middle ear effusion.
