Abnormal conditions of external ear canal was statistically unmeaningful. (P V=0 .8) 2- Impedance Audiometiy: 5. 75% Abnormal tympanograms were observed, mostly type C (3.15%) 3- Pure Tone Audiometry: An overall 5.5% hearing loss was found in this population including 3% bilateral and 1.25% unilateral hearing loss.
