Studies on the Hearing and the Tubal Function in a Series of Children with Cleft Palates: (Preliminary report)

Abstract

The study involves hearing data obtained from pure tone air conduction threshold tests of 121 children with cleft palates. 60 children show hearing losses bigger than 20 db at two frequences. 71 subjects show abnormal tympanic membranes, the subject classification includes tubal function tests with employment of impedance measurements of the middle ear.
