Acoustic impedance measurements and their importance in cleft palate patients.
There is a high incidence of middle ear pathology in cleft palate patients, secretory otitis media being the most common lesion. Impedence audiometry gives more valid information about conditions in the middle ear, as confirmed by exploratory paracenteses. Impedance audiometry, therefore, should be done as a routine, wherever facilities exist, in conjunction with the clinical examination.
