[High frequency audiometry].
The authors have performed a series of high frequency audiograms in order to assess its value in routine otological practice. Initially, they conducted a statistical study on subjects with so-called normal hearing in order to establish standardised normal values. As in the earlier studies, a physiological alteration was observed in the high frequencies which was progressively accentuated with age. Audiometric results should therefore always be considered in relation to the patient's age. A standard graph is proposed for the presentation of the results. The authors subsequently performed high frequency audiometry in patients with internal ear disorders. High frequency audiometry allowed early detection of an alteration in the internal ear, when conventional audiometry was normal. The authors believe that high frequency audiometry should be part of the otological assessment as its allows early detection of internal ear disease.
