Hipoacusia sensorioneural plana / Plane sensoneural hypoacusia

ABSTRACT

The authors intend to diagnose and make a prognosis in 97 patients surffering from sensoryneural hearing loss with a flat audiometric pattern. Combining this hearing loss with the hearing of the contralateral ear, seven different groups are abtained. The clinical records are searched for blood sedimentation rate, serologic tests for syphilis, eight nerve examination, ear X rays and when possible, fluctuations of hearing. When a vestibular lesion was found, this was mostly in the eat suffering from flat hearing loss. In most cases the hearing loss is either stable or gets worse. The most frequent diagnosis was endolinphatic hidrops
