Several symptoms such as Hearing loss, head ache, tinnitus etc was associated with patients with acoustic schwannoma. A high-frequency sensory-neural hearing loss is the most common type, occurring in approximately two-thirds of patients. However in Indian population the presentation of symptoms, the order of symptoms is not known. The present retrospective study was attempted to account for the frequency of symptoms onset, degree of hearing impairment as well as the measures of distortion product otoacoustic emissions, auditory brainstem responses and acoustic stapedius reflex. The analysis was done on 100 confirmed patients (44 females and 56 Males) of acoustic schwannoma. The patients were in the range of 45-60 years with a mean age of 52 years (SD = 2.5). The present study has revealed hearing loss as the most common symptom in 90% of the patients which is in agreement with other studies. The cochlear pattern was observed in 63.4% of patients while 36.6% was non-cochlear type.
