title: Vestibular schwannomas: clinical presentation, management and outcome.
abstract: OBJECTIVE
  To review the demographic trends clinical spectrum, diagnosis, management and out come of patients with vestibular Schwannoma and to identify areas where improvements are needed.
  
  
  METHODS
  All patients with vestibular schwannoma admitted to the Aga Khan University Hospital over the past 11 years were reviewed retrospectively.
  
  
  RESULTS
  The age range of majority of 22 patients analyzed, was 41-50 years (23%). Hearing loss was the most common presenting symptom (96%). Other clinical features included cranial nerve palsies (59%) and headache (55%). Fifty percent had signs of raised intracranial pressure. Neuroimaging revealed "Stage IV b" (tumor distorting the brainstem and compressing the 4th ventricle) in 50% cases. Neurosurgical intervention was carried out in 86%; mainly using the retrosigmoid approach. Postoperative complications included facial nerve palsy in 13 (65%) and hydrocephalus in 5 (25%) patients. Hearing determined clinically was preserved in three patients (14%). One patient died during the inpatient stay.
  
  
  CONCLUSIONS
  Presentation of these patients is late and the outcome is poor.
