<unk>  may be classified according to pathology into 4 subtypes: conventional<unk> , cellular<unk> , plexiform<unk> , and melanotic<unk> . Based on location it is classified into intracranial<unk> ,Acoustic neuroma (most common),trigeminal<unk> , facial nerve<unk> .<unk> s are composed of spindle cells which demonstrate two growth patterns Antoni type A and Antoni type B. Antoni type A patternin which elongated cells are densely packed and arranged in fascicles. Palisades are sometimes seen, when prominent these form verocay bodies. Antoni type B pattern cells are less compact and are prone to cystic degeneration.<unk>  variants include ancient<unk> , cellular<unk> , melanotic<unk> , plexiform<unk> . The incidence vestibular<unk>  is approximately 1 per 100,000 individuals. People of all age groups may develop vestibular<unk> . The incidence is more common between the 3rd and 5th decades of life. The median age at diagnosis is 5th decade.Symptoms of intracranial<unk>  include hearing loss, tinnitus, dysphagia, ataxia, Vertigo, Facial weakness, Dizziness, spinal<unk> s present with Back pain, Urinary incontinence, Urinary retention, Clumsiness, Weakness, Paresthesias. Surgery is the mainstay of treatment for<unk> . There are three main approaches like translybyrinthine, retrosigmoid, middle fossa. The common complications of surgery include vertigo, hearing loss is another important complication associated with the operation, post-operative headache, cerebrospinal fluid (CSF) leakage, facial paralysis
