A tumor can affect the al nerve and produce a neurofibromatosis. The symptom is usually a slow process, a terrible deafness of the sensory type that gradually worsens. Tinnitus accompanies it, and this gradually extends over 20-30 years. Dizziness in mild forms may occur, but this is seldom severe, the patient noticing clumsiness in walking. Vertigo may take place, and it may be confused with MeniCre’s disease. Later on there is involvement of other nerves, chiefly the facial nerve, that gives the telltale clue and makes a final diagnosis fairly certain.
However, in recent times, improved methods of diagnosis are bringing more to treatment at an earlier stage, Treatment is surgical, and current methods may produce relatively good results.
