The prognosis of the facial dysfunction was favourable in the majority of cases, and, in fact, there were only five grade III to IV cases 1 year later. Facial dysfunction was over grade III in the majority of the latter five cases, and the period of recovery was long.

Vestibular schwannomas are found in about 1 in every 100,000 people in the United States each year. Also known as “acoustic neuromas,” these tumors are usually diagnosed in adults in one ear and are not hereditary. Unilateral sensorineural hearing loss is the most common symptom, followed by intermittent dizziness and facial numbness. Larger tumours may cause headaches, coordination difficulties, and obstructive hydrocephalus, and, as a result, may be life threatening. Diagnosis is confirmed by gadolinium-enhanced magnetic resonance imaging scan. Schwannoma is a benign, slow-growing tumor that does not spread to other parts of the body.

As the vestibular schwannoma grows, it affects the hearing and balance nerves, usually causing unilateral (one-sided) or asymmetric hearing loss, tinnitus (ringing in the ear), and dizziness/loss of balance.

Vestibular schwannomas expand slowly in the internal auditory canal, in the cerebellopontine angle, inside the cochlear and the labyrinth. Larger tumors can displace and compress the brainstem. With an annual incidence of 1:100 000 vestibular schwannoma represent 6-7% of all intracranial tumors. In the cerebellopontine angle they are by far the

A first degree Vestibular schwannomas or acoustic neuromas are the most common and typically cause hearing loss and ringing in the ears (tinnitus); as they enlarge they may also cause imbalance and incoordination as well as facial weakness. Trigeminal schwannomas are less common and typically case facial numbness, tingling or facial pain.

Background In patients with a vestibular schwannoma, some studies have reported that useful hearing preserved initially after surgery deteriorates gradually in the long term. Studies with more patients are needed to clarify the maintenance rate of postoperative hearing function and to identify prognostic of hearing function.

Usually, vestibular schwannomas start in the Schwann cells on the outside of the vestibulocochlear nerve. The vestibulocochlear nerve connects the brain to the ear. It controls hearing and balance. Vestibular schwannomas do not spread to other parts of the body.

If muscle weakness occurs in an area affected by a schwannoma, the affected muscle might not regain full strength after the tumor is removed. Hearing loss due to a vestibular schwannoma or its treatment is usually permanent. Large schwannomas have a low recurrence rate. Long-term monitoring and follow-up care may be required.
