Vestibular Schwannoma

A Vestibular schwannoma is the most common type of benign tumor originating from the nerve sheath (shwanN cells).  It most commonly presents with auditory symptoms (tinnitus and hearing loss), or vestibular (transient vertigo and balance difficulties).

The tumor growth of a vestibular schwannoma is unpredictable. It is known that 20% of them may not grow at all over time, 40% will grow slowly, and 40% will grow fast (doubling in size in less than two years). It is best practice to determine the pattern of growth of a vestibular shwannoma before deciding on what to do. While intervention (surgical or radio-surgical) makes sense when the tumor is rapidly growing, observation alone is the correct choice when dealing with a tumor that is not growing.  We believe that experience and solid data should guide the management of these tumors.
