10 Symptoms of a Acoustic Neuroma
Symptom #6: Facial Numbness
In acoustic neuroma, involvement of the trigeminal nerve can lead to intermittent or constant facial numbness or tingling. The trigeminal nerve can be divided into three branches on each side of the face: the ophthalmic, maxillary, and mandibular nerves.
While the first two are purely sensory, the mandibular nerve supplies both motor and sensory functions. Facial numbness or tingling is usually felt on the side of the face affected by the acoustic neuroma.
