Introduction[edit | edit source]
Facial Schwannoma is a very rare tumour which grows on the 7th Cranial Nerve, the Facial Nerve.
It is also known as a Facial Neuroma.
Clinically Relevant Anatomy[edit | edit source]
For details of the path of the Cranial Nerve 7, please see the Facial Nerve page.
Location of Tumour[edit | edit source]
The majority of tumours are found on the segment of the nerve within the internal auditory canal, with one UK study[1] of a cohort of 28 Facial Schwannoma patients reporting 68% incidence in this section of the nerve.
The same study also found multi-segmental lesions in 46% of the patients.
Facial weakness was most commonly associated with involvement of the labyrinthine segment (89%).
Mechanism of Injury / Pathological Process[edit | edit source]
Schwannomas are extremely slow growing tumours, the majority of which are benign[2].
They originate from the Schwann cell sheath of the facial nerve.
Clinical Presentation[edit | edit source]
The presentation frequently comprises hearing loss and facial weakness or paralysis.
