Traumatic facial nerve neuroma following mastoid surgery: a case report and literature review

Traumatic facial nerve neuroma is rare. There are only 10 reported cases in the literature, caused either by physical trauma or chronic inflammation. Traumatic facial neuromata differ from true facial nerve neoplasms in radiological, macroscopic and microscopic appearance, but clinical presentation is less reliable in differentiating the two. Management depends on the pre-operative grade of facial palsy, as this is a benign condition and surgical management carries a risk of further affecting facial nerve function. We present a further case of traumatic facial nerve neuroma following surgery for cholesteatoma. We also review the literature and discuss the management of this condition.
