Facial Nerve Schwannoma; 4 Case Reports.

AbstractSchwannomas are benign tumors arising from Schwann cells which are a protective casing of nerves, composing myelin sheath and can develop in any nerve where Schwann cells are present. Most common are vestibulocochlear nerve schwannomas. Facial nerve schwannomas (FNSs) are uncommon tumors involving seventh nerve of which geniculate ganglion involvement is most common. Clinical presentations and the imaging appearances of FNSs are influenced by the topographical anatomy of the facial nerve and vary according to the segments involved. We report a case of 73-year-old man presenting with right side facial weakness of lower motor neuron type involvement. Computed tomography and magnetic resonance imaging are clinching the diagnosis. An early diagnosis is important in containing the disease facilitating early surgical intervention.

Facial Nerve Schwannoma

Significance Statement Facial nerve schwannoma is extremely uncommon. Despite its rarity, it is considered the most common facial nerve tumor and potentially affects any segment of the nerve. Presenting symptoms vary depending on the location of the neoplasm. Tumors pertaining to the extratemporal course of the nerve mainly appear as an asymptomatic parotid mass. We present a rare case of schwannoma of the zygomatic branch of the right facial nerve that was surgically resected, without facial nerve injury.

Physical Findings

Facial paralysis in the presence of a parotid mass has been associated classically with a presumed diagnosis of malignancy. However, isolated case reports have documented the occurrence of paresis or paralysis secondary to pathologically benign, nonneurogenic parotid lesions. These previous cases have been reviewed and three additional cases are described. Comparisons are made on age, sex, symptoms, physical findings, pathologic findings, and prognosis. Involvement of the seventh nerve may be explained on the basis of compression, especially in association with local inflammation. Although facial paralysis still should be considered indicative of a malignancy, it also may be caused by benign masses, particularly those associated with rapid enlargement and/or infection.
