“…Depending on the size and location of the tumour, there may exist hearing loss, as reported in 10 previous cases [2][3][4][5][6][7][8][9][10][11] and in our patient (Table 1). Interestingly, seven patients showed a mass in the external ear canal [3][4][5][6][7][8]10] . Only two cases were associated with neurofibromatosis [2,14] .…”

Tumors of the chorda tympani are extremely rare. To date only 15 cases have been reported in the literature. Slow growing rate and nonspecific clinical features allow these lesions to reach a large size and resemble more common otological entities such as cholesteatoma. Diagnosis is usually established after surgical resection. However, lack of specifity of conventional pathological studies emphasizes the importance of immunohistochemical studies for final diagnosis. It is advisable to use the correct terms when reporting the histology of chorda tympani tumors in literature.

“…Thus, preoperative fine-needle aspiration cytology can be extremely useful. 10 Alternatively, as in our Case 2, a micro-otoscopic transcanal incisional biopsy can provide histopathological data. CT and MRI are required to plan surgery.…”

“…This finding is associated with a rare entity, a chorda tympani neuroma. 10 The chorda tympani alone was involved in nine reported cases. [10][11][12][13][14][15][16][17][18] Our Case 2 adds the tenth such case to the English literature.…”

Facial Nerve Neuroma: Clinical, Diagnostic, and Surgical Features

Facial nerve neuromas are uncommon benign tumors. The diversity of tumor locations and their proximity to vital neurovascular structures create a variety of clinical situations, and the management strategy for each case differs. Two cases with tumors located at different sites and associated with different clinical presentations are discussed in terms of diagnosis and management.KEYWORDS: Neuroma, facial nerve, chorda tympani, paralysis Facial nerve neuromas are uncommon benign neoplasms of Schwann cells. They compose only 0.8% of all intrapetrous mass lesions. 1 More than 300 cases have been reported since they were described by Schmidt in 1930. 2 These tumors can arise from any segment of the nerve from the cerebellopontine angle to the extratemporal peripheral portion. 3,4 The diversity of locations involved with the tumor and their proximity to the auditory apparatus can create a variety of clinical situations. 4 Thus, the site of the tumor, its extension, and the way it involves the surrounding structures determine the surgical approach.This article presents two cases of facial nerve neuroma involving different locations and clinical manifestations, focusing on the diagnostic and therapeutic problems encountered. CASE REPORTS Case 1A 38-year-old woman sought treatment for left facial paralysis, dizziness, and hearing loss and tinnitus in her left ear that had been present for about 1 year. Otoscopy revealed an intact tympanic membrane. A reddish mass was seen behind the tympanic mass. Neurological examination revealed total facial paralysis (i.e., House-Brackmann grade VI). Pure-tone audiometry indicated unilateral sensorineural hearing loss in the left ear with airand bone-conduction thresholds elevated to 60 dB hearing loss. The tympanogram was type-B on the left side. The acoustic reflex was absent to acoustic stimuli on the left side. Computerized tomography

“…Patients present with slowly worsening conductive type hearing loss, tinnitus, and rarely facial weakness, or paralysis. Since facial paralysis is rarely appreciated in initial presentation and is mainly seen due to the mass pressure effect on the facial nerve itself; some authors advocate CTS as a distinct subgroup of facial nerve schwannomas ( 6 , 7 ). Accordingly, asymptomatic CTS cases have been reported in the literature ( 2 ).…”

Chorda tympani schwannomas are rare benign tumors of the middle ear cleft. This is a case of incidental chorda tympani schwannoma identified intraoperatively. The patient was a 50-year-old male with chronic active otitis media complicated by left-sided facial paralysis. During closed mastoidectomy and tympanoplasty approach, a well-demarcated swelling on the left chorda tympani nerve was identified and sectioned for pathologic evaluation. The histopathologic evaluation established the diagnosis of schwannoma. Although the tumor was unlikely the cause of the disease process in this patient, his facial paralysis and middle ear disease were resolved after surgery.
