“…They include deafness, ageusia, reduced lacrimation and signs of intra-cranial space occupation. The most common presenting feature is facial weakness or paralysis, occurring with a frequency of 100 per cent (Curtin and Lanigan, 1964;Isamat et al, 1975;Anand et al, 1977;Liliequist, 1978;Baur and Greisen, 1984;Jung et al, 1986) in most reported series. Murata et al, (1985) quote a frequency of facial paresis of just over 90 per cent.…”

“…Facial nerve schwannomas are relatively rare tumours with 183 cases having been reported (Curtin and Lanigan, 1964;Stewart, 1966;Hoshino and Paparella, 1970;Isamat et al, 1975;Anandera/., 1977;Liliequist, 1978;Murataef a/., 1985;Jung et al, 1986). A slowly progressive facial palsy is the predominant feature in such cases and the role of surgical exploration of the nerve, for diagnostic purposes and removal of the tumour, has been stressed (Stewart, 1966;Isamat et al, 1975;Anand et al, 1977;Murata etal., 1985).…”

A 64-year-old man with right aural discharge presented complaining of progressive deafness. Other otological symptoms were absent and specifically there was no seventh nerve paresis. A right aural polyp was identified and biopsied. Histology showed the polyp to be a schwannoma. Subsequent temporal bone computed tomography showed expansion of the distal facial canal. At operation, the schwannoma filled the middle ear cleft and extended from the genu to the region of the stylomastoid foramen. The floor of the middle ear had been eroded, exposing the jugular bulb. Facial paresis is the usual presenting feature of a facial schwannoma, while deafness, ageusia and reduced lacrimation are variable, dependent upon the site of the lesion. The absence of facial palsy as a presenting feature is very rare and this case illustrates the need for histological examination of all abnormal aural material.

“…Repeated fine-needle aspiration biopsy may not always contribute to a correct preoperative diagnosis, and the tumor is sometimes identified only intraoperatively. 6 Facial schwannomas located in the labyrinthine portion of the facial nerve or at the geniculate ganglion show specific clinical and radiologic manifestations that can be distinguished from tumors of other portions of the nerve, petrous bone area, or the cerebellopontine angle. 7 However, a facial nerve schwannoma of unusual size in the temporal bone is one of the rare manifestations.…”

Conservative treatment with sparing of the nerve is considered in patients with small tumors. Excision of a large facial schwannoma with immediate hypoglossal nerve grafting as a primary procedure can provide satisfactory facial nerve function. One of the disadvantages of performing anastomosis is that there is not enough neural tissue just before the bifurcation of the main stump to provide neural suturing without tension because middle fossa extension of the facial schwannoma frequently involves the main facial nerve at the stylomastoid foramen. Reanimation should be processed with extensive backward mobilization of the hypoglossal nerve.

“…In two large series of brain tumors in children, there were no cases of schwannomas reported [2,4], Facial nerve schwannomas are even a more unusual occur rence; since the first reported case in 1930 in a 16-year-old girl, 103 cases had been reported for all ages in the world literature [1,3,5,7,8]. The age occurrence was reviewed in 38 cases in which information of the first symp toms was known and only in 12 cases were reported under the age of 20.…”
