Facial nerve schwannomas (FNS) are encapsulated benign tumors arising from Schwann cells of seventh cranial nerve. Most of the facial nerve schwannomas are localized in intratemporal region; only 9% of cases involve a portion of the extratemporal segment. Preoperative diagnosis is often unclear; diagnosis is often made intraoperatively. Management of intraparotid FNS is troublesome because of the facial nerve paralysis. In this report we presented a case of intraparotid schwannoma in a 55-year-old male patient complaining of a painless mass without peripheral facial nerve palsy in left parotid gland. Clinical features, preoperative and intraoperative diagnosis, and difficulties during management are discussed with the review of the literature.

Nerve Of Origin

Extracranial schwannomas in the head and neck region are relatively rare neoplasms. The tumours are slow growing and often unnoticeable. The nerve of origin is unable to be determined until the time of surgery. Proper preoperative assessment of the disease can be done by imaging studies such as magnetic resonance imaging. The treatment for these tumours is surgical resection with preservation of the neural pathway. We report a case of left intraparotid facial nerve schwannoma in a middle-aged lady causing complete facial nerve paralysis. The clinical features, diagnostic possibilities and management are discussedBangladesh Journal of Medical Science Vol.17(4) 2018 p.680-682

Facial Nerve Schwannoma

<p class="abstract"><span lang="EN-IN">Schwannoma is a benign tumor arising from Schwann cells which is protective covering of nerves, called myelin sheath and can develop anywhere, where Schwann cells are present. Most common schwannomas are found with vestibulocochlear nerve. Facial nerve schwannoma are uncommon tumour involving 7th nerve out of which also most common site of involvement is geniculate ganglion. Facial nerve schwannoma is uncommon benign tumor. There are no typical patterns of presentation and can easily go untreated or misdiagnosed. Facial nerve palsy is most common mode of presentation. Here we present a case of 35 years male who presented with complaint of facial nerve paralysis. High degree of clinical suspicion and early imaging can lead to diagnosis. An early diagnosis is important as morbidity associated with this disease and as well as surgery leads to delay in diagnosis.</span></p>

Facial Nerve Schwannoma

Objective: To present a rare case of facial schwannoma manifesting as a parotid mass and discuss its diagnosis and treatment.Methods:     Design: Case Report     Setting: Tertiary Government Hospital     Patient: OneResults: A 48-year-old female was seen for a 2-year progressive left hemifacial paralysis and a 5-month gradually enlarging left infraauricular mass with episodes of tinnitus but intact hearing and balance. Physical examination showed a left-sided House Brackmann grade VI facial paralysis and a 5 x 4 x 3 cm soft, ill-defined, slightly movable, nontender, left infraauricular mass. Gadolinium-enhanced magnetic resonance imaging revealed a 5 cm heterogeneouslyenhancing lobulated mass centered within the deep lobe of the left parotid gland extending to the left mastoid, with facial nerve involvement. A diagnosis of a facial nerve tumor, probably a schwannoma, was entertained. Pure tone audiometry revealed normal hearing thresholds for both ears with dips at 6-8 KHz on the left. The patient underwent total parotidectomy withfacial nerve tumor resection via transmastoid approach, with simultaneous facial – hypoglossal nerve anastomosis reconstruction. Histopathologic findings confirmed the diagnosis of a schwannoma. Postoperative facial function was Grade VI. Hearing and hypoglossal nerve function were preserved.Conclusion: A progressive hemifacial paralysis of chronic duration with or without the presence of an infra-auricular mass should raise the suspicion of a facial nerve tumor. Gadolinium-enhanced magnetic resonance imaging is valuable since intraparotid facial nerve schwannomas are mostly diagnosed intraoperatively when the neoplasm and the nerve are exposed and determined to be contiguous. The clinician should be aware that not all parotid masses are salivary gland in origin.Keywords: intraparotid facial nerve schwannoma, facial nerve paralysis, parotid mass

Background: Chronic osteomyelitis mandibula is one of the complications from dental extraction. Inadequate wound handling can have an impact on the spread of infection in the surrounding tissue like nerve which results in facial nerve paralysis. The purpose is to present a rare case that facilitative nerve paralysis as a result of the spread of osteomyelitis infectionCase Management: A 69 years old woman with chief complains numbness onher lips accompanied by pus out beside the lower teeth. No sistemic disease. Panoramic radiograph showed abnormal bone-like sequester. Extraoral examination appeared the bluish color on the right cheek and there was right facial muscle paralysis. Debridement, sequesterectomy by general anesthesia and medication using ceftriaxone intravenous, ketorolac injection, multivitamin, and corticosteroid, physiotherapy for facial nerve paralyze, also.Discussion: Pathogenesis mandibular osteomyelitis involves contiguous spreadfrom an odontogenic focus infection. The bacteria produce an exotoxin, which, while unable to cross the blood-brain barrier, can have deleterious effects on thePeripheral Nerve System (Fasialis Nerve) in up to 75% of cases, with the severity of presentation correlating with the severity of the infection.Conclusion: Chronic mandibular osteomyelitis can spread the infection to around another anatomy oral cavity like facials nerves.
