“…Facial nerve tumors contribute to approximately 5% of all facial nerve paralysis. Facial nerve schwannoma is the most common facial nerve tumor [ 3 ]. It may arise anywhere along the course of the facial nerve, from its origin in the cerebellopontine angle to its extracranial branches.…”

Facial nerve tumors constitute about 5% of all facial nerve paralysis. As it is relatively uncommon, it could be misdiagnosed. We encountered an 18-year-old girl who had right facial weakness since the age of four, referred to otorhinolaryngology clinic for further evaluation only when her hearing deteriorated and the facial weakness worsened. Further investigation revealed facial nerve schwannoma. Facial nerve paralysis in the pediatric age group is uncommon and should be examined in detail to rule out other possible etiologies besides Bell's palsy.

Schwannomas 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.

Introduction: Facial nerve schwannoma is a rare benign tumour involving any site of the facial nerve where schwann cells are present. Case report: A 29-year-old lady presented with right ear tinnitus for one year, associated with reduced hearing for the last six months. Otherwise no other cranial nerves were involved. Patient did not complaint of any facial twitching or vestibular symptom. Patient was then investigated using audiological assessment and imaging which concluded the diagnosis as facial nerve schwannoma. In view of normal facial never function, the patient received conservative management. Discussion: Symptoms may differ according to the location of the tumour and also compression on the adjacent structures, namely facial nerve palsy, hearing loss and tinnitus. Treatment option depends on the grade of facial nerve palsy and its prognosis post-surgery. Although the mainstay of treatment is surgical excision, every patient has to be individually assessed and treated accordingly. Conclusion: Facial nerve schwannoma commonly presents with facial nerve palsy, however, a normal facial nerve does not exclude a facial nerve schwannoma. Therefore, imaging such as HRCT of temporal bone and MRI of internal auditory meatus needs to be done to reach an early diagnosis thus preventing complications.
