Intraparotid Facial Nerve Schwannoma is an exceedingly rare tumor of head and neck region. It forms about 0.5% - 1.2% of all parotid tumors. It is neuroectodermal in origin. Facial nerve schwannomas are benign, encapsulated, slow growing tumours that arise from nerve sheath. Most common presenting complaint is unilateral facial swelling though facial paralysis is seen in few of the patients. Fine needle aspiration cytology (FNAC) and radiology play a key role in preoperative diagnosis. Treatment of choice for fa-cial nerve schwannomas is complete surgical excision. Here we are reporting 5 cases of facial nerve schwannomas which lies within the parotid gland region. All the patients presented with unilateral facial swelling from the year 2017 to 2020. Clinical features, diagnosis and management of these cases are discussed here. We recommend that before going for excision, patient should be made aware of the possible functional facial deficit and as per the patient’s priority, decision of excision should be made. After complete excision, recurrence rate was found to be extremely low. Usually, post-operative functional deficit recovers almost completely with physiotherapy.
