“… 1 , 2 Most of these schwannomas have vestibulocochlear origin 12 ; however, about 1%–12% occur in the oral cavity. 3 Detecting the nerve of origin in the oral cavity is often challenging. Sensory innervation of the posterior third and base of the tongue is performed by the glossopharyngeal and vagus nerves, and motor innervation of the tongue is performed by the hypoglossal and vagus nerves.…”

“… 1 It has been reported that about a quarter to a half of Schwannomas are found in the head and neck regions, 2 and about 1%–12 % of them are found in the oral cavity. 3 However, the tongue Schwannoma has a very low prevalence, and few cases have been reported. 4 , 5 , 6 Though the precise etiology of Schwannoma is unknown, some relevant risk factors like chronic irritation, external injury, stress oxidative, exposure to radiation, or genetic susceptibility have been reported in literatures.…”

“…Intracapsular excision with gentle dissection between the capsule of the tumor and normal fascicles reduces the chance of nerve damage. 46 The epineural layer covering the schwannoma capsule should be dissected in a pattern similar to peeling an onion to allow for safe removal of the tumor, which should be approached by its proximal and distal pole. The fascicles found in the tumor are often nonfunctional, so excision of these fascicles does not result in neurological problems.…”

Schwannomas are uncommon and benign neurogenic tumors that originate from the nerve sheath of the myelinated nerves. It can be found in any peripheral, cranial or autonomic nerves which contain Schwann cells. It is also called neuroma, nerve sheath tumor and neurilemmoma. Schwannomas in the head and neck region often present as painless swelling. The growth of schwannoma of the pinna causes an aesthetic alteration of the pinna. Schwannoma is a rare tumor of the pinna. The diagnosis of schwannoma is confirmed by histopathological study and immunohistochemistry. Histopathologically, it shows encapsulated, well-circumscribed lesions composed of different cellular patterns and arrangements. Histologically, the hallmark of schwannomas is the pattern of alternating Antoni A and Antoni B areas. The treatment of choice for schwannoma of the pinna is complete surgical excision. Recurrence following complete excision of the schwannoma is rare. Because of their rarity, these tumors are often not included in the differential diagnosis of the mass on the pinna. Preoperative suspicion and awareness are very important for schwannoma of the pinna to avoid delayed diagnosis and treatment. There is not much literature on the schwannoma of the pinna, indicating that this clinical entity is neglected. The objective of this article was to provide a comprehensive review of the schwannoma of the pinna including its epidemiology, etiopathology, clinical presentations, diagnosis and treatment.

“…26 The diagnosis of the ranula is done by fine need aspiration cytology (FNAC), ultrasound, magnetic resonance imaging (MRI), or computed tomography (CT) scan. 27 In FNAC, the aspirated liquid appears to be highly viscous in nature, with salivary content. 28 If the size of the ranula is greater than 2cm in diameter, or of plunging type, investigation such as CT, MRI or ultrasound is suggested.…”

A ranula is a pseudocystic lesion of the sublingual salivary gland, found in the floor of the mouth. Ranula is classified into types such as simple and plunging type. Plunging ranula arises when a simple ranula extends beyond the floor of the mouth into the neck. A simple ranula is seen above the level of the mylohyoid muscle and is often the result of sublingual gland duct obstruction. A plunging ranula refers to a pseudocyst that develops with salivary duct rupture and is seen below the level of the mylohyoid muscle. Diagnosis of the ranula is difficult even with modern imaging techniques as this mimic to other neck lesions. The correct diagnosis of the ranula is essential for the most effective treatment. The treatment modalities of the ranula currently include marsupialization, excision of the ranula with or without excision of the sublingual gland, cryosurgery, laser excision, sclerotherapy, fenestrations, and continuous pressure. The treatment of the ranula includes complete excision and marsupialization is not a sufficient treatment. Misdiagnosis of a plunging ranula leads to unnecessary and extensive surgery. This review article discussed the epidemiology, etiopathogenesis, clinical features, diagnosis, and current treatment of ranula.
