Lower cranial nerve (LCN) schwannomas are rare, benignperipheral nerve sheath tumours arising from cranialnerves IX–XII. Though uncommon, they pose significantclinical challenges due to their complex anatomicallocation and potential for neurological deficits. Jugularforamen schwannomas (JFS) and hypoglossalschwannomas (HS) are the most prevalent subtypes.Clinical presentation varies by nerve involvement, rangingfrom hoarseness and dysphagia to tongue atrophy andparoxysmal cough. Diagnosis relies heavily on MRI and CTimaging, with differentiation from paragangliomas beingcritical. Classification systems guide surgical planning, withgross total resection (GTR) being the goal, though subtotalresection (STR) is preferred in cases with dense neuraladherence to preserve function. Gamma knife radiosurgery(GKRS) offers an effective alternative for small or residuallesions. Treatment must balance tumor control withpreservation of neurological function, requiring amultidisciplinary and individualized approach.Keywords: Schwannoma, Benign Neoplasms, Cranial nerveneoplasms
