Function-Preserving Surgery for Parotid Tumors: Intracapsular Versus Superficial Parotidectomy; A Randomized Clinical Trial.

Benign parotid gland tumors, such as pleomorphic adenoma and Warthin tumors, constitute the majority of salivary gland neoplasms. Surgical excision remains the primary treatment, traditionally achieved through superficial parotidectomy (SP). However, SP may lead to complications such as facial nerve dysfunction, Frey's syndrome, and aesthetic concerns. Intracapsular parotidectomy (ICP), a minimally invasive alternative, aims to minimize surgical morbidity while preserving oncologic safety. This study aimes to compare intracapsular parotidectomy and superficial parotidectomy in terms of operative efficiency, complications, facial nerve preservation, and tumor recurrence for benign parotid tumors.
