Consideraciones anatómicas en la parotidectomía: Revisión de la literatura a propósito de un caso

Parotidectomy is a surgical procedure usually performed by Oral and Maxillofacial Surgeons and Head and Neck Surgeons, in which the parotid gland may be removed partially or totally. The most common indications for this procedure are the neoplasms of the gland. Approximately 80% of total salivary gland tumors occur in the parotid gland. Of these, 75-80% are benign. However, the parotidectomy is a highly complex procedure because of the regional anatomy and the close relationship of the parotid gland with the facial nerve. The most important aspect of this procedure is the functional preservation of the facial nerve and its branches. Therefore, the thorough knowledge of the anatomy of the parotid gland and related structures is necessary for surgical success. This review and case report will discuss the anatomical considerations that must be taken during parotidectomy to reduce the possibility of complications.
