Comprehensive Review On Surgical Anatomy Of Parotid Duct

Background: Parotid duct also known as stenson's duct is known for its characteristic course and variability in number as well as branching pattern since its discovery with variation prevalence rate of 20-30%. It carries secretions of parotid gland into the oral cavity. Distinguishing patterns of the commencement, dimensions and branching of the duct are reported in the literature. The knowledge of the surgical anatomy of the duct is essential for parotid and maxillofacial surgery because of its close association with the facial nerve. Dimensions of the duct are clinically significant for all endoscopic interventions like transductal facial nerve stimulation, sialoscopy, lithotripsy and procedure for ductal stenosis. Present article is a comprehensive review of surgical anatomy of the parotid duct along with embryological basis of variations integrating with clinical relevance which makes its useful for diagnostic accuracy, interventional procedures and therapeutic outcomes.
