Parotid duct blockage is a complex condition that requires prompt diagnosis and treatment to prevent complications. A thorough understanding of the causes, symptoms, diagnosis, and treatment options is essential for healthcare professionals to manage this condition effectively. By providing a comprehensive overview of parotid duct blockage, this report aims to enhance the knowledge and awareness of this condition, ultimately leading to improved patient outcomes.

The parotid duct is a narrow, muscular tube that originates from the anterior border of the parotid gland and traverses the masseter muscle, buccinator muscle, and buccal fat pad before emptying into the oral cavity. The duct is approximately 5-7 cm long and 2-3 mm in diameter. It runs anteriorly across the masseter muscle, then turns medially to pierce the buccinator muscle and opens into the oral cavity at the level of the second upper molar.
