ABSTRACT:
Introduction: An accessory parotid gland is the salivary tissue present in close association to the Stenson’s duct lying on the masseter but away from the parotid gland. The most common location of accessory salivary gland tissue is an extra major salivary gland in front of the parotid gland. Accessory parotid tissue is found in 21-56% of adults. Any disease process which affects salivary glands may affect accessory parotid gland.
Objectives: present study was conducted to study the morphology of parotid gland, structural variation including accessory parotid glands in Indian population.
Materials and Methods: A total of 50 cadaveric dissections of parotid glands were studied. The Weight was measured in gms, cranio-caudal and ventro-dorsal dimension was measured in cms. Average and standard deviation was calculated. Accessory parotid gland was explored and examined.
Results: Out of 50 dissections overall incidence of accessory parotid gland was noted in 5 (10%) of cases. Bilateral accessory gland was noted in 2 (4%) of cases. Unilateral accessory parotid gland was noted in 3 (6%) of cases.
Conclusion: Accessory parotid gland is a prominent morphological variation in Indian population.
Key words: Morphological Variations, Structural Variation, Parotid Gland, Cadaveric Study, Ectopic Salivary Tissue.
