ABSTRACT

Background: Salivary gland lesions have been extensively studied for the purpose of accurate diagnosis, classification, and treatment. The incidence rates of salivary gland lesions in different geographical areas and study population are yet not published extensively. Objective: To calculate the incidence rates of salivary gland lesions and correlate them with the demographical and clinical data. Study design and Setting: Retrospective study design. Materials and Methods: Data of 117 salivary gland lesions were retrieved from the archives of the department from the year 2011–2020 and the lesions were categorized into cystic, neoplastic, and tumor-like lesions. The incidence rate of each of the lesions was calculated and correlated with the demographic and clinical data of the patients. Results: Most of the lesions were categorized as mucous extravasation phenomenon (76.69%), followed by mucous retention cyst (16.5%), basal cell adenoma (2.91%), pleomorphic adenoma (1.94%), and the least occurrence was seen for necrotizing granulomatous sialadenitis and sialoliths (0.97%). The age range of the patients with mucous extravasation phenomenon was 17–30 years, while of those with mucous retention cysts was 14–33 years; for basal cell adenoma was 45–50 years, while for pleomorphic adenoma was 30–35 years, and for necrotizing granulomatous sialadenitis and sialolith were 36 years and 45 years, respectively. Except for pleomorphic adenoma, all other salivary gland lesions were predominant in males. The cystic lesions had a predilection for lower lip, benign lesions for the parotid gland, and tumor-like lesions for the submandibular salivary gland. Conclusion: Over the study duration, 3.76% of the biopsies from the head and neck lesions were diagnosed as salivary gland lesions. The commonest salivary gland lesion was mucous extravasation phenomenon and all the lesions except the pleomorphic adenoma had a male predilection.
