Introduction: Salivary gland neoplasm represents the most complex and diverse group of neoplasm of the head and neck. Their diagnosis and management are complicated by relatively infrequency. The parotid gland shows 64- 80%, the submandibular glands showed 7-11% and the remainder being distributed between the sublingual (1%) and the minor salivary glands (9-23%) throughout the oral cavity.
Aim: 1) To assess the frequency of salivary gland tumor based on tumour type and anatomic location. 2) To correlate gender and age in different tumour type. 3) To correlate the location of benign and malignant tumours.
Materials and methods: A retrospective study was done in the Department of Oral Medicine and Radiology from the period of January 2006 to December 2017, data was collected from the archives maintained in the department of Oral Medicine. Details of the patient include age, sex and site of the tumour were obtained and confirmed with histopathological study.
Results and Discussion: Chi square test was applied to find out the distribution of malignant and benign tumours. The prevalence of salivary gland tumors in our study was 0.3%, and the benign: malignant ratio was 1:2.2, with mean age of occurrence
Conclusion: This study was a single institutional experience where analysis of 32 SGTs was carried out. Malignant tumours were more compared to benign. Among benign tumours pleomorphic adenoma was the most common type. Among the malignant salivary gland tumors mucoepidermoid carcinoma was the most common followed by adenoid cystic carcinoma then ex pleomorphic adeno carcinoma followed by low grade polymorphous adeno carcinoma.
