SALIVARY GLAND TUMOURS;
FREQUENCY OF SALIVARY GLAND TUMOURS
Keywords:Salivary gland tumours,, Pleomorphic adenoma.
Objectives: The objective of the study was to find the frequency of salivary
gland tumours. Study Design: A descriptive study. Period: 1st Jan 2008 to 31st Dec 2010 (of 3
years duration). Setting: ENT department Khyber Teaching Hospital and Surgical department
Hayatabad Medical Complex, Peshawar. Material and methods: Total number of 108 patients
having salivary gland tumours enrolled from admitted patients in ENT department Khyber
Teaching Hospital and Surgical department Hayatabad Medical Complex Peshawar. The
study was designed to find the frequency of salivary gland tumours. Results: In our study
most of the patients were having benign tumours (80.6%) with malignant counterpart in about
19.4%. Overall the most common tumour was pleomorphic adenoma about 71.3% followed by
Mucoepidermoid 6.5%, adenoid cystic carcinoma 4.6% and Warthin’s tumour 4.6%. The most
commonly involved salivary gland is parotid gland about 78.7% (85/108) with pleomorphic
adenoma being the most common benign tumour and Mucoepidermoid the malignant variety.
In submandibular gland/ sublingual glands the most common was pleomorphic adenoma
and in minor salivary gland majority were malignant. Conclusion: Most of the salivary gland
tumours are benign with majority of them are pleomorphic adenomas and parotid gland is the
most common involved salivary gland.
