INTRODUCTION: The study of tumours of parotid gland is a fascinating and a novel one but sometimes this seemingly familiar disease remains a trouble to both the patient and the surgeon. There is a real threat of injuring the facial nerve, but with a striking change in the attitude of medical profession towards proper understanding of anatomy of parotid, especially of facial nerve and its intricate relationship to the gland, the danger is becoming less nowadays. Similarly thorough knowledge about various characteristics of each type of tumour arising from parotid and their response to various modalities of treatment is necessary for adequate management of these neoplasms. AIM OF THE STUDY: The following are aims of our study: 1. To analyze the incidence of different tumours occurring in parotid gland. 2. To study the mode of presentation of benign and malignant neoplasms. 3. To study the accuracy of FNAC in diagnosing the tumours preoperatively. 4. To identify any common predisposing factors. 5. To monitor the post operative facial nerve weakness. MATERIALS AND METHODS: Our study conducted at Kilpauk Medical College and Hospital (KMCH) during the period from September 2004 to September 2006, included those patients who attended the General Surgical clinics for the first time with complaints of parotid swelling. The selection of the patients has been done at random included both the sexes and all age groups. These patients were subjected to thorough clinical examination. All the basic investigations necessary for anaesthetic assessment and specific investigation for confirming the diagnosis namely FNAC were done. CT scan was also done for appropriate patients. A review of 36 patients was done. Out of 36 patients 19 were male and 17 were female. A thorough analysis of the incidence rates, (according to age & sex), the symptomatology, pathology, and treatment adopted was done. CONCLUSION: 1. Parotid tumors are not an uncommon entity. 2. The most common presentation of parotid tumors is painless swelling. Hence any solitary swelling in the parotid gland must be considered as tumor until proved otherwise. 3. The most common age group to be involved is between 40 - 50 years. 4. There is no sex or side predilection. 5. There are no definite predisposing factors for parotid tumors. 6. The most common tumor occurring in parotid gland is pleomorphic adenoma. The most common malignant parotid tumors are mucoepidermoid carcinoma and adenocarcinoma. The benign parotid tumor, pleomorphic adenoma present as painless swelling with no evidence of facial nerve weakness and the duration of symptoms is usually more than one year. 7. Clinical signs such as hard consistency, fixity, facial nerve palsy are seen most commonly in parotid tumors and hence these features can be used as diagnostic criteria preoperatively. 8. FNAC is very effective in the pre operative diagnosis of parotid tumors and it has no complications. 9. Post operative facial nerve weakness occurred in 16% with in 25% cases in our study.
