Clinicopathological evaluation of parotid gland tumors: a retrospective study.
Two hundred and thirty sequential parotid tumors seen from March 1985 to 1995 were reviewed for their clinical presentation, diagnostic evaluation, pathological diagnosis, treatment modalities, and age and sex distribution. An asymptomatic mass was the most common clinical presentation. All of the operations were performed by the same surgical team. Total and superficial parotidectomy was used for the treatment of the lesions and none of the patients underwent limited excision. Retrograde approach in 79 (34.4%) patients and anterograde approach in 151 (65.6%) was used. Eighteen patients with malignant tumors were followed up in cooperation with the radiation oncology clinic. Tumors were classified according to their histopathologic diagnosis. Among 192 (83%) benign and 38 (17%) malignant tumors, the most common benign tumor of parotid gland was pleomorphic adenoma (79.1%) while the most common malignant lesion was adenocystic carcinoma (44.7%). Incidences of pleomorphic adenoma, adenocystic and epidermoid carcinoma were greater in male patients. Complication rates in benign and malignant tumors were presented and statistically significant difference could not be found between anterograde and retrograde approach in terms of facial nerve injury (P > 0.05).
