ABSTRACT

OBJECTIVE To discuss the surgical methods and their long term efficacy of management of the parotid tumor.METHODS The clinical data of 86 cases with parotid tumor underwent operation between 1997 and 2004 in our hospital were retrospectively analyzed.There were 53 male and 33 female with their age from 23 to 84 years(mean 57 years old). All the patients underwent superficial parotidectomy or extensive superficial parotidectomyenl or total parotidectomy.Selective or functional neck dissection was carried out in some cases.The function of facial nerve was evaluated after operation in all patients. Postoperative radiotherapy was performed in all malignant cases with a dose of 50 to 70 Gy.The patients were followed-up for 36 to 120 months.RESULTS There were 73 benign cases and 13 malignant cases. Five of 8 malignant tumors were found in deep lobe gland.Only one benign tumor locally recurred.The local- regional control rate of the benign tumor was 98.3%. The 3-year survival rate and local-regional control rate in malignant neoplasm were 69.2 % and 84.6 % respectively.The cervical lymph nodes metastasis rate was 23.1% in postoperative pathologic study.The facial nerve preservation rates were 97.3 % and 69.2 % in benign and malignant cases respectively.CONCLUSION The superficial parotidectomy is the basic surgical method.Extensive superficial parotidectomy or total parotidectomy can be used if necessary.The facial nerve and its branches should be preserved during operation. The malignant tumor is more frequently found in deep lobe of the parotid gland.
