OBJECTIVE To investigate the feas-ibility of preserving parotid duct in regional excision of pleomorphic adenoma. METHODS 32 patients with parotid pleomorphic adenoma were treated by regional excision with the preservation of the parotid duct. RESULTS No relapse occurred during 3-6-year follow-up period. Transient facial nerve palsy occurred in only 3.1%(1/32) of patients and the drainage of the parotid duct on the surgical side was preserved. CONCLUSION Remaining function of the parotid gland function was preserved and the facial nerve was well-protected in the regional excision of pleomorphic adenomas, especially for patients with small pleomorphic adenomas.
