Function-preserving parotidectomy for benign tumors involving the deep parotid lobe / 实用口腔医学杂志

ABSTRACT

Objective:To evaluate the advantages of function-preserving parotidectomy for benign tumors involving deep parotid lobe. Methods:17 patients with benign tumor involving deep parotid lobe were treated by limited partial parotidectomy.All of the tumors were not more than 3 cm of diameter,12 of them were in the deep lobe and 5 involving both superficial and deep lobes.In the operation fascia glandular flap was made,the tumor with the surrounding gland tissue was thoroughly dissected and the glandular parenchyma was preserved.Results:All the operations were successful and the wounds healed well with symmetrical facial contours.No patient experi-enced salivary fistula.Temporary facial palsy was observed in 2 cases(11.76%).No tumor recurrence was observed.Facial nerve function of all patients completely recovered after a median follow-up of 11 months.Conclusion:Function-preserving parotidectomy for benign tumor involving the parotid deep lobe may improve functional outcomes without compromising local tumor control.
