Clinical reaserch on 57 parotidectomy surgery patients with reverse separate facial nerve along marginal mandibular branch

Objective: To study the effect of resection of parotid tumors by retrograded and anatomized on marginal mandibular branch to separate facial nerve. Methods: 57 patients for resection of parotid tumors from January 2003 to January 2008 were analyzed.The way separating facial nerve by retrograded and anatomized on marginal mandibular branch to separate facial nerve was adopted for all patients. Results: All operations were successful. Parotid fistula appeared in 2 patients,facial nerve injury appeared in 3 cases. Conclusion: The way of reversing separate facial nerve along marginal mandibular branch was from shallow soft tissue to deep. It is an effective surgery way for convenient manipulation,clear field of operation, minimal trauma,less bleeding.
