ABSTRACT

Objective To explore the clinical effect of endoscopic-assisted intraoral reduction mandibuloplasty.Methods From January 2010 to December 2014,a total of 186 patients with prominent mandibular angles underwent one stage long-curved ostectomy combined with splitting corticectomy through an intraoral approach with endoscopic assistence according to preoperative design for reduction mandible three-dimensionally,and achieved reduced width of the lower face with smooth curve of mandibular edge.The distance between both gonions was measured and the complications recorded to evaluate the clinical effect of the surgery during follow-up.Results All the 186 patients had no complications of bleeding and infection.The mean distance between both gonions measurement was (117.3±2.5) mm before surgery and (102.6±2.3) mm after operation;it was reduced (14.1 ±2.4)mm.After 1 month to 2 years of follow up,the width of the lower face was reduced in the frontal view and the mandibular angle appeared natural and inconspicuous in the lateral view.The patients were satisfied with both their frontal and lateral appearances.Conclusions Intraoral approach mandibular ostectomy with endoscopic-assisted allows surgeons to perform accurate,safe and reproducible ostectomies and to recontour mandible symmetrically and reduce the complications.
