Abstract:
Objective To observe the surgical results of milling technique in treating mandibular angle hypertrophy through an intraoral approach and the effect of three-dimensional computer tomography (3D-CT) reconstruction.Methods Milling-technique was used to treat mandibular angle hypertrophy of 43 patients through intraoral approach under local anaesthesia.3D-CT was applied preoperatively and postoperatively,the data of mandibular angle and masseter muscle thickness were compared preoperatively and postoperatively.The facial contour improvement was also observed.Results Of 43 cases,33 cases were followed-up for 4 to 24 months after operation.The majority of patients were satisfied with the aesthetic results,changes of anterior and lateral view of basifacial part were obvious,the curve of the mandibular angle was smooth and the shape was natural; no major complications such as facial nerve injury or malfracture were seen.Conclusions Milling-technique is a safe,effective and simple method for mandibular angle reduction,and 3D-CT reconstruction has a positive effect preoperatively and postoperatively.
