Combined mandibular angle resection with lateral cortex splitting ostectomy around mandibular angle by intraoral approach for correction of square face / 中华医学美学美容杂志

Objective To search for a procedure for correction of square face. Methods 68 patients with square face (aged from 21～40 years, with 65 females and 3 males) underwent osteetomy combined mandibular angle triangle resection with lateral cortex around the mandibular angle-splitting by intraoral approach. The mandible outer cortex was splited with bone chisel and mandible angle was resected by the high-speed pneumatic drill. The bulky masseter muscle and the enbonpoint buecal fat-pad were scissored. Results The application of high-speed pneumatic drill and bone chisel facilitated resection of the mandibular angle with lateral cortex splitting osteetomy. The operative effects were satisfactory in 56 patients during 3-24 months of follow-up. The bigonial distance was effectively re-duced, and facial shape became ellipse. The gross asymmetry and mandibular fracture were not conse-quences. The lateral contour of the mandibular angle was natural. Conclusion Ostectomy of mandible angle and lateral cortex of the mandible allows the reduction of the mandibular contour of the frontal view and the lateral contour of mandibular angle becomes soft, giving a more natural appearance. This new method is worthy to be applied widely because of the good result with effective reduction of the mandibular width.

Endoscopic assisted correction of square face / 中华医学美学美容杂志

Objective To evaluate the clinical application of endoscopic technique in corrections of square face. Methods A total of 38 patients (age 21~40 years, 35 women and 3 men) with square face were corrected by endoscope-assisted intraoral approach and resected mandibular angle with the high-speed pneumatic drill or bulky masseter muscle and buccal fat pad. Results The use of an endoscope offered a clear view of the mandibular angle region and the application of high-speed pneumatic drill facilitated accurate and easy resection of the the mandibular angle. These patients were successfully treated for these new techniques: ruduced surgical trauma, operative bleeding and surgical time, along with a reduced risk of infection. Conclusion The endoscopic assisted correction of square face offers more satisfactory clinical results with a clear view of operation and less haematoma, risk of infection, surgical trauma and time.

Square face deformity corrected by bilateral malar reduction and mandibualr angle osteotomy / 中华医学美学美容杂志

Objective To introduce a new method for correcting square face deformity.Methods This operation consists of malar reduction (MR)and mandibular angle osteotomy (MAO),which could be done simutaneously or at different time.Results A total of 21 patients with square face deformity accepted MR and MAO in which 12 cases were done simutaneously and 9 cases at different time.After this procedure, the width of the mid face and the lower face reduced by 15.3?3.2mm and 14.2?2.5mm, respectively. A11 the cases achieved satisfactory results without complications.Conclusion This method can effectively correct square face deformity by reducing the width and protrusion of the mid face and the width of the lower face.
