Bilateral masseter muscle hypertrophy is an alteration in shape and thickness of the masseter muscles that can modify the width of the lower face causing aesthetic and functional problems. A 21-year-old man was referred to the Department of Maxillofacial Surgery at the Civil Hospital in Brescia by his dentist for an evaluation of his facial appearance with a square-face type. To reduce the undesirable facial appearance, a surgical intraoral approach was performed; the procedure includes the bilateral dissection of the masseter muscle, partial lipectomy, and the ostectomy of the mandibular angle assisted by a surgical guide built on a stereolithographic model. The patient was satisfied with the functional and aesthetic outcomes of both the profile and the frontal views. There was no evidence of complication at a 1-year follow-up. This new method yields optimal aesthetic results with an enhanced outline of the lower face.
双侧咬肌肥大是咬肌形状和厚度的改变，可改变下脸宽度，导致美学和功能问题。一名21岁男性被其牙医转诊至布雷西亚市民医院颌面外科，以评估其方形脸的面部外观。为改善不理想的面部外观，采用了手术口内入路；该手术包括双侧咬肌剥离、部分脂肪切除术以及在基于立体光刻模型制作的手术导板辅助下进行下颌角截骨术。患者对侧面和正面观的功能及美学效果均感到满意。1年随访时无并发症迹象。这种新方法能产生最佳美学效果，使下脸轮廓更清晰。
