口内切口内窥镜直视下下颌角缩小整形术

Intraoral incision for mandibular angle reduction osteoplasty under endoscope

目的:口内切口下颌角整形由于切口和解剖结构的限制,手术视野和操作空间较为局限,我们希望借助内窥镜技术,来探寻一种直视下操作的下颌角整形手术方法。方法:采用全口内切口,内窥镜下设计画线,磨削减薄下颌骨外板、弧形切除肥大的下颌角、斜面修整下颌缘,在直视下使下颌骨三维立体缩小。结果:2005年以来,我们应用全口内切口入路内窥镜下下颌角缩小整形术256例,效果满意。结论:①全口内切口入路,体表不会遗留任何手术痕迹;②内窥镜下设计画线,准确对称;手术操作均在直视下进行,安全可靠;③手术采用弧形去除肥大的下颌角,使下颌角弧度自然完美;完整削薄下颌骨外板,使面部正面完整缩小;精细修整下颌缘,使整个下颌部位轮廓更加流畅柔美,从而面中下部位立体有效地缩窄。

Objective Due to structural limitations,surgical vision and operation of space is more limited,we hope that with endoscopic techniques to explore a kind of operating under direct vision method of mandibular angle plastic surgery though intraoral approach.Methods Design drawing lines,grinding thinning outer mandibular plates,curved hypertrophy of the mandibular angle resection and slope trimming marginal mandibular was employed for prominent mandibular angle though intraoral approach under endoscope so that the mandible in the three-dimensional reduced.Results Since 2005,256 cases whe were subject to prominent mandibular angle underwent curved mandible angle osteotomy though intraoral approach under endoscope.All cases gained more beautiful facial contour.Conclusion ① full-mouth incision into the road surface will not leave behind any traces of surgery.②endoscopic design drawing lines,accurate and symmetry;surgical operations were carried out under direct vision,safe and reliable.③surgical removal of hypertrophy of the jaw with curved angle,so that the natural curvature of the mandibular angle perfect;complete mandibular thinning outer plate so that the integrity of the front face reduced;fine finishing marginal mandibular,so that the entire lower jaw is more smooth contours of soft parts,which face the middle and lower parts of three-dimensional to effectively narrowed.
