A split ostectomy of mandibular body and angle reduction.

摘要: Combined mandibular angle resection with angle-splitting ostectomy (ASO) is more effective than conventional simple or multistaged ostectomy. Removal of the outer cortex body by ASO lessens protuberance masseter muscle. In this study, anatomy canals in seven human cadavers was studied detail, and a guideline for set up so as to avoid injury inferior alveolar nerve. The most vulnerable area nerve line from gonion (G) junction (O) intersecting vertical along anterior border ramus horizontal on crest because thin distance (AD) between buccal surface mandible wall canal. should not be above 17.5 mm at GO ensure safe distance, floor canal (21.6 +/- 4.1 mm). less relatively thicker AD second molar (8.3 mm) first (6.8 Pilot surgery performed five cadavers. lateral safely split off, avoiding nerve, then done. This method applied two clinical cases without any complications. "split reduction" new
