概括

技术因素,而不是解剖学,是防止"坏分裂"的关键在下斜骨骨切除术期间. 精确的外科手术技术至关重要,以尽量减少 orthognathic 手术中的并发症.

科学领域:

口腔和牙面部外科手术
整形手术整形手术整形手术
手术并发症手术并发症

背景情况:

"坏分裂" (Bad Split,BS) 是一个在下斜骨切除术期间发生的手术内并发症.
了解它的流行病学和风险因素对于改善外科手术结果至关重要.

研究的目的:

在下斜骨骨切除术期间分析"坏分裂" (BS) 的发生率和特征.
确定与BS发生相关的解剖学和技术风险因素.

主要方法:

五年来对157名患者 (314例骨切除术) 的回顾性分析.
对手术前后的CT扫描进行评估,以分类BS和评估风险因素.
分析解剖学变量 (例如,第三,骨尺寸) 和技术骨切除术的执行.

主要成果:

在BS的发病率为3.2%,左侧占主导地位.
最常见的是A类BS (近端段的远端骨折).
先前位置的舌头和下膜脊被认为是解剖学因素;骨切除术执行的偏差,特别是不完整的基底骨切除术,是重要的技术因素.

结论:

在BS发生时,技术因素,特别是骨切除术执行精度,比解剖学变量更为关键.
尽量减少BS风险需要细致的外科手术技术,特别是在具有易受解剖特征的下中.
强调了手术技巧在整形手术过程中的重要性,以避免手术内并发症.

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
