微型骨凿在口腔外科手术中应用体会

Clinical New Understanding about Narrow Bone Chisel Used In Ora Surgery

目的对比两种骨凿的使用特点和患者接受程度。方法136名研究对象，男性病人78例，女性58例，随机接微型窄和普通宽骨凿进行操作。研究组在窄骨凿去骨术中，利用其窄刃和锐薄的特点，使用一般宽骨凿的敲击力度1／4即可断裂骨皮质；对照组取常规力度和方法使用完成断离去骨、切削铲除、挤入扩展等操作。结果震动感、操作控制性、和助手间接感知三项指标，微型骨凿与普通骨凿相比较有统计学差异（P〈0．05）。结论微型骨凿在实现精细操作方面有独到之处，其在轻敲力度下实现切割更给患者体现人文关怀。
