摘要
目的通过比较三种方法处理后的咬肌厚度的变化,评价不同方法在减小咬肌厚度中的应用价值。方法对单纯下颌角截骨术患者5例,下颌角截骨术+咬肌部分切除术患者4例,下颌角截骨术+咬肌注射A型肉毒毒素患者4例,应用B超对患者手术前后12、24周咬肌厚度进行测量,比较其术后咬肌厚度减小程度。结果单纯下颌角截骨术、下颌角截骨术+咬肌部分切除术及下颌角截骨术+咬肌注射A型肉毒毒素组于术后12周咬肌厚度平均减少(4.876±5.270)%,(32.939±2.900)%,(14.006±4.866)%;术后24周分别减少(2.637±4.806)%,(30.286±3.644)%,(36.878±4.702)%。结论从远期效果观察,下颌角截骨联合咬肌注射A型肉毒毒素与下颌角截骨联合咬肌部分切除或单纯下颌角截骨手术比较,能更有效地减少咬肌厚度。
Objective To evaluate the effects of reducting the thickness of masseter muscle with three different treatments on masseteric hypertrophy therapy. Methods Five female patients who took mandibular angle osteotomy operation （MAO）, four female who took mandibular angle osteotomy operation and partial muscle resection （MAO ＋ MR） and other four female who took mandibular angle osteotomy operation and botulinum toxin type A injection （ MAO ＋ BI） were enrolled in this study. The thickness of masseter muscles was measured at 12 and 24 weeks postoperatively using B- ultrasound respectively and compared preoperatively. Results The reduction of masseter muscles thickness at 12 weeks postoperative of MAO, MAO ＋ MR and MAO＋BI was （4.876±5.270）%, （32.939±2.900）% and （14.006±4.866）%, respectively. Itwas （2. 637 ± 4. 806） %, （30. 286 ± 3. 644） % and （36. 878 ± 4. 702） % at 24 weeks respectively. Conclusion The effect of MAO＋ BI on thickness reduction of masseter muscle was much more than that of MAO＋ MR or MAO on long- term view.
