目的:评价牙列缺损、过小牙通过正畸修复联合治疗的临床疗效。方法:患者20例,牙列缺失12例,上颌侧切牙为过小牙8例。结果:通过适当的正畸手段,移动牙齿,为修复治疗提供最佳的牙列条件,已使患者得到最适当的治疗。结论:单纯的修复治疗只能顺其原来的错合状态进行义齿修复,对患者的口腔功能及美观没有产生实质性的改变。而根据合关系的需要进行正畸治疗,调整牙位,集中间隙,则有利于修复治疗,以达到符合生理状态的治疗效果。

目的研究膝关节镜下采用关节囊后内侧单向活瓣切除术治疗胭窝囊肿的临床疗效和术后并发症情况。方法回顾性研究2007年7月至2010年7月对因胴窝囊肿导致膝关节疼痛、活动受限的45例（45膝）患者采用关节镜下内侧关节囊活瓣切除术进行治疗，术中建立后内侧探查通道和囊肿切除工作通道，使用刨刀、等离子刀切除胭窝囊肿与后内侧关节囊单向交通的活瓣结构和囊肿内纤维分隔组织，同期对关节内合并的其他病变进行处理。在术前和随访时采用Rauschning和Lindgren评分标准进行评分，采用Wilcoxon秩和检验对评分结果进行统计学分析。结果45例患者中，40例患者合并关节内病变（88．9％），最为常见病变为内侧半月板撕裂27例（60．0％），其次为外侧半月板撕裂20例（44．4％）；关节软骨Ⅲ°-Ⅳ°损伤28例（62．2％），其中髌股关节软骨损伤12例（26．7％），股骨内髁软骨损伤10例（22．2％），股骨外髁软骨损伤6例（13．3％）。前交叉韧带损伤2例（4．4％）。随访时间13～51个月，平均（34±7）个月。所有患者术后膝关节后方不适症状明显缓解，Rausehning和Lindgren评分结果平均提升1～2级；术后末次随访时的Rauschning和Lindgren评分明显低于术前水平（Z=-6．092 P=0．00）。患者术后切口愈合良好，无切口感染及延迟愈合病例。1例患者术后2年复发，复发率为2．2％。随访期间无患者出现神经血管并发症，如隐神经、大隐静脉和胭血管损伤。结论关节镜下后内侧关节囊活瓣切除术治疗胭窝囊肿，微创、安全、有效、复发率低。可同期处理关节内并发的病变，手术效率高，近期临床疗效优良。
