延长前臂骨间背侧逆行皮瓣的一种方法

目的：提出一种延长骨间背侧逆行皮瓣和增加其可靠性的方法。方法：保留较多的皮肤穿支,将皮瓣包埋部分去表皮以保留真皮下血管网,从而提供皮瓣远端充足的血供以及静脉回流。结果：利用本方法修复掌指关节以远和掌侧缺损12例,皮瓣血运良好,无远端坏死。结论：本方法可增加皮瓣切取的长度,提高其可靠性,也可避免出现纵行瘢痕,为骨间背侧逆行皮瓣的应用提供了一种可选方法。     

Surgically-assisted maxillary expansion

A combined surgical and orthodontic technique for management of transverse maxillary deficiencies in mature patients is described and discussed. Special references are made to the surgical release of several circummaxillary articulations to facilitate the use of a fixed expansion device, and to the authors' addition of an osteotomy below the nasal spine, to ensure that the nasal septum remains independent of the maxillary segments. Indications for the use of this surgically-assisted maxillary expansion technique, and its advantages when compared with segmented surgical expansion, are also presented.     

组织扩张术皮肤胶原的代谢改变

目的：研究常规扩张（ＩＴＥ）和持续快速扩张（ＣＴＥ）对皮肤胶原代谢的影响。方法用白色小家猪制作组织扩张术动物模型，用Ｇｏｒｄｅｌａｄｚｅ法测定血清和扩张组织的羟脯氨酸（ＨＰ）含量，藻酸盐印模材膜片法测量标记区面积；光镜测量真皮厚度。结果：ＩＴＥ组血清ＨＰ含量升高，０．８倍，ＣＴＥ组升高１．２倍，ＩＴＥ和ＣＴＥ组皮肤含量与正常皮肤相同，组织中ＨＰ总量均明显升高，持续扩张皮瓣组（ＣＴＥＦ）术后４ｗｋ皮     

“Chain-link” combined tissue transfer for the reconstruction of the mandible

We describe a procedure for “chain-link” combined tissue transfer connecting the vascular pedicle of a deep circumflex iliac flap with that of a forearm flap after wide resection of the mandible. Combination of these flaps facilitated the reconstruction of the defect in both intra- and extraoral soft tissue and the mandibular bone. This method is useful when cervical recipient blood vessels are limited due to the wide resection of the primary tumor and radical neck dissection.     

带蒂胸腹轴型皮瓣早期修复上肢深度蛇伤溃疡

总结胸腹轴型皮瓣早期修复上肢不同部位的深度蛇伤溃疡的经验，评价其应用价值。本组１６例，胸脐皮瓣２例，侧胸腹皮瓣１例，髂腰皮瓣５例，下腹皮瓣６例，下腹分叶皮瓣１例，髂腰加下腹Ｙ形皮瓣１例。术后１例皮瓣远端坏死，３例轻度感染，１６例断蒂后全部成活。随访３个月～７年，皮瓣质地和弹性均好，手功能基本恢复。认为，带蒂胸腹轴型皮瓣是修复上肢深度蛇伤溃疡理想的方法。     

Modified Scleral Flap Incision to Reduce Corneal Astigmatism after Intraocular Lens Implantation

To investigate a simple method during extracapsular cataract extraction with posterior chamber intraocular lens implantation in order to reduce surgically induced corneal astigmatism.Methods: A modified scleral flap incision was used in the extracapsular cataract extraction with intraocular lens implantation and the postoperative changes in conreal astigmatism was observed.Results: The peak value of postoperative corneal astigmatism was 3. 60 D, and the corneal astigmatism regression was 2. 11 D, surgically induced astigmatism was less significant in modified scleral flap incision group than that in conventional limbal incison group (P<0. 05).Conclusions: The modified scleral flap incision is an ideal incision for cataract extraction with intraocular lens implantation when phacoemulsifier is not available.

真皮下血管网岛状皮瓣抗菌力的实验研究

为研究真皮下血管网薄皮瓣用于感染创面的可行性，在家猪臀部两侧分别形成以旋髂深血管主干分支为蒂的传统岛状皮瓣和远侧５０％修薄的真皮下血管网岛状皮瓣。用细菌计数、吖啶橙荧光染色测定白细胞吞噬指数和白细胞内杀菌率，应用激光多普勒、墨汁灌注、透明标本等方法，对两种皮瓣的抗菌力作自身对照研究。结果表明，真皮下血管网岛状皮瓣的抗菌力明显降低，可能与皮瓣修薄后血供减少，白细胞功能相应降低有关。     

地塞米松在大鼠缺血随意皮瓣中的作用

目的：研究局部使用地塞米松对大鼠缺血随意皮瓣的作用。方法：建立大鼠背部缺血随意皮瓣的动物模型，随机分为2组，实验组术后皮瓣下一次给予地塞米松5mg(用生理盐水稀释至3ml)，对照组术后皮瓣下一次给予0．9％生理盐水3ml。均于术后7d取材，测定皮瓣坏死率和组织中丙二醛含量，观察大体及病理切片。结果：实验组皮瓣坏死率和丙二醛含量较对照组显著降低(P＜0．01)。光镜下，实验组的炎性反应较对照组明显减轻。结论：地塞米松能提高缺血随意皮瓣的成活率，大剂量一次性给药的方法是可行的。     

颈阔肌肌皮瓣修复口腔癌术后组织缺损

目的探讨颈阔肌肌皮瓣修复口腔癌术后组织缺损的方法及可行性。方法2003年3月~2004年6月,应用颈阔肌肌皮瓣修复舌、口底、颊、咽侧壁及软腭缺损15例。其中男12例,女3例,年龄41~77岁。颊癌11例,舌癌1例,口底癌2例,咽侧壁及软腭癌1例。均行病变及颈淋巴根治性切除,缺损范围3.0 cm×3.5 cm~7.0 cm×4.0 cm,应用颈阔肌皮瓣修复软组织缺损,皮瓣范围7.0 cm×3.5 cm~12.0 cm×4.0 cm。结果术后15例皮瓣均成活,肌皮瓣色泽与皮肤相似,外形无异常,张口不受限。术后10~15 d出现颊部皮瘘8例,术后4周二期断蒂修补后完全愈合。随访6~12个月,无舌运动受限等并发症,肿瘤无复发,患者对术后形态及功能均较满意。结论颈阔肌肌皮瓣血运丰富,抗感染力较强,成活率高,是修复口腔组织缺损行之有效的方法,手术方法简便,值得推广。
