Free tissue transfer at an army medical center

Free tissue transfer has been demonstrated to be an effective modality of treating a variety of wounds and conditions in the civilian population. The use of these procedures has been underreported by American military surgeons. Military surgeons face unique hurdles that make the effective performance of these procedures difficult. We report our experience with free flap reconstruction at an American Army medical center. We performed 44 free flaps in 38 patients; although operative times and hospital length of stay were comparatively long, our success rates were excellent with only one partial flap loss.

The remucosalizing alar cartilage flap: a reconstructive option for repairing nasal septal perforations

The objective of this study is to assess the results of repairing septal perforations with a vascularized pedicled alar cartilage island flap. Using the external rhinoplasty approach, a vascularized flap of alar cartilage, harvested as a cephalic trim and pedicled on the ascending columellar branches of the superior labial artery was raised. Bilateral mucoperichondrial septal flaps were elevated and the alar flap was transposed and secured within the defect and bilaterally overlaid with temporalis fascia. Silastic sheets were placed and remained in situ until the grafts were revascularized from the peripheries of the defect as well as centrally from the alar flap. The revascularized temporalis fascia acted as a scaffold for nasal remucosalization. The alar flap also increased the long-term structural robustness of the repair. Between 1999 and 2003, 14 patients with septal perforations ranging from 10 to 31 mm underwent septal reconstruction using this technique. There were nine males and five females. The flap was successfully raised in all cases and long-term closure was maintained in 12 patients (86%). The alar cartilage flap is an effective technique for repairing septal perforations in selected patients. It provides vascularized tissue which nourishes the grafts during remucosalization, and a cartilaginous framework, which affords long-term structural support to the repair. It also obviates the need to transpose nasal mucosa and create a secondary defect. The rhinoplasty approach furthermore permits additional nasal deformities to be corrected at the same time.

股前外侧区穿支动脉的形态学研究及皮瓣设计

目的探讨以旋股外侧动脉降支为蒂的皮瓣设计方法，以便增加术前多普勒定位的准确性。方法6具动脉灌注明胶-氧化铅混悬液的新鲜成人整尸标本，解剖观测股前外侧区穿支，通过血管造影术和拍摄X线片测量其直径、行程、分支和定位。用3D—doctor和Scion Image软件分别测量穿支供血的趋向性、三维重建和单穿支供血面积。结果股前外侧区共有外径大于0．5mm穿支16支，平均外径0．8mm，平均供血面积45．61cm^2，其中20％为肌间隙穿支，80％为肌皮穿支。平均蒂长为（3．15±1．43）cm。自旋股外侧动脉降支发出的穿支在浅筋膜中的平均长度为2．63cm。结论改良的氧化铅-明胶灌注技术可以为皮动脉和穿支皮瓣的研究提供高质量的血管造影图像。本研究发现股前外侧单穿支皮瓣的最大供血面积是30cm×20cm。以股前外侧区穿支设计的穿支皮瓣可以移植到下肢或身体其他部位。

“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.

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.
