Application of the vacuum sealing drainage technique combined with skin flap in chronic ulcerative wounds / 中华整形外科杂志

<p><b>OBJECTIVE</b>To explore the feasibility and efficacy of the vacuum sealing drainage (VSD) technique combined with skin flap for the treatment of chronic ulcerative wounds.</p><p><b>METHODS</b>From June 2009 to Aug. 2011, the VSD technique combined with skin flap has been applied in the treatment of 15 patients with chronic ulcerative wounds caused by various reasons. The VSD was applied to the wound for 1-6 times. When infection was controlled and fresh granulation grew, skin flap was used to cover the wound.</p><p><b>RESULTS</b>Flap necrosis happened in a small area at the distal end in one case, which healed after skin graft. All the other flaps survived with primary healing. The patients were followed up for 6-24 months postoperatively with no recurrence of infection.</p><p><b>CONCLUSIONS</b>VSD combined with skin flap is an ideal choice for reconstruction of chronic ulcerative wounds. It has the advantages of low complications, reliable flap survival rate, and low infection recurrence.</p>

Repair of the large skin and vessel defect of upper arm with free anterolateral thigh flap / 中华整形外科杂志

<p><b>OBJECTIVE</b>To explore an effective method for repairing the large skin and vessel defect of upper arm.</p><p><b>METHODS</b>The large skin defect was repaired by the free anterolateral thigh flap. The vessel defect was reconstructed with the end branch of descending branch from lateral femoral circumflex artery, or the large muscular branch through bridge-like vascular anastomosis.</p><p><b>RESULTS</b>Since 2003, 5 cases were treated. All the flaps survived completely with a soft tissue texture. They were followed up for 8-24 months. The cosmetic and functional results were both satisfactory with less morbidity in the donor sites. The blood supply of the flap and the end of extremities was not affected by weather.</p><p><b>CONCLUSIONS</b>Anterolateral thigh flap is very suitable for large skin and vessel defect of upper arm.</p>

Therapeutic effect of dense-packing autologous hair grafting technique for restoration of seborrheic alopecia / 中华医学美学美容杂志

Objective To investigate the therapeutic effect of dense-packing auto hair grafting technique on the restoration of seborrheic alopecia. Methods With local anesthesia, a scalp strip was harvested from the back of the head. Under operating microscope (Various graft was created from the scalp strip, including micro-grafts with 1-2 hairs, mini-grafts with 3-4 hairs and sliver graft with 5-6 hairs. In the alopecia recipient area, micro slots were made with a small triangle-edged needle for the micro-grafts,mini slits were made with mini blade for the mini-grafts and foramen ovale were made with a slot punch. The grafts were then implanted into these holes. Results 32 cases of seborrheice alopecia were treated with the above mentioned technique from March 2007 to July 2009. Postoperative following up for 12-24 month showed that the grafted hairs were growing well with average 90 % survival of the hair. 81 % of the patients obtained satisfactory results with only one stage operation. Six patients needed the second operation to improve the appearance. All of the patients were satisfied with the appearance. Conclusions The dense-packing hair grafting technique with various grafts not only saves time of operation, but also obtains dense grafted hair and well appearance. The results are satisfactory to most patients with only one stage operation.
