目的 研究负压引流对扩张皮瓣血液循环的影响,以指导临床在耳廓再造中合理有效使用负压引流技术.方法 将21例耳廓再造患者随机分为A、B、C 3组,分别给予-20、-40和-60 kPa负压引流,并于术后即刻、5和10 d分别测量计算3组患者再造耳廓的长、宽之差值,以间接了解再造耳廓肿胀和皮瓣静脉回流情况.术后采用红外热像仪检测再造耳廓于0、-20、-40和-60 kPa负压下皮瓣近(耳甲腔)、远端(耳轮缘)的温度变化.结果 B组术后5d再造耳廓的长、宽差值分别为(1.48±0.47) mm和(0.36±0.06) mm,明显小于术后即刻的(1.67±0.69) mm和(0.40±0.16) mm;A、C组也有差别,但并无统计学意义(P>0.05).B组术后10 d再造耳廓的长、宽差值分别为(1.31 ±0.42) mm和(0.48±0.04)mm,与术后5d比较,差异有统计学意义(P<0.01);而A、C2组比较,差异无统计学意义.再造耳廓皮瓣肿胀程度随负压值增大,呈现先下降后增加的趋势(P<0.01);扩张器自体肋软骨耳廓再造术负压引流强度在0~60 kPa范围内,随负压强度增大,再造耳廓皮瓣温度升高(P<0.01);且近端温度的增加大于远端,差异有统计学意义(P<0.01).结论 负压引流对再造耳廓皮瓣静脉回流及动脉供血均有影响,-40 kPa负压对再造耳廓动脉供血及静脉回流均有促进作用,可为临床设定负压引流强度提供参考.  相似文献

The main goal, in eyelid reconstruction, is to promote an adequate protection to the ocular globe, through the reconstitution of all anatomic plans. In order to obtain adequate stability, cartilage grafts are often used in the repair of the internal lamella. Cartilage grafts from auricular scapha in contact with the bulbar conjunctiva were used in this study. Nineteen patients with various pathologies had 20 eyelid reconstructions using this technique (10 cutaneous tumors, 7 post-traumatic, and 3 cases of lower eyelid retraction). Local cutaneous flaps (glabella, Mustardè, etc) were used to reconstruct the external lamella. Epithelialization on the perichondrium (confirmed by the histological examination) occurs between 3 to 4 weeks. The functional and aesthetic result was considered good in 14 cases (70%), acceptable in 5 (25%) and poor in one case (5%). The donor area showed no complications or deformities. The shape of the scapha allows satisfactory conformation of the graft to the curvature of the ocular globe; it is not flat like the nasal septum, and has a smoother curvature than the auricular concha. Furthermore, it is thinner and that is another reason why the aesthetic result was superior to the technique previously used. The functional results were similar.

The authors emphasize the recent advances in breast reconstruction provided by use of the skin expander device. A Silastic percutaneous skin expander developed by the authors and the Dow Corning Corporation has been used by them in breast reconstruction for the past 7 years with satisfactory results. Important design differences in the device suggested by the authors include the use of a reinforced backing which consists of Dacron Silastic sheeting extending beyond the inflatable teardrop-shaped envelope for approximately 3/8 of an inch, thus adding strength and rigidity to the envelope and the rim, and making it possible for the rim of the expander implant to be sutured in an appropriate orientation.  相似文献

A 20-year-old male who sustained a severe avulsion injury of his left scalp and face together with a cranial bone fracture on his right temple six years previously, presented with extensive alopecia over the left temporal scalp. There was also a depression in the right temple with complex scarring caused by previous operations. A simultaneous complete reconstruction of the scalp defect and the depression was obtained by expansion of the left temporoparietal scalp, followed by free-flap transfer of the expanded tissue and augmentation with a free scapular flap. The end result was very satisfactory.  相似文献

The cheek and nose are common areas for skin cancers. There are multiple approaches to surgical excision and reconstruction, depending on the size of defect, tissue quality, adjacent cosmetic units and hairline. An effective solution to skin defects of the lateral cheek is the bilobed flap. This flap tends to be underused in the lateral cheek area because primary closure and skin grafts are perceived to be easier methods of reconstruction. However, the use of the bilobed flap for lateral cheek and other defect closures is encouraged. There are several basic principles that are key when performing this flap. These components of the procedure are highlighted.  相似文献

Reconstruction of partial defects of the Hypopharynx and Cervical esophagus following resection for locally advanced carcinoma, by pectoralis major myocutanous flap (PMMF) was studied in 30 consecutive cases over a period of 5 years from 1988–1992 at the Tata Memorial Hospital. Patients with circumferential excisions were excluded for the purpose of this study. Two patients died in the post-operative period due to massive upper GI haemorrhage and cerebrovascular accident. These 2 patients were excluded from further analysis. Satisfactory oral intake was achieved in 26 (85%) patients. Pharyngocutanous fistula (PCF) developed in 10 (29%) patients. Anastomotic strictures developed in 4 patients, out of 2 were benign and 2 were due to recurrence of disease. Median hospital stay in patients who developed PCF was 39 days as against 14 days in those who did not develop PCF. With a minimum follow up of two years 47% patients are dead of disease, 32% are lost to follow and only 14% are alive and free of disease. Statistical analysis using univariate and multivariate tests failed to reveal any significant predisposing risk factors for PCF. Patch PMMF for the reconstruction of partial defects of the hypopharynx is a safe and reliable procedure.  相似文献

Objective

The choice between local flap designs for burn reconstruction is largely shaped by aesthetic, vascularity, procedural complexity, and wound-closure considerations. However, another key consideration is how well specific local flap designs release post-burn scar contractures. This is because constant tension on wound edges can generate pathological scarring. However, the ability of specific local flap to release post-burn scar contractures is poorly understood. This question was addressed by this study of patients who underwent local flap surgery to release post-burn scar contractures.

Methods

The flap type, its original size, and the degree to which the flap extended 6 months after surgery were recorded.

Results

Of the 40 patients enrolled, 20 received an island flap and 20 received a skin-pedicled flap. The scars were most commonly located on the anterior chest, axilla, and cubital fossa, followed by the lateral chest, abdomen, thigh, and popliteal fossa. Six months after surgery, the skin-pedicled and island flaps had extended on average by 1.53- and 1.28-fold, respectively.

Conclusions

While it was technically easier to transfer island flaps to the recipient site, they released contractures less effectively than skin-pedicled flaps. The postoperative extensibility of flaps should be considered when determining which flap design is optimal for the individual patient.  相似文献

Background:

Fingertip defect can be treated with many flaps such as random pattern abdominal flap, retrograde digital artery island flap, V-Y advancement flap, etc. However, swelling in the fingertip, dysfunction of sensation, flexion and extension contracture or injury in the hemi-artery of the finger usually occurs during the recovery phase. Recently, digital artery perforator flaps have been used for fingertip reconstructions. With the development of super microsurgery techniques, free flaps can be more effective for sensory recovery and durability of the fingertip.

Materials and Methods:

Six cases (six fingers) of fingertip defects were treated with free digital artery perforator flaps of appropriate size and shape from the proximal phalanx. During surgery, the superficial veins at the edge of flap were used as reflux vessels and the branches of the intrinsic nerve and dorsal digital nerve toward the flap were used as sensory nerves. The proximal segment of the digital artery (cutaneous branches) towards the flap was cut off to form the pedicled free flap. The fingertips were reconstructed with the free flap by anastomosing the cutaneous branches of digital artery in the flap with the distal branch or trunk of the digital artery, the flap nerve with the nerve stump and the veins of the flap with the digital artery accompanying veins or the superficial veins in the recipient site.

Results:

Six flaps survived with successful skin grafting. Patients were followed up for 6-9 months. The appearance and texture of the flaps was satisfactory. The feeling within the six fingers recovered to S4 level (BMRC scale) and the two point discrimination was 3-8 mm.

Conclusion:

Free digital artery perforator flap is suitable for repairing fingertip defect, with good texture, fine fingertip sensation and without sacrificing the branch of the digital artery or nerve.  相似文献
