胫前动脉踝上穿支皮瓣修复足踝部软组织缺损19例

目的探讨胫前动脉踝上穿支皮瓣修复足踝部软组织缺损的临床疗效。方法回顾性研究2018年4月至2019年6月采用胫前动脉踝上穿支皮瓣修复足踝部软组织缺损19例的资料,其中男11例,女8例;年龄为21~75岁,平均39岁。根据前踝上穿支皮瓣解剖学基础,按照足踝部软组织缺损大小和形状,在小腿下端前外侧设计并切取皮瓣转位修复创面。切取胫前动脉踝上穿支皮瓣面积为6.0 cm×5.0 cm^14.0 cm×8.0 cm,均为带蒂皮瓣转位。根据皮瓣成活、感染控制、弹性色泽、外观形态、供区瘢痕、皮肤感觉、患者认可等情况,对患者足踝部软组织缺损的修复情况进行综合评价。结果本组19例皮瓣全部成活,软组织缺损、肌腱、骨质及钢板外露均得以修复。供区均I期愈合。术后门诊随访2~16个月,皮瓣血运良好,颜色接近周围正常皮肤,臃肿不明显,患者对外观表示满意;供区皮片愈合良好,无明显增生、挛缩及溃疡,踝关节功能良好。结论胫前动脉踝上穿支皮瓣是修复足踝部软组织缺损较为理想的方法之一,手术操作简便,穿支较恒定,血供可靠,具有一定的临床应用价值。     

Z形皮瓣及推进皮瓣修复眼睑缺损的作用探讨

目的探讨眼睑恶性肿瘤切除术中应用Z形皮瓣及推进皮瓣I期修复眼睑缺损的临床效果。方法将50例眼睑恶性肿瘤切除术患者按不同缝合方法分为两组,即对照组25例,术中直接缝合;观察组25例,术中行Z形皮瓣及推进皮瓣I期修复;比较两组眼睑修复效果。结果观察组术后皮瓣成活率96.0%、切口Ⅰ期愈合率100%、修复满意率92.0%,均高于对照组的72.0%、68.0%、56.0%,差异有统计学意义(P<0.05)。观察组术后并发症发生率低于对照组,但差异无统计学意义(P>0.05)。结论眼睑恶性肿瘤切除术中眼睑缺损修复时,采用Z形皮瓣及推进皮瓣,眼睑修复良好,患者修复满意率高,值得推广应用。     

A study for evaluating the effect of the deltoid-flap repair in massive rotator cuff defects

The repair of massive cuff defects by direct suture often is impossible. In these cases, a repair by musculo–tendineous flaps (latissimus-dorsi, pectoralis or deltoideus) is required. It was the goal of this study to evaluate the result of delta-flap repair in case of massive cuff defects with a diameter of 5 cm or more. Between 1998 and 2000 for all patients who were suffering from a massive rotator cuff tear more than 5 cm a deltoid transfer was performed. A total of 20 patients (14 male, 6 female; age: 60.9 ± 8.7 years) were available for a follow-up after 47.2 ± 8.0 (range, 36 to 60) month. The operation included an arthroscopic evaluation, acromioplasty with resection of the lateral clavicular end, and biceps tenodesis. The cuff defect was repaired by transfer a muscular flap from the anterior part of the deltoid (about 2×6 cm) into the defect. The patients subjectively rated their result—10 excellent, 9 good, and 1 poor. Preoperatively, the Constant amounted 26.3 ± 5.1 points. At follow-up, the score significantly increased to 74.5 ± 8.5 points. The acromiohumeral distance increased from 4.9 ± 1.1 to 9.2 ± 1.7 mm. In MRI examination of 11 patients all had an intact flap. Two complications (a wound hematoma and a deep infection) did not influence the result. The repair of massive rotator cuff tears by a deltoid transfer produces acceptable clinical and radiological results.     

颈肩背轴型反流皮瓣修复儿童颏颈瘢痕挛缩

目的探讨修复儿童颏颈瘢痕挛缩一种实用而较理想的方法.方法以颈横动脉浅支为蒂,利用其与旋肩胛动脉皮支的丰富吻合,反流形成超长的轴型皮瓣,向前旋转修复瘢痕松解后的颈前创面.结果采用本皮瓣修复30例儿童颏颈瘢痕挛缩,其中18例随访2年,颈部活动自如,颌骨发育无明显异常,皮瓣色泽良好,效果令人满意.结论本皮瓣轴型血管恒定,反流灌注动脉压高有保证,供瓣面积充足,供区多可直接拉拢缝合,是修复儿童颏颈瘢痕挛缩的较理想方法.     

Horizontal advancement flap for lateral dorsal nasal defects

BACKGROUND: Repairing dorsal nasal defects is a frequent challenge for dermatologic surgeons, mainly due to the high frequency of basal cell carcinomas on this site. Obvious scars, mismatched skin and distortion of the nasal contour are the surgical hazards that must be avoided in these cases. AIM: Our aim was to perform surgery involving a simple flap in order to repair medium to large defects on the dorsal side of the nose. METHODS: The dorsal horizontal advancement flap was studied in 12 patients, in order to evaluate the benefits and limits of this surgical procedure. RESULTS: The resulting scars on most of our patients were well-camouflaged among their natural skin lines, and there was neither distortion of the alar contour nor the nostril. CONCLUSIONS: This flap is easy to perform and, in selected cases, provides an outstanding alternative to second-intention healing, full-thickness skin grafts, transposition, rotation and pedicle flaps.     

游离空肠移植重建下咽颈段食管临床观察

目的:探讨游离空肠移植重建下咽颈段食管的可行性、技术操作方法及疗效。方法:回顾性分析采用游离空肠重建下咽颈段食管11例,其中喉癌术后复发1例,颈段食管癌2例,下咽癌8例。术中切除喉、下咽、颈段食管及部分颈段气管1例,切除喉、下咽及颈段食管8例,保留喉切除颈段食管2例。所有病例均给予颈淋巴清扫。术后放射治疗3例,剂量50~55Gy。结果:术后除1例移植肠管坏死改用前臂游离桡侧皮瓣卷成皮管移植重建外,其余10例均成活,成功率为90.9%。肠管成活病例中无咽瘘、感染等并发症发生,随访3~27个月,喉癌术后复发患者1例术后2个月肿瘤再发,出现吞咽梗阻。结论:游离空肠移植重建下咽颈段食管手术成功率高,恢复消化道的连续性安全可靠,内侧为黏膜的空肠瓣是下咽颈段食管极好的修复材料。     

游离腓骨皮瓣移植Ⅰ期修复胫骨创伤性骨髓炎骨皮缺损
