The release of wide burn contractures leads to defects that cannot be closed with local flaps. In these cases, tissue expansion of local tissues may be a solution. However, when local tissues are also burned, distant tissue transfer remains the only option. Tissue expanded anterolateral thigh (ALT) flaps can be a reasonable option.
A 15-year-old boy with a cervical burn contracture had limited movement in the neck. The release of the contracture and removal of the scarred tissue resulted in a 22 × 18-cm neck defect. This was resurfaced with preexpanded anterolateral thigh perforator flap.
Three months postoperatively, the flap shrunk to the point that the underlying aesthetic anatomical landmarks such as the clavicle, sternal notch, sternocleidomastoid muscle, and thyroid cartilage were clearly visible. The reconstruction was both functionally and cosmetically excellent.
Tissue expanded ALT can be a good option in wide burn contractures where local tissues are inadequate. The advantages are (1) large flaps can be prepared without any functional loss, (2) the expanded skin thins making it more cosmetically appropriate to resurface skin only defect, and (3) the donor area stays under the clothes during expansion period and is well tolerated by the patient.
广泛烧伤挛缩的松解会导致局部皮瓣无法修复缺损。在此类情况下,局部组织扩张可能是一种解决方案。然而,当局部组织也受到烧伤时,远处组织转移仍是唯一选择。组织扩张的股前外侧(ALT)皮瓣可能是一个合理的选择。
一名15岁患有颈部烧伤挛缩的男孩颈部活动受限。挛缩松解及瘢痕组织切除后,颈部出现一个22×18厘米的缺损。采用预扩张的股前外侧穿支皮瓣进行修复。
术后三个月,皮瓣收缩至锁骨、胸骨切迹、胸锁乳突肌和甲状软骨等美学解剖标志清晰可见。重建在功能和美观方面均效果极佳。
在局部组织不足的广泛烧伤挛缩中,组织扩张的ALT皮瓣可能是一个不错的选择。其优点包括:(1)可制备大皮瓣且无任何功能损失;(2)扩张后的皮肤变薄,更适合仅修复皮肤缺损,美观效果更佳;(3)扩张期间供区位于衣物下方,患者耐受性良好。
