双蒂额部扩张皮瓣修复颈部瘢痕挛缩畸形

Application of bi-pedicled frontal expanded flap for cervical cicatricial contracture

目的 探讨双蒂额部扩张皮瓣修复颈部瘢痕挛缩畸形的临床效果.方法 将扩张器埋置于额部额肌下,术后1周常规注水扩张.扩张完成后,根据颞浅动脉的走行设计双蒂皮瓣转移修复颈部创面.并对术前、后颈椎活动度和颏颈角进行测量,数据采用SPSS16.0统计学软件分析,并行t检验.结果 2006年9月至2010年5月,于临床应用7例,患者颈部主动活动度均得到不同程度改善,颈部前屈、后伸、左右侧屈及左右旋动度数均较术前增加,颏颈角术后测量为（90.7±2.2）°,较术前的（152.7±1.9）°明显改善,生理角度也得到恢复（P＜0.05）.术后随访5个月至3年,患者对治疗效果表示满意,瘢痕挛缩均无复发.结论 扩张后额部皮瓣血运可靠,可以较好地修复颈部挛缩瘢痕,功能和外形均能获得较满意的恢复,而且能很好地保留供区的形态和功能.

Objective To investigate the therapeutic effect of bi-pedicled frontal expanded flap for cervical cicatricial contracture. Methods Tissue expanders were implanted under frontal muscle. After expansion, the frontal flaps were designed based on bilateral superficial temporal vessels and were tranferred to the neck wound. The cervical spine movement and the mento-cervical angle was measured and analyzed by SPSS16. 0 and t test. Results From September 2006 to May 2010, 7 patients were treated by this method. The range of active cervical movement was improved in all direction. The mento-cervical angle decreased from （ 152. 7 ± 1.9 ） ° to （ 90. 7 ± 2. 2 ） ° after operation. The patients were followed up for 5months to 3 years with satisfactory result and no contracture recurrence. Conclusions The bi-pedicled expanded frontal flap has a reliable blood supply and is very suitable for cervical cicatricial contracture with good functional and esthetic results, leaving less morbidity at donor site.
