摘要目的 报告应用掌背侧菱形推进皮瓣重建指蹼治疗先天性并指畸形的疗效.方法 对5例先天性并指畸形患儿,分指后在患指掌背侧掌骨头间设计并切取掌背侧菱形推进皮瓣以重建指蹼.术后评价指标包括:手指功能情况,指蹼形态学观察和患儿家长的满意度.结果 皮瓣切取面积最大为2.0cm×0.9cm,最小1.5cm×0.6cm.术后所有皮瓣愈合良好,未出现淤血、边缘坏死等现象.术后随访时间为6～12个月,平均8.5个月,患指屈伸功能良好,重建指蹼深度、宽度合适,并形成较好的指蹼坡度,患儿家长对指蹼形态及术后手指功能均感满意.结论 在治疗先天性皮肤性并指分指术中,应用背侧菱形推进皮瓣重建指蹼,术式简单,外形美观,是一种理想的方法.

abstractsObjective To report the clinical outcomes of reconstructing the web with dorsal metacarpal rhombus advancement flap in the treatment of syndactyly. Methods Five children with syndactyly were operated. After the digits were divided, a dorsal rhombus flap was designed between the metacarpal heads and advanced to reconstruct the web space. The following aspects were evaluated during postoperaive follow-up:finger function, web space and appearance, and patients' satisfaction. Results The area of flaps ranged from 1.5 cm× 0.6 cm to 2.0 cm× 0.9 cm. All the flaps healed primarily without flap congestion and marginal necrosis. The patients were follow-up for 6 to 12 months with an average of 8.5 months. Finger flexion and extension was good. The contour of the web was satisfactory with appropriate width and depth. The patients' parents were satisfied with both finger function and web appearance. Conclusion Dorsal metacarpal rhombus advancement flap is a reliable flap with easy dissection and good texture for web reconstruction in syndactyly surgery.
