摘要
【目的】探讨双侧鼻唇沟轴型带蒂肌皮瓣修复口底大面积缺损后皮瓣生长变化及对供区的影响。【方法】对12例口底癌根治术后口底大面积缺损（缺损面积3．5～5．0×5．0～8．0cm^2）患者应用双侧鼻唇沟轴型带蒂肌皮瓣行Ⅰ期修复，随访12—60个月，观察皮瓣成活和生长状况，评价供区疤痕对面容的影响。【结果】12例患者修复后均Ⅰ期愈合。术后1个月，皮瓣上皮开始软化，3个月后上皮角质层部分脱落，术后1年，接近口腔粘膜；供区术后3个月内疤痕突出，影响面容，3个月后面部皮肤逐渐松弛，术后1年供区疤痕已接近双侧鼻唇沟，在年长患者更为明显。【结论】双侧鼻唇沟轴型带蒂肌皮瓣与口底缺损区邻近，皮瓣面积较大，易成活，为口底癌根治术后口底大面积缺损修复提供了一种可靠的选择，尤其适用于年长患者。
[Objective ] To assess the efficacy of bilateral axial pedicle nasolabial myocutancous flaps which were used to repair the large area of defect in oral floor and the influence of them on donor sites. [Methods]Twelve patients with oral floor cancer underwent radical resection and the large area of intraoral defects [（3.5-5.0） × （5.0- 8.0 cm^2）] were repaired with bilateral axial pedicle nasolabial myocutancous flaps at the same time. The patients were followed up for 12-60 months after operation to evaluate the survival of the flaps and changes of scars in donor sites. [Results] All the myocutancous flaps survived smoothly after operations. The flap began to soft after one month and part of the epithelia stratum corneum fell after 3 months. About one year late the scar in donor site came close to nasolabial crease in face, specially in aged patient. [Conclusion] Bilateral axial pedicle nasolabial myocutancous flaps are close to the floor of mouth with good blood supply and cover enough tissue to repair the large area of defect in oral floor caused by radical resection of oral floor cancer. These flaps are particularly suitable to the aged patient.
