Reconstruction of lower lip defects is challenging because of the functional and aesthetic demands of the lower face. We review the functional and aesthetic outcomes of the Karapandzic-type flaps for reconstructing lower lip defects.
A retrospective review of patients who underwent repair using Karapandzic-type flaps.
Fifty patients with lower lip defects ranging from 20% to 95% (mean 59.2% ± 20%) were included. Eighteen patients (36%) were repaired using a bilateral flap, and 32 (64%) were reconstructed using a unilateral flap design. All patients had preservation of oral competency and a satisfactory aesthetic result. No patient complained of microstomia. A complication rate of 8% was noted ( n = 4) with postoperative wound infection and small areas of dehiscence. There was no statistically significant difference in complication rates in patients older than 75 years, in patients with a history of head/neck radiation, or in defects greater than 70% of lower lip breadth.
Karapandzic-type flaps are versatile and reliable for the reconstruction of a broad range of lower lip defects. This one-stage procedure can produce superior functional and aesthetic results as compared with other local and distant flaps with minimal risk of functional microstomia.
由于下脸部的功能和美学需求，下唇缺损的重建具有挑战性。我们回顾了用于重建下唇缺损的卡拉潘迪奇（Karapandzic）式皮瓣的功能和美学效果。
对接受卡拉潘迪奇式皮瓣修复的患者进行回顾性研究。
纳入了50例下唇缺损范围为20%至95%（平均59.2%±20%）的患者。18例（36%）患者采用双侧皮瓣修复，32例（64%）采用单侧皮瓣设计重建。所有患者均保留了口腔功能，美学效果满意。没有患者抱怨小口畸形。观察到并发症发生率为8%（n = 4），包括术后伤口感染和小面积裂开。75岁以上患者、有头颈部放疗史的患者或下唇宽度缺损大于70%的患者，其并发症发生率无统计学显著差异。
卡拉潘迪奇式皮瓣对于重建各种下唇缺损具有通用性和可靠性。与其他局部和远处皮瓣相比，这种一期手术可以产生更好的功能和美学效果，且功能性小口畸形风险最小。
