The navel is an important cosmetic feature of the abdomen. A vertically long navel with a deep caudal side has recently been preferred by patients. Currently, there is no plastic surgery technique for complete umbilical repositioning or plasty after umbilical keloid resection. This study aimed to examine the effect of a new umbilicoplasty by combining a bilateral square flap with a triangular flap that utilizes the excess caudal skin nourished by the deep inferior epigastric artery perforator.
A total of 23 patients underwent umbilical keloid resection and new umbilicoplasty between April 2018 and March 2020. The mean patient age was 48.2 (range: 36-68) years, and mean body mass index was 23.1 (range: 18.5-33.4). Satisfaction with umbilical morphology was evaluated on a 5-point scale through interviews.
The surgery resulted in forming a vertically elongated deep caudal umbilical fossa. All patients were satisfied with their umbilical morphology (mean score, 4.6). In one case involving a woman who underwent breast reconstruction with a deep inferior epigastric artery perforator flap, superficial necrosis of the triangular flap was observed. However, no other complications were observed.
Creating a flap with stable blood circulation using the tissue originally excised during umbilical surgery allowed for the reproduction of a desirable umbilical morphology with adequate verticality and caudal depth.
肚脐是腹部重要的美学特征。患者近来更倾向于尾侧较深的垂直长肚脐。目前，尚无脐部瘢痕疙瘩切除术后进行完全脐部重新定位或整形的整形手术技术。本研究旨在探讨一种新的脐成形术的效果，该手术通过将双侧方形皮瓣与三角形皮瓣相结合，利用腹壁下动脉穿支滋养的多余尾侧皮肤。
2018年4月至2020年3月期间，共有23例患者接受了脐部瘢痕疙瘩切除术和新的脐成形术。患者平均年龄为48.2岁（范围：36 - 68岁），平均体重指数为23.1（范围：18.5 - 33.4）。通过访谈以5分制评估患者对脐部形态的满意度。
手术形成了垂直拉长且尾侧较深的脐窝。所有患者对其脐部形态均满意（平均评分4.6分）。在1例使用腹壁下动脉穿支皮瓣进行乳房重建的女性患者中，观察到三角形皮瓣浅表坏死。然而，未观察到其他并发症。
利用脐部手术中原先切除的组织创建具有稳定血液循环的皮瓣，能够重现具有足够垂直度和尾侧深度的理想脐部形态。
