摘要

背景:各种阴茎成形术已被报道;然而,尚未达成共识。因此,考虑到影响皮瓣选择的因素,我们建议一个理想的阴茎成形术的替代算法。方法回顾性分析32例变性人阴茎成形术。将用于阴茎成形术的皮瓣分为三组:(1)前臂桡侧(RF)组,(2)大腿前外侧(ALT)组,(3)皮瓣组合(FC)组。统计分析年龄、体重指数(BMI)、术后并发症发生率、再手术率、审美可接受性、触觉或性感敏感性、站立排尿能力的差异。结果RF组10例,ALT组7例,FC组15例。BMI方面,RF组(mean [standard deviation (SD)] = 25.9[3.3])的BMI明显高于ALT组(21.7[0.9])或FC组(22.2[4.5])。RF组(mean [SD] = 3.7[0.4])和ALT组(mean [SD] = 3.5[0.9])的审美可接受性评价得分(1 ~ 4分)明显高于FC组(2.5[1.2])。此外,RF和ALT组在触觉和性感敏感性方面优于FC组。结论BMI与皮肤厚度相关,影响阴茎成形术皮瓣的选择。在基于BMI的皮瓣选择方面,FC成为ALT皮瓣和RF皮瓣之间的一种选择。我们基于BMI的理想阴茎成形术的替代算法将有助于客观皮瓣的选择。

Flap Selection Algorithm Based on the Body Mass Index for Phalloplasty in Female-to-Male Transgender: Techniques and Outcomes
Abstract Background Various phalloplasty methods have been reported; however, a consensus has not been reached. Therefore, we suggest an alternative algorithm for an ideal phalloplasty considering the factors that affect flap selection. Methods We retrospectively examined 32 phalloplasty cases of female-to-male transgender. Flaps used for phalloplasty were classified into three groups as follows: (1) radial forearm (RF) group, (2) anterolateral thigh (ALT) group, and (3) flap combination (FC) group. Statistical analyses were performed to determine the significance of age and body mass index (BMI) as well as differences in the rates of postoperative complication, reoperation, esthetic acceptability, tactile or erogenous sensibility, and the ability to urinate while standing. Results Ten cases were included in the RF group and 7 and 15 cases in the ALT and FC groups, respectively. With respect to BMI, the RF group (mean [standard deviation (SD)] = 25.9 [3.3]) showed significantly higher BMI than the ALT (21.7 [0.9]) or FC group (22.2 [4.5]). The RF (mean [SD] = 3.7 [0.4]) and ALT groups (3.5 [0.9]) had significantly higher esthetic acceptability evaluation scores (from 1 to 4) than the FC group (2.5 [1.2]). Moreover, the RF and ALT groups were superior than the FC group in terms of tactile or erogenous sensibility rates. Conclusion BMI effected flap choices for phalloplasty because of the correlation between BMI and skin thickness. FC becomes an option between ALT flap and RF flap in terms of flap choice based on BMI. Our alternative algorithm for an ideal phalloplasty based on BMI will be useful for objective flap choices.
