应用小阴唇扩张皮瓣的阴道形成术

目的　探索应用软组织扩张器扩张小阴唇组织 ,以小阴唇扩张皮瓣行阴道形成术的方法。方法　选择 3cm× 5cm、5 0ml肾形扩张器 ,置入小阴唇内外侧壁之间及阴唇间沟 ,扩张小阴唇 ,以获取足够面积的小阴唇组织。于尿道膀胱与直肠间造穴 ,翻转蒂在阴唇后联合处的小阴唇双叶皮瓣 ,以小阴唇皮瓣衬覆阴道腔壁 ,完成阴道形成术 ;术后夜间佩带模具 3～ 6个月。结果　本组5例经术后 6个月～ 2年随访 ,4例已结婚 ,性生活满意 ;外阴形态正常 ,再造阴道外口大于 2横指 ,深度≥ 8cm ,具有感觉和分泌功能 ,接近生理需要。结论　应用软组织扩张器扩张小阴唇形成阴道是诸多阴道形成术中较为理想的方法 ,其损伤小 ,并发症少 ,再造阴道接近解剖及生理状态。

Labia minora skin flap vaginoplasty using tissue expansion

ObjectiveThis is to introduce a method for vagina reconstruction using the expanded labia minora flap. Methods Two tissue expanders were implanted in the labia minora bilaterally and expanded slowly over 4 weeks. In the operation, the expanded labial tissue was advanced as a bipedicle flap to line the reconstructed vagina. Five patients were treated with this method. Postoperative stent placement and dilation resulted in a vaginal canal exceeding 8 cm in depth. Results During the follow-up of 6 months to 2 years, four of the five patients got married. The vulva exhibited almost indistinguishable appearance. The reconstructed vagina had sensory and secretary functions. Its morphology and depth well meet the physiological demand. ConclusionsThe modified method of tissue expansion vaginoplasty using the labia minora bipedicle flap is a good option for vagina surgery. The reconstructed vagina possesses the anatomical and physiological resemblance. ;
