31例眼睑恶性肿瘤切除后Ⅰ期修复的总结

眼睑恶性肿瘤切除术后,眼睑修复时机的选择,对保持眼睑功能和美容的效果起着十分重要的作用,术式的选择是决定手术成功关键。采用眼睑全层缺损行异体巩膜片移植,替代睑板、滑行球结膜瓣前徙替代睑结膜的眼睑再造术,对31例眼睑恶性肿瘤切除,同时进行眼睑再造术。术后无排斥反应,眼睑闭合良好,外形满意。结论认为,较大范围的眼睑恶性肿瘤切除的患者,采用异体巩膜片移植、滑行结膜瓣前徙眼睑再造术能达到保持眼睑功能和美容的效果,是理想的眼睑恶性肿瘤切除后Ⅰ期修复临床决策。     

鼻烟窝皮瓣修复拇指大面积皮肤缺损的临床应用

探讨鼻烟窝皮瓣在修复拇指大面积皮肤缺损中的方法和治疗效果。从2008年1月～2013年10月间应用桡动脉在解剖鼻烟窝穿支为血管蒂的鼻烟窝皮瓣,逆行修复拇指大面积皮肤缺损26例,年龄17岁～55岁。术后平均随访时间25个月,皮瓣全部成活。皮瓣色泽及质地与健侧拇指背侧皮肤相近,拇指活动度基本正常。因此,鼻烟窝皮瓣是一种简便经济、效果理想、患者易于接受的术式,适合应用于拇指大面积皮肤缺损的治疗。     

双血供胸大肌皮瓣修补咽颈部缺损

探讨双血供胸大肌皮瓣修补咽颈部缺损的可行性。介绍应用双血供胸大肌皮瓣修补咽颈部缺损36例,窄蒂胸大肌皮瓣修补咽颈部缺损7例。结果前者愈合23例,出血3例,感染5例,咽瘘5例,皮瓣坏死无;后者愈合2例,出血1例,感染1例,咽瘘2例,皮瓣坏死1例。双血供胸大肌皮瓣修补咽颈部缺损更利于术后愈合、预防咽瘘。

Vaginoplasty in Male to Female Transsexuals Using Penile Skin and Urethral Flap

ABSTRACT.

Objectives: Vaginoplasty presents the main problem in male to female surgery. There are many operative techniques that can be used, but none is ideal. We present our one stage vaginoplasty in male to female sex reassignment surgery.

Patients and Methods: The principle of our technique is based on penile disassembly and usage of all penile entities for vaginoplasty except corpora cavernosa. We developed our disassembly technique on a very large number of severe hypospadias reconstruction and adrenogenital “conversions.” Penile skin flaps and urethral work are used in each of these. Our new vagina consists of two parts: a long vascularized urethral flap and a pedicled island tube skin flap created from the penile skin. The urethral flap is embedded into the skin tube. The tube, consisting of skin and urethral flap, is inverted, thus forming the new vagina. The new vagina is inserted into the previously prepared perineal cavity between the urethra, bladder, and rectum. The new vagina is fixed to the sacrospinous ligament. The labia minora and majora are formed from the remaining penile and scrotal skin.

Results: The follow-up ranged from 3 months to 6 years (mean 4.6 years). Good cosmetic and functional results were obtained in 77 out of 89 patients (87%).

Conclusions: The technique provides results that have the most normal anatomical and physiological characteristics, in comparison to other methods, since all penile entities are used (except corpora cavernosa) to form almost normal external female genitalia. Vaginoplasty using pedicled penile skin with a urethral flap could be a very good alternative to other methods of vaginoplasty.
