Free-tissue transfer has become the accepted standard for reconstruction of complex defects. With the growth of this field, anatomic studies and clinical work have added many flaps to the armamentarium of the microvascular surgeon. Further advancements and experience with techniques of perforator flap surgery have allowed for the harvest of flaps in a free-style manner, where a flap is harvested based only on the preoperative knowledge of Doppler signals present in a specific region. Between June of 2002 and September of 2003, 13 free-style free flaps were harvested from the region of the thigh. All patients presented with an oral or pharyngeal cancer and underwent resection and immediate reconstruction of these flaps. All flaps were cutaneous and were harvested in a suprafascial plane. The average size of the flaps was 108 cm2 (range, 36 to 187 cm2), and the average length of the vascular pedicle was 10 cm (range, 9 to 12 cm). All flaps were successful in achieving wound coverage and functional outcomes without any vascular compromise necessitating re-exploration. Free-style free flaps have become a clinical reality. The concepts and techniques used to harvest a free-style free flap will aid in dealing with anatomic variations that are encountered during conventional flap harvest. Future trends in flap selection will focus mainly on choosing tissue with appropriate texture, thickness, and pliability to match requirements at the recipient site while minimizing donor-site morbidity.
游离组织移植已成为复杂缺损修复的公认标准。随着该领域的发展,解剖学研究和临床工作为微血管外科医生的技术储备增添了许多皮瓣。穿支皮瓣手术技术的进一步进步和经验积累,使得皮瓣可以采用一种自由式的方式切取,即仅根据术前对特定区域存在的多普勒信号的了解来切取皮瓣。在2002年6月至2003年9月期间,从大腿区域切取了13例自由式游离皮瓣。所有患者均患有口腔或咽癌,并接受了肿瘤切除及皮瓣即刻修复。所有皮瓣均为皮肤皮瓣,在筋膜上平面切取。皮瓣平均面积为108平方厘米(范围为36至187平方厘米),血管蒂平均长度为10厘米(范围为9至12厘米)。所有皮瓣均成功实现了创面覆盖且功能良好,未出现任何需要再次探查的血管并发症。自由式游离皮瓣已成为临床现实。用于切取自由式游离皮瓣的概念和技术将有助于应对传统皮瓣切取过程中遇到的解剖变异。未来皮瓣选择的趋势将主要集中在选择质地、厚度和柔韧性合适的组织,以匹配受区需求,同时尽量减少供区并发症。
