摘要:
Objective To investigate the lifting effects by the application of an improved bidirectional trocar with U-shaped subcutaneous suture embedding in facial lift. Methods There were 37 patients with facial soft tissue laxity in this study. All patients utilized a self-made bidirectional trocar with PPDO (poly-para-dioxanone,PPDO) barbed suture that being used for the U-shaped embedding in subcutaneous tissue, the SMAS (superficial muscular aponeurotic system,SMAS) fascia tissue is lifted by the upper suspension to improve the relaxation of skin in the middle and lower face. The results were comprehensively evaluated according to the facial improvement before and after operation, post-operational healing,complications and patients' satisfaction. Results Facial relaxation gets improved significantly in all 37 patients who had received lifting surgery. In average 12 months follow-up, no serious complication such as hematoma, infection, nerve injury and so on was observed in the patients. The total effective rate was 100%, and the satisfaction rate for patients reached to 86.49%. Conclusion Compared with the current methods for facial lifting, our method possesses great advantages including high-level suspension, firm fixation, uniform distribution for suture embedding, large lifting range and strong lifting power, flexibility for adjusting suspension and so on. Therefore, it is worthwhile to apply this technique in facial lift widely.%目的:探讨应用改良双向套管针,以U形皮下埋线高位悬吊术行面部提升的临床效果.方法:本组37例面部皮肤软组织松弛患者,均采用自制的双向套管针,使用聚对二氧环己酮(poly-para-dioxanone,PPDO)锯齿状缝线在面部皮下作U形埋置,高位悬吊向上提拉表浅肌肉腱膜系统(superficial muscular aponeurotic system,SMAS)组织,对患者手术前、后面部松弛下垂改善程度、术后愈合情况、有无并发症及患者满意度进行综合评价.结果:本组37例患者术后即刻均可见面部松弛明显改善,术后平均随访12个月,未见患者有血肿、感染和神经损伤等并发症,总有效率为100%,患者满意率达86.49%.结论:双向套管针U形埋线高位提升术相较于目前同类面部埋线提升术,具有悬吊位置高、固定点牢固、埋线分布均匀、提升范围大、提升力强、可灵活调整等优势,适宜在临床中推广应用.
