Spreader grafts are widely considered to be the mainstay of treatment for insufficient internal nasal valve and are commonly placed preventively during rhinoplasty, after hump removal, to avoid middle vault collapse. Although the placement and suturing of spreader grafts in open rhinoplasty is fairly easy, their positioning and stabilization in endonasal rhinoplasty is associated with a learning curve.
A review of the technique with tips for the novice surgeon is presented, particularly as pertains to correct placement. The technique can be used to insert spreader grafts irrespective of whether the nasal dorsum is addressed. Suturing is usually unnecessary. A retrospective review of 100 patients in whom spreader grafts were placed was undertaken to evaluate complications such as poor placement, displacement or other complications.
Although there is a learning curve to ensure the dorsal mucosal attachment is maintained while developing the pocket sufficiently dorsally for proper graft placement, the technique is easy to learn, effective, quick and technically simple to perform. Of 100 patients, three had a cartilaginous dorsal spur as the cephalic edge of the graft became visible. One patient developed an ecchymosis along the dorsum that caused a hump that resolved in two months. There were no other aesthetic or functional complications.
The endonasal placement technique provides for simple, safe and easy placement, as well as stabilization of spreader grafts during endonasal rhinoplasty, with few complications.
撑开移植物被广泛认为是治疗鼻内瓣膜功能不全的主要手段,并且在鼻整形术中,通常在去除鼻背驼峰后预防性地放置,以避免中鼻穹窿塌陷。尽管在开放式鼻整形术中放置和缝合撑开移植物相当容易,但在鼻内镜鼻整形术中其定位和固定存在学习曲线。
本文介绍了该技术并为新手外科医生提供了技巧,特别是关于正确放置的技巧。无论是否处理鼻背,该技术均可用于插入撑开移植物。通常无需缝合。对100例放置撑开移植物的患者进行回顾性研究,以评估诸如放置不当、移位或其他并发症等情况。
尽管存在学习曲线,即在充分向背侧形成用于正确植入移植物的腔隙时要确保维持背侧黏膜附着,但该技术易于学习、有效、快速且操作技术简单。100例患者中,3例在移植物头端边缘可见时出现软骨性鼻背棘。1例患者鼻背出现瘀斑,形成隆起,2个月后消退。无其他美学或功能并发症。
鼻内镜下放置技术在鼻内镜鼻整形术中能实现简单、安全且容易的放置以及撑开移植物的固定,并发症少。
