Rhinoplasty started as a closed technique and then the open technique gained popularity. Open technique gave surgeons the opportunity to visualize and manipulate the cartilaginous skeleton at the tip of the nose precisely. The dissection planes in open rhinoplasty technique may be subcutaneous, submuscular (under the superficial musculoaponeurotic system), or subpericondrial subperiosteal. Each plane has advantages and disadvantages. The aim of this study was to combine planes to get the maximal benefit of each plane.
The study was performed on 38 Middle Eastern patients, among whom 23 were females and 15 were males. All patients presented for primary rhinoplasty. They were divided into 5 groups on the basis of their skin thickness. Dissection started subcutaneous at the area of the lower lateral cartilages and then shifted subsuperficial musculoaponeurotic system over the upper lateral cartilages and ended subperiosteal over the bony skeleton.
This triple plane of dissection gave acceptable results without any complication. Subcutaneous dissection allowed thinning of the thick sebaceous skin at the tip and alar region, subsuperficial musculoaponeurotic system dissection allowed direct exposure of the upper lateral cartilage without thinning skin at an area where it is thin, and subperiosteal dissection helped masking any bony irregularities resulted from osteotomies.
The triple plane dissection in open primary rhinoplasty in Middle Eastern patients maximized the advantages of each plane and minimized the disadvantages and resulted in safe cosmetic results.
隆鼻手术最初是一种闭合技术,随后开放技术开始流行。开放技术使外科医生有机会精确地可视化和操作鼻尖的软骨支架。开放隆鼻技术中的解剖层面可以是皮下、肌下(在表浅肌肉腱膜系统之下)或软骨膜下骨膜下。每个层面都有优缺点。本研究的目的是将各层面结合起来,以获得每个层面的最大益处。
该研究对38名中东患者进行,其中女性23名,男性15名。所有患者均接受初次隆鼻手术。根据皮肤厚度将他们分为5组。解剖从下外侧软骨区域的皮下开始,然后在上外侧软骨上方转移至表浅肌肉腱膜系统下,最后在骨支架上方止于骨膜下。
这种三重解剖层面产生了可接受的结果,且无任何并发症。皮下解剖可使鼻尖和鼻翼区域的厚皮脂性皮肤变薄,表浅肌肉腱膜系统下解剖可直接暴露上外侧软骨,而不会使该区域薄皮肤变薄,骨膜下解剖有助于掩盖截骨术导致的任何骨质不规则。
中东患者开放初次隆鼻手术中的三重层面解剖最大化了每个层面的优点,最小化了缺点,并产生了安全的美容效果。
