Many Asian patients with nasal aesthetic surgery desire a sharper, more defined nasal tip. In many cases, their nasal cartilage is not abundant enough, necessitating cartilage transplantation from an extranasal location. We investigated which patients would qualify for a method of reshaping the nasal tip without needing donor cartilage by reshaping the lower cartilage using the transdomal suture technique and local cartilage grafting.
We performed a single-center retrospective cohort study of patients undergoing nasal tip surgery. We divided patients into two groups. Group 1 comprised 13 patients with nasal tips with thin skin and soft tissue and relatively abundant cartilage. Group 2 included 31 patients with nasal tips with thicker, firmer skin and soft tissue and a smaller amount of cartilage. No patients had prior nasal surgery, and all patients were followed up for at least 3 months. Patients in both groups underwent the transdomal suture technique and local cartilage grafting. Five patients in Group 2 underwent alar reduction. Preoperative and postoperative lateral view photographs were superimposed and analyzed to measure changes in tip projection.
Patients in Group 1 showed a mean increase in tip projection of 3.9%. Patients in Group 2 demonstrated a mean decrease in tip projection of -1.5% without alar reduction and -5.6% with alar reduction.
If the nasal tip is predominantly cartilaginous, patients may undergo surgery that does not involve donor cartilage from another site with good results. However, most patients, who have a relatively small amount of nasal tip cartilage, are not good candidates for this procedure.
许多接受鼻部美容手术的亚洲患者希望拥有更尖挺、更有型的鼻尖。在很多情况下,他们的鼻软骨量不足,需要从鼻外部位移植软骨。我们研究了哪些患者通过使用跨穹窿缝合技术重塑下部软骨和局部软骨移植,有资格在无需供体软骨的情况下进行鼻尖重塑手术。
我们对接受鼻尖手术的患者进行了单中心回顾性队列研究。我们将患者分为两组。第1组包括13例鼻尖皮肤和软组织薄但软骨相对丰富的患者。第2组包括31例鼻尖皮肤和软组织更厚、更硬且软骨量较少的患者。所有患者均未接受过鼻部手术,且均接受了至少3个月的随访。两组患者均接受了跨穹窿缝合技术和局部软骨移植。第2组中有5例患者接受了鼻翼缩小术。对术前和术后的侧位照片进行叠加分析,以测量鼻尖突出度的变化。
第1组患者的鼻尖突出度平均增加了3.9%。第2组患者在未进行鼻翼缩小术时鼻尖突出度平均下降了-1.5%,在进行鼻翼缩小术后下降了-5.6%。
如果鼻尖主要由软骨构成,患者可以接受不涉及从其他部位获取供体软骨的手术,且效果良好。然而,大多数鼻尖软骨量相对较少的患者并不适合这种手术。
