Alar rim deformities such as retraction, notching, collapse, and asymmetry are common problems in rhinoplasty patients. Although alar rim deformities may be improved through rhinoplasty, this area is prone to late changes because of scarring of the soft triangles and a paucity of native structural support. The purpose of this study was to analyze the effect of alar contour grafts on primary rhinoplasty.
Fifty consecutive primary rhinoplasty patients with preoperative and postoperative photographs who received alar contour grafts were evaluated for alar aesthetics; 50 consecutive primary rhinoplasty patients without such grafts served as controls. Differences among alar retraction, notching, collapse, and asymmetry from anterior, lateral, and basal views were evaluated. Follow-up ranged from 1 to 4 years and was graded on a four-point scale.
The average difference between the two groups' aggregate preoperative scores was 0.21 (p = 0.24). The average preoperative and postoperative scores in the nongraft group were significant for worsening retraction, notching, and collapse but insignificant for asymmetry. The preoperative and postoperative scores for the graft group were insignificant for retraction but improved significantly for notching, collapse, and asymmetry. Postoperatively, the aggregate average of the scores in the nongroup was 0.32 points worse (p < 0.01), whereas the graft group had a 0.33-point improvement (p < 0.01).
Alar contour grafts have a clear and important impact on cosmetic results of primary rhinoplasty. Use of alar contour grafts has been shown to improve aesthetics, whereas there is a worsening of the measured parameters postoperatively without use of these grafts.
CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
鼻翼边缘畸形,如退缩、切迹、塌陷和不对称,是隆鼻患者常见的问题。尽管鼻翼边缘畸形可通过隆鼻术得到改善,但由于软三角区的瘢痕形成和缺乏天然结构支撑,该区域容易出现后期变化。本研究的目的是分析鼻翼轮廓移植对初次隆鼻术的效果。
对连续50例接受鼻翼轮廓移植的初次隆鼻患者进行术前和术后照片拍摄,评估鼻翼美观度;连续50例未进行此类移植的初次隆鼻患者作为对照。从正面、侧面和底面观察评估鼻翼退缩、切迹、塌陷和不对称的差异。随访时间为1至4年,并采用四点量表进行评分。
两组术前总评分的平均差异为0.21(p = 0.24)。非移植组术前和术后评分在退缩、切迹和塌陷方面显著恶化,但在不对称方面不显著。移植组术前和术后评分在退缩方面不显著,但在切迹、塌陷和不对称方面有显著改善。术后,非移植组评分的总平均值差0.32分(p < 0.01),而移植组有0.33分的改善(p < 0.01)。
鼻翼轮廓移植对初次隆鼻术的美容效果有明显且重要的影响。已证明使用鼻翼轮廓移植可改善美观度,而不使用这些移植时术后测量参数会恶化。
