The purpose of this study was to analysis the nostril symmetry and nasal stability following secondary rhinoplasty performed with either nasal septal cartilage implantation (G1) or simple alar cartilage suspension and internal fixation (G2) in patients with unilateral secondary cleft nasal deformity.
Nostril and alar symmetry were analyzed retrospectively in 13 consecutive patients in G1 and 17 in G2. Assessment of three indexes was first performed using photogrammetric measurements of photographs at pre-operation(T1), 7 days after repair (T2), and at least 6 months after repair (T3). The ratio of the cleft side to the noncleft side for nostril width, nostril height and alar height were used to assess symmetry. Changes in the mean ratios of the cleft side to the noncleft side at three different time points for three parameters were used to assess stability.
In both groups, the alar height was improved after operation and remained stable in the follow-up period. The nostril width significantly decreased in G1 and G2, remaining consistent in the follow-up for G1 but increasing in G2. The nostril height significantly increased in G1 and stabilized during the follow-up, while it decreased after operation and remained so throughout the follow-up for G2.
Both techniques can maintain stability more than six months after surgery, except for the nostril width with simple alar cartilage suspension and internal fixation technique. The nasal septal cartilage implantation technique may have advantages in improving the nasal symmetry of the nostril width and height.
本研究旨在分析在单侧继发腭裂鼻畸形患者中,采用鼻中隔软骨植入术(G1组)或单纯鼻翼软骨悬吊内固定术(G2组)进行二期鼻整形术后的鼻孔对称性和鼻腔稳定性。
回顾性分析G1组连续13例患者和G2组17例患者的鼻孔及鼻翼对称性。首先,通过对术前(T1)、修复术后7天(T2)和修复术后至少6个月(T3)的照片进行摄影测量,评估三个指标。采用患侧与健侧鼻孔宽度、鼻孔高度和鼻翼高度的比值来评估对称性。使用三个参数在三个不同时间点患侧与健侧平均比值的变化来评估稳定性。
两组患者术后鼻翼高度均有改善,且在随访期内保持稳定。G1组和G2组的鼻孔宽度均显著减小,G1组在随访期间保持一致,而G2组则有所增加。G1组的鼻孔高度显著增加,并在随访期间保持稳定,而G2组术后降低,并在整个随访期间保持不变。
除单纯鼻翼软骨悬吊内固定技术的鼻孔宽度外,两种技术在术后六个月以上均能保持稳定性。鼻中隔软骨植入技术在改善鼻孔宽度和高度的鼻对称性方面可能具有优势。
