Secondary cleft rhinoplasty is a challenge due to the complex anatomy of the nose, with structural deformity and difficulty in surgical management. This study aimed to evaluate the effect of an anatomical-based approach on enhancing tip and alar symmetry in secondary unilateral cleft rhinoplasty using photogrammetric evaluation.
The study was conducted on 57 adult patients seeking rhinoplasty after primary repair of congenital unilateral cleft lip deformity. All patients were operated upon using an external open rhinoplasty approach using an anatomical-based surgical technique. The cases were periodically followed up at three, six, 12 and 18 months for both aesthetic and functional outcomes with photogrammetric analysis of facial profile using the software Mirror Suite programme to compare before and after the surgical procedure.
The photogrammetric analysis showed a significant improvement of facial angles ( = 0.05). The nasofrontal angle changed from a median of 146° to 132.5°, nasolabial angle of 73° to 95°, nasofacial angle of 21.5° to 32° and nasomental angle of 105° to 130°. The rotation angle of the nasal tip showed a significant cephalic rotation with a mean increase of the tip elongation of 1.8 cm achieved per lateralised millimetre.
Secondary rhinoplasty in unilateral cleft deformities needs accurate evaluation of the anatomical and pathological abnormalities. Open approach is preferred with using costal cartilage graft allowing adequate columellar lengthening, maxillary enhancement and alar repositioning which leads to optimise the definition, projection and cephalic rotation with better stabilisation and symmetry of the nasal tip.
由于鼻子解剖结构复杂,存在结构畸形且手术管理困难,二期鼻整形术具有挑战性。本研究旨在通过摄影测量评估,评价基于解剖学的方法在二期单侧唇裂鼻整形术中增强鼻尖和鼻翼对称性的效果。
本研究对57例先天性单侧唇裂畸形一期修复后寻求鼻整形术的成年患者进行。所有患者均采用基于解剖学手术技术的开放式鼻整形术。通过使用Mirror Suite软件程序对面部轮廓进行摄影测量分析,对病例在术后3个月、6个月、12个月和18个月进行定期随访,以评估美学和功能结果,比较手术前后情况。
摄影测量分析显示面部角度有显著改善(P = 0.05)。鼻额角从中位数146°变为132.5°,鼻唇角从73°变为95°,鼻面角从21.5°变为32°,鼻颏角从105°变为130°。鼻尖旋转角度显示出明显的向上旋转,每向外侧移动1毫米,鼻尖伸长平均增加1.8厘米。
单侧唇裂畸形的二期鼻整形术需要准确评估解剖和病理异常情况。开放式手术方法更可取,使用肋软骨移植可实现充分的鼻小柱延长、上颌增强和鼻翼重新定位,从而优化鼻尖的清晰度、突出度和向上旋转,实现更好的稳定性和对称性。
