Abstract
in English, Chinese

Objectives: This study aimed to compare the impacts of undertaking symmetrical bone repair of the nasal alar base combined with nasolabial deformity repair versus nasolabial deformity repair alone on the improvement in nasal deformity of patients with unilateral cleft lip and alveolar cleft.

Methods: Fifty patients presenting with unilateral cleft lip and alveolar cleft were evaluated. Among them, 20 underwent nasolabial deformity repair solely (non-bone grafting group), whereas 30 patients received bone repair in conjunction with nasolabial deformity repair (bone-repair group). Preoperative measurements and one-year follow-up results were assessed through photographic anthropometric analysis. According to the Farkas anthropometric standard, the nasal anatomic landmarks were located, and 10 nostril indicators were measured. The operative effects of two groups were compared.

Results: In contrast to the non-bone-grafting group, the nasal deformity of patients in the bone-repair group demonstrated significant improvement one year post-operation. The symmetry parameters of the nasal columella more closely approximated 1, the columella deviation angle more closely approached 90°, and the sub-alare inclination angle and the inclination angle of the nasal alar were smaller (P<0.05).

Conclusions: The accomplishment of symmetrical bone repair of the nasal alar base is conducive to enhancing nasal deformity after cleft-lip surgery in patients with unilateral cleft lip and alveolar cleft. This strategy has a positive influence on nasal symmetry, the morphology of the nasal alar, and nasal base deformity.

目的: 比较鼻翼基底对称性骨修复联合鼻唇畸形整复术与仅行鼻唇畸形整复术对单侧唇裂伴牙槽突裂患者鼻畸形的改善效果。方法: 研究共纳入50例单侧唇裂伴牙槽突裂患者，其中20例仅行鼻唇畸形整复术（不植骨组），30例行骨修复联合鼻唇畸形整复术（骨修复组）。收集患者术前、术后1年面部观照片，参照Farkas人体测量学标准，进行鼻部解剖标志点的定位，测量10个鼻畸形指标，比较2组的手术效果。结果: 与不植骨组相比，骨修复组患者术后1年的鼻畸形获得了明显改善，其中鼻小柱对称参数更接近1，鼻小柱倾斜角更接近90°，鼻翼基脚内倾角及鼻翼基底倾斜角更小（P<0.05）。结论: 鼻翼基底对称性骨修复有助于改善单侧唇裂伴牙槽突裂患者唇裂术后鼻畸形，对鼻部对称性、鼻翼形态及鼻底畸形的改善效果明显。.
