Inconsistent and suboptimal outcomes in secondary cleft lip deformity repairs stem from the absence of a standardized classification system for nasolabial deformities, causing surgeons to rely heavily on their experience to determine surgical strategies. Nasal sill morphology reflects the severity of nasolabial deformities and plays a crucial role in facial aesthetics. This study introduces a novel classification for secondary cleft nasolabial deformities based on nasal sill morphology from the base view and provides tailored surgical techniques for each type.
The study included 276 patients who underwent secondary cleft nasolabial correction at Peking University Third Hospital between August 2019 and July 2024. Patients were categorized according to the novel classification system and received surgeries tailored to their specific deformity type.
Among the 276 patients, 13 (4.71%) were categorized as type I, 25 (9.06%) as type II, 73 (26.45%) as type III, and 165 (59.78%) as type IV. All patients achieved improved nasal sill aesthetics and enhanced nasal symmetry.
This novel classification system, based on nasal sill morphology, accurately characterizes secondary nasolabial deformities and offers a structured approach for surgeons to tailor surgical strategies to each patient's deformity type. The present study tries to help establish an objective standard for secondary surgery of cleft nasolabial deformity for the first time.

二期唇裂畸形修复效果不一致且不理想，原因在于缺乏针对鼻唇畸形的标准化分类系统，这使得外科医生在很大程度上依赖经验来确定手术策略。鼻槛形态反映了鼻唇畸形的严重程度，对面部美学起着关键作用。本研究基于鼻槛从基底部视角的形态，引入了一种针对二期唇裂鼻唇畸形的新分类方法，并为每种类型提供了针对性的手术技术。
本研究纳入了2019年8月至2024年7月期间在北京大学第三医院接受二期唇裂鼻唇矫正的276例患者。根据新的分类系统对患者进行分类，并根据其特定的畸形类型进行手术。
在276例患者中，13例（4.71%）被归类为I型，25例（9.06%）为II型，73例（26.45%）为III型，165例（59.78%）为IV型。所有患者的鼻槛美学均得到改善，鼻对称性增强。
这种基于鼻槛形态的新分类系统准确地描述了二期鼻唇畸形，并为外科医生根据每个患者的畸形类型量身定制手术策略提供了一种结构化方法。本研究首次尝试帮助建立唇裂鼻唇畸形二期手术的客观标准。
