Optimal timing for cleft lip rhinoplasty is controversial. Definitive rhinoplasty is deferred until facial skeletal growth is completed. Intermediate rhinoplasty is performed after stabilization of the grafted alveolar bone, because the grafted bone tends to be absorbed over several months postoperatively, distorting the nasal profile. Here, we report our experience with simultaneous rhinoplasty during alveolar bone grafting for indicated patients, describe our surgical technique that ensures long-term bone graft survival, and report graft take rates and nasal profile changes.
This retrospective chart review included a total of 54 patients; 44 underwent alveolar bone grafting only, and 10 underwent simultaneous cleft lip rhinoplasty. All surgeries were conducted with a judicious mucosal incision for tensionless wound closure. Bone graft take was evaluated with dental radiographs by the Bergland classification. Further, nasal aesthetic outcome was evaluated with medical photographs, based on nostril height and width and alar base width.
In total, 96.3% of clefts showed graft success with Type I (66.7%) or Type II (27.8%) classifications; only 3.7% of clefts showed unfavorable results classified as Type III, and no clefts showed Type IV failure. The nasal shape was flatter with a decreased nostril height and increased nostril width after alveolar bone grafting, while nostril height was increased and nostril width was decreased in patients who underwent simultaneous rhinoplasty.
With surgical techniques ensuring alveolar bone graft survival, simultaneous cleft lip rhinoplasty can result in nasal aesthetic improvement for patients with severe nasal deformities, decreasing the number of operations.
唇裂鼻整形术的最佳时机存在争议。确定性鼻整形术会推迟到面部骨骼生长完成之后。中期鼻整形术在移植的牙槽骨稳定后进行,因为移植骨在术后几个月往往会被吸收,从而扭曲鼻外形。在此,我们报告为特定患者在牙槽骨移植期间同时进行鼻整形术的经验,描述确保移植骨长期存活的手术技术,并报告移植成功率和鼻外形变化。
这项回顾性病历审查共纳入54例患者;44例仅接受牙槽骨移植,10例同时接受唇裂鼻整形术。所有手术均采用明智的黏膜切口以实现无张力伤口闭合。通过牙科X线片根据伯格伦德分类法评估移植骨的成功情况。此外,基于鼻孔高度和宽度以及鼻翼基底宽度,通过医学照片评估鼻部美学效果。
总体而言,96.3%的腭裂显示移植成功,分类为I型(66.7%)或II型(27.8%);仅3.7%的腭裂显示分类为III型的不良结果,没有腭裂显示IV型失败。牙槽骨移植后鼻形更扁平,鼻孔高度降低,鼻孔宽度增加,而同时进行鼻整形术的患者鼻孔高度增加,鼻孔宽度减小。
通过确保牙槽骨移植存活的手术技术,同时进行唇裂鼻整形术可改善严重鼻畸形患者的鼻部美学效果,减少手术次数。
