Clinical and 3-Dimensional Analyses of Nasal Forms After Secondary Correction of Cleft Lip-Nose Deformities Using Extended Spreader Cartilage Graft With a Cross-Lap Joint Technique

摘要

Purpose: A surgical strategy for definitive cleft lip-nasal correction that stably provides symmetric and natural nasal forms has not been established to date. The purpose of this study was to describe our surgical techniques and 3-dimensional (3D) assessment results after the definitive correction of cleft lip-nose deformity using an extended spreader cartilage graft with a cross-lap joint technique to achieve a rigid strut for lower lateral cartilage repositioning to obtain a desirable nasal tip projection.
