Nasal tip deprojection is a common goal in rhinoplasty. Several techniques have been described, many of which require destructive techniques that compromise the intrinsic integrity and morphology of the lateral crura. Through lateral translocation of the domes and shortening of the medial crura, nasal tip deprojection can be achieved without disrupting the integrity of the lateral crura. The domes are recreated lateral to the intrinsic domes with a standard transdomal suture, and excess length of the middle and medial crura is managed through transection and shortening of the medial crura. This technique preserves the morphology of the nasal base without altering the position of the medial crural footplates. Deprojection of 4 to 5 mm can be readily achieved with this technique.
鼻尖下垂是鼻整形术的常见目标。已经描述了几种技术，其中许多都需要破坏性技术，这会损害外侧脚的固有完整性和形态。通过外侧穹窿的横向移位和内侧脚的缩短，可以实现鼻尖下垂，而不会破坏外侧脚的完整性。通过标准的跨穹窿缝线在固有穹窿的外侧重新创建穹窿，通过切断和缩短内侧脚来处理中侧脚和内侧脚的多余长度。该技术在不改变内侧脚支撑板位置的情况下保持鼻基底的形态。通过这种技术可以很容易地实现 4 到 5 毫米的下垂。
