A new operative technique is described in which the natural curved nasal dorsum is retained in a modified fashion. Specifically, the nasal dorsum is elevated, the nasal height is reduced, and then the newly designed roof is lowered. Based on a minimum 1-year follow-up of 14 patients and a total experience of 28 patients, the procedure has the following advantages: (1) near normal anatomic structure is retained, (2) common secondary dorsal deformities are avoided, (3) the retained roof can function as a spreader graft, (4) the skin attachment with its attendant blood supply is preserved, and (5) the graft can be removed primarily or easily modified secondarily. Disadvantages appear to be the need for greater finesse and a limited follow-up of 2 years.
本文描述了一种新的手术技术，即采用改良方式保留自然弯曲的鼻背。具体而言，先抬高鼻背，降低鼻高，然后降低新设计的鼻顶。基于对14例患者至少1年的随访以及28例患者的总体经验，该手术具有以下优点：（1）保留接近正常的解剖结构；（2）避免常见的继发性鼻背畸形；（3）保留的鼻顶可起到鼻小柱支撑移植物的作用；（4）保留皮肤及其伴随的血供；（5）移植物可一期取出或二期轻松修改。缺点似乎是需要更高的技巧以及仅2年的有限随访。
