Application of a Modified Costal Cartilaginous Framework in Correction of Severe Saddle Nose Deformity.

Abstract

Insufficient support of the nasal septum due to congenital or secondary deficiency leads to severe saddle nose deformity, which presents an unpleasant appearance. The purpose of this study is to present our approach to constructing a costal cartilaginous framework with autologous costal cartilage for correction of severe saddle nose deformities. A retrospective analysis was conducted of patients who underwent correction of severe saddle nose deformity (type 2 to type 4) by a senior surgeon from January 2018 to January 2022. Preoperative and postoperative measurements were conducted to evaluate the surgical outcomes. A total of 41 patients ages 15 to 50 years completed the study. The average follow-up time was 20.6 months. No short-term complications were observed. Revisional operations were performed on 3 patients. All patients were satisfied with the aesthetic results. Analysis of objective measurements showed that the nasofrontal angle, columellar-labial angle, and tip projection improved significantly in type 2 cases, the nasofrontal angle and tip projection improved significantly in type 3 cases, and tip projection improved significantly in type 4 cases. Application of this modified costal cartilaginous framework, which consists of a fairly stable foundation layer and an aesthetic contour layer of block costal cartilage, has achieved satisfactory results over the long term.
