The Effectiveness of the Cartilaginous Push-Down Dorsal Preservation Technique in the Correction of I- and C-Shaped Crooked Nose Deformities

Key Points

Evaluate the effectiveness of the cartilaginous push-down dorsal preservation technique for nasal deviation correction.
Analyzed 48 female patients undergoing closed cartilaginous push-down rhinoplasty.
Measured preoperative and postoperative nasal deviation angles.
Utilized standardized digital image analysis for comparison.
I-shaped deformities showed improvement from 6.5 ± 2.4° to 0.1 ± 0.3° (p < 0.001).
C-shaped deformities improved from 167.1 ± 5.3° to 179.4 ± 0.7° (p < 0.001).
Significant corrections in nasal axis deviation were achieved.

Abstract

Objective: This study aimed to evaluate the effectiveness of the cartilaginous push-down dorsal preservation rhinoplasty technique in correcting postoperative nasal axis deviation in patients with I- and C-shaped crooked-nose deformities.Methods:Forty-eight female patients undergoing closed cartilaginous push-down rhinoplasty were included. Preoperative and 12-month postoperative nasal deviation angles were measured using standardized digital image analysis and compared statistically.Results: Significant improvement was obtained with the applied method.In I-shaped deformities, deviation improved from 6.5 ± 2.4° to 0.1 ± 0.3° (p 0.001). In C-shaped deformities, deviation improved from 167.1 ± 5.3° to 179.4 ± 0.7° (p 0.001).Conclusion: The cartilaginous push-down dorsal preservation technique is effective in correcting I- and C-shaped crooked nose deformities while preserving dorsal continuity and structural integrity.
