Radiological and Anatomical Parameters as Determinants of Success in Dorsal Preservation Rhinoplasty.

[BACKGROUND] Rhinoplasty is a common cosmetic and functional procedure that aims to enhance nasal aesthetics and airway function. Dorsal preservation rhinoplasty (DPR) is increasingly favored for its ability to preserve the natural anatomy of the nose while minimizing complications. This study sought to identify ideal candidates for DPR by analyzing anatomical parameters that affect surgical outcomes.

[OBJECTIVES] The aim of this study was to determine the suitability of patients for dorsal preservation surgery through preoperative radiological measurements.

[METHODS] A prospective observational study was conducted in the otorhinolaryngology department of a tertiary hospital, involving 43 patients undergoing high-strip dorsal preservation rhinoplasty. Preoperative and intraoperative CT scans were performed to assess nasal anatomy, focusing on features like nasal bone length, radix root to nasal tip distance, and the kyphion angle. The overall surgical success (OSS) score was utilized to measure outcomes, calculated by subtracting complications, reoperations, and hospitalizations from a base score of 10.

[RESULTS] The cohort included 43 patients (6 males, 37 females), with a mean age of 26.4. Intraoperative data revealed that 55.8% required hump rasping and 27.9% had residual humps at 6 months. Positive correlation was found between longer radix root to nasal bone tip distances and lower OSS scores (r = 0.31, P = .043). Shorter nasal bones were associated with higher OSS scores (r = -0.45, P = .002), and larger kyphion angles correlated with lower success rates (r = -0.30, P = .049).

[CONCLUSIONS] Shorter nasal bones and lower kyphion angles are associated with better outcomes in dorsal preservation rhinoplasty. Tailoring surgical techniques to individual anatomical features can improve both aesthetic and functional results, enhancing patient satisfaction.
