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

Abstract

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

Objectives: Aim of this study was to determine the suitability of patients for dorsum 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 used to assess nasal anatomy, focusing on features like nasal bone length, radix root-to-nasal tip distance, and Kyphion angle. The Overall Surgical Success score was used 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 X ± Y. Intraoperative data revealed that 55.8% required hump rasping, and 27.9% had residual humps at six months.Positive correlation was found between longer radix root-to-nasal bone tip distances and lower OSS scores (r=0.31, p=0.043). Shorter nasal bones were associated with higher OSS scores (r=-0.45, p=0.002), while larger Kyphion angles correlated with lower success rates (r=-0.30, p=0.049).

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.
