Preservation rhinoplasty: evaluating the effects of cephalic resection on nasal anatomical angles in primary open rhinoplasty

Preservation rhinoplasty focuses on maintaining the physiological anatomy of the nose. Preserving the physiological angles between the upper and lower cartilages is important for minimizing complications and achieving satisfactory outcomes in rhinoplasty procedures.

In this study, 42 candidates (23 females and 19 males) undergoing elective primary open rhinoplasty in Shiraz between 2020 and 2021 were included prospectively in a single-center hospital. The mean patient`s age was 26.2 \(\:\:\pm\:\:\) 5.2, and they were between 18 and 40 years old. The angle of divergence, resting angle, and angle between the border of the upper lateral cartilage (ULC) and the lower lateral cartilage (LLC) were measured before and after cephalic resection.

The study found a significant increase in the border angle of ULC and LLC, and the angle of divergence, the resting angle following cephalic resection. The mean angle of divergence increased from 78.0952 ± 29.15711 to 80.1426 ± 26.73590 degrees. The resting angle increased from 115.9762 ± 17.99931 to 119.038 ± 25.38592 degrees. The border angle of ULC and LLC increased from 39.8571 ± 14.38592 to 40.3095 ± 14.10844 degrees. The level of cephalic resection measured 5.4524 ± 1.29167.

These findings indicate that cephalic resection of LLC has a significant impact on the anatomical nasal angles. Surgeons should consider the amount of cephalic resection and its effects on these angles to optimize patient satisfaction in terms of both function and aesthetics.
