A multivariate analysis after preservation rhinoplasty (PR) - a prospective study.

Abstract

Preservation rhinoplasty (PR) is considered to be an innovative approach with high patient satisfaction. However, little is known about its functional outcomes and radiological analyses. In this prospective clinical study, 30 patients (20 female and 10 male patients, mean age 30.7 ±9.8 years) were operated on between 2017 and 2021. Radiological assessment was evaluated by cone beam computed tomography before surgery and at final follow-up. Patient assessment regarding their outcome was assessed at final follow-up using a validated questionnaire (rhinoplasty outcomes evaluation questionnaire = ROE). After a mean follow-up of 8.4 ± 5 months (range = 1 - 18 months), radiological analyses denoted an overall improved internal nasal valve (INV) angle after surgery (preoperative = 20.77° ± 3.2° vs. postoperative = 21.82° ± 5.7°, p = 0.18). Those results are in accordance with an overall high patient satisfaction for both function and aesthetics (ROE score 18.4 ± 4.3). Our study showed a preserved and widened INV angle after PR, along with high patient satisfaction. III.
