Repositioning the Posterior Septal Angle in Rhinoplasty: Methods and Outcomes.

Abstract

Objective: Repositioning and fixation of the posterior septal angle (PSA) relative to the anterior nasal spine (ANS) is a well-known maneuver performed during rhinoplasty. Suture techniques through the periosteum along with transosseous drilling through the spine are the two most common fixation methods. We report on how nasal airway patency varies as a function of technique and patient demographic factors.

Methods: A retrospective analysis was performed on patients who underwent PSA repositioning and stabilization during rhinoplasty due to caudal septal deformities. Nasal Obstruction Symptom Evaluation (NOSE) scales were measured pre- and post-operation to evaluate functional outcomes.

Results: 207 patients with either mobile or immobile PSA underwent ANS fixation secured with either a suture passed through the periosteum of the ANS or with the creation of a drill hole through the ANS. In all patients regardless of clinical or demographic groupings, postoperative NOSE scores were significantly decreased when compared to preoperative scores (p < 0.05). Preoperative NOSE score, fixation method, sex, functional versus cosmetic, age, follow-up period, and graft site did not independently affect the postoperative NOSE score. Though the differences between primary and revision outcomes were statistically significant, patients in both groups reported significant improvements in postoperative NOSE scores that deescalated their symptoms from "severe" to "mild."

Conclusion: Repositioning and fixation of the PSA improve patient outcomes. However, there is no significant difference between fixation methods on final NOSE scores. Septal fixation with consideration for patient anatomy allows for effective treatment.
