Outcome Evaluation of Using Bone-Cartilaginous Units to Correct Deviated Noses in Rhinoplasty

Background: Aesthetic and functional problems related to a deviated nose are challenging to correct with rhinoplasty. Objective: To compare the outcome of rhinoplasty using nasal septal bone-cartilaginous units (BCUs) as measured by pre- and postoperative patient-reported outcomes and photograph analysis. Methods: A retrospective chart review was conducted on rhinoplasty patients who had BCU placed between February 2018 and March 2021. Three-dimensional photographic measurements were assessed before and at least 1 year after surgery using Mirror software. Data on patient satisfaction were collected by the Nasal Obstruction Symptom Evaluation (NOSE) and the Rhinoplasty Outcomes Evaluation (ROE) questionnaires. Statistical analysis was completed with independent t-tests and Wilcoxon signed-rank test. Results: Twenty-eight patients were enrolled with a mean age of 34.52 ± 13.7 years (range 20-77 years) and mostly female (61%). The degree of nasal deviation (from 1/82° ± 1/52° to 0/13° ± 0/45°) and the width of the middle nasal third to palpebral fissure length (from 1/28° ± 0/18° to 1/19° ± 0/19°) significantly changed (p-value <0.001). NOSE and ROE scores also improved significantly postoperation (p-value <0.001). Conclusion: The bone-cartilaginous unit graft was effective in rhinoplasty for nasal deviations and may be considered an option.
