Objectives. A crooked nose is frequently caused by nasal bony vault deviation, and proper management of the bony vaultis an integral part of rhinoplasty. Conventional osteotomy to correct a deviated nose favors simultaneous medial andlateral osteotomies, which allows the free independent movement of each nasal bone. However, patient satisfactionwith deviated nose surgery is sometimes low. In the present study, we introduce a one-unit osteotomy procedure thatcombines bilateral and root osteotomies with unilateral triangular bony wedge resection to allow symmetry of bothnasal bones. Methods. Twenty consecutive patients who presented with bony vault deviation and underwent one-unit osteotomy wereenrolled in this retrospective single-center study. The Nasal Obstruction Symptom Evaluation (NOSE) questionnairewas used to evaluate each patient’s functional outcome. The angle of bony vault deviation before and after one-unitosteotomy was measured using a protractor and compared with the results of 14 patients who had undergone con-ventional osteotomy. The improvement in dorsal deviation was evaluated using facial photography preoperatively and3 months postoperatively. Results. NOSE values improved from 8.4±6.4 to 4.1±4.2 (P =0.021). The angle of bony vault deviation improved from6.9°±2.2° to 2.1°±1.2° (P <0.001) in one-unit osteotomy and from 7.3°±4.0° to 2.7°±1.2° (P =0.001) in conven-tional osteotomy. The preoperative deviation angle improved by 70.3% in one-unit osteotomy compared with 56.6%in conventional osteotomy, which was a significant difference (P =0.033). The mean grade of the postoperative esthet-ic outcomes for the remaining deviation was 1.6±0.5, which was similar to that in the conventional osteotomy group. Conclusion. One-unit osteotomy is a relatively simple procedure that balances the width of both lateral walls by removingexcessive bony fragments from the wider bony wall and providing better structural integrity. This technique improvesfunctional outcomes and has equivalent esthetic results to those of the traditional procedure.
