Comparative Analysis of Endonasal Lateral Osteotomy and Percutaneous Lateral Osteotomyin Patients with Deviated Nose

Background and Objectives The purpose of this study was to compare the effectiveness of percutaneous and endonasal lateral osteotomy for the correction of deviated nose. Subjects and Method Medical records of 60 patients who underwent rhinoplasty to correct deviated nose were reviewed retrospectively. Patients with unilateral osteotomy, revision rhinoplasty, spreader graft, or who had no preoperative or postoperative photos were excluded from the study. The patients were categorized into two groups, which either had C-shaped deviation or I-shaped deviation. Preoperative and postoperative deviation angles were measured and their differences were analyzed according to the approach methods. Results In the percutaneous approach group, 26 patients had C-shaped deviation and 10 patients had I-shaped deviation, whereas in the endonasal approach group, 17 patients had C-shaped deviation and 7 patients had I-shaped deviation. In the percutaneous approach, the deviation angle was statistically improved in the C-shaped deviation, but in the endonasal approach, it was statistically improved in the C-shaped and I-shaped deviation after surgery. In the C-shaped deviation, the average degrees of improvement of percutaneous and endonasal approach were 5.2°±3.6° and 7.9°±5.3°, respectively, which showed significant difference. However, in the I-shaped deviation, the average degrees of improvement of percutaneous and endonasal approach were 2.9°±1.3° and 2.9°±1.0°, respectively, with no significant difference. Conclusion The improvement of deviation angle following osteotomy may be different according to the approach methods for deviated nose. Endonasal approach was more suitable than percutaneous approach in the correction of I-shaped deviated nose. Key words: Nose deformities, acquired ㆍ Osteotomy ㆍ Surgical procedures, operative
