BACKGROUND:: We present a retrospective, comparative, and analytical cohort study, which aimed to prove the utility of unilateral or asymmetrical bony wedge resection to straighten the twisted nose as applied in the “Let-Down” / “Push- Down” methods. The study involved objective angle measurements preoperatively and postoperatively on frontal view photographs. PATIENTS AND METHODS:: Preoperative and postoperative angle measurements were made on frontal view photographs of 78 patients with twisted noses classified as Type- C and Type –I. Angles of deviation were obtained using Scion Image software, measured in degrees. Statistical analysis was performed using Excel v15.13.3. RESULTS:: 42 patients had twisted nose Type- C and 28 patients had twisted nose Type –I. The mean age was 19 years old. There was 81% improvement ratio for twisted nose Type-C and 79% for twisted nose Type-I, and the angle correction for each type of nasal deformity was statistically significant (p< 0.01). The majority of postoperative results were classified as “excellent to good” except for four cases with “bad” outcomes, including 2 patients with Type-C and 2 with Type-I deviations. CONCLUSION:: Unilateral or asymmetrical bony wedge resection is a modification of the “Let-Down” rhinoplasty technique. This study demonstrates statistically significant improvements in straightening twisted noses among patients with or without preoperative hump, while preserving the nasal dorsum. We found this modification better suited for Type- C deviations.
