Lateral Crural Turn-Up Flap for Increasing the Volume of Cartilaginous Nasal Sidewall in Closed-Approach Dorsal Preservation Rhinoplasty.

[BACKGROUND] Dorsal preservation rhinoplasty can also be applied in crooked nose cases. This article describes a lower lateral cartilage-based flap (lateral crural turn-up flap) used to correct cartilaginous nasal sidewall asymmetries. It was aimed to introduce a flap to be used in crooked nose cases operated with dorsal preservation rhinoplasty and to show possible modifications of this flap.

[METHODS] Eight patients who had lateral crural turn-up flap due to crooked nose between July and December 2021 were included in this retrospective study. Standardized preoperative and postoperative 12-month front-view photographs were analyzed and scored for correction of midvault nasal sidewall asymmetries by 2 plastic surgeons. The Rhinoplasty Outcome Evaluation (ROE) scale was applied at 12 months.

[RESULTS] The mean score given by the surgeons for correction of midvault nasal sidewall asymmetries was 4.18. The mean ROE score was 89, and all patients were satisfied according to their ROE scores. There were no major complications.

[CONCLUSIONS] Unilateral lateral crural turn-up flap seems to be effective in correcting cartilaginous nasal sidewall asymmetries in crooked nose cases operated with dorsal preservation rhinoplasty.
