Vertical Alar Folding (VAF): A Useful Technique for Correction of Long and Concave Lateral Crura in Rhinoplasty.

[BACKGROUND] The tripod theory explains the dynamics of the nasal tip, where surgery is difficult because of anatomic variations and pathologies and the various surgical possibilities. Abnormalities or weaknesses of the lateral crura can result in concavity in ala or alar collapse and cause aesthetic and functional impairments of the nose. Several tip plasty techniques and lateral crura modifications are used in rhinoplasty.

[OBJECTIVE] To describe the vertical alar folding (VAF) technique for making modifications in the lateral crura (LC) and rotation of the tip.

[METHODS] Included in the study were 83 patients (59 women, 24 men) undergoing rhinoplasty using VAF with the senior author as surgeon between 2013 and 2018. The mean age was 26.3 years (range 18-47). Mean postoperative follow-up period was 26.7 months (range 12-64). Patients who completed the 1-year postoperative period completed the rhinoplasty outcome evaluation (ROE) questionnaire. Outcome measures were performed at examinations, and preoperative and postoperative photographs of the patients were analyzed.

[RESULTS] In the span of 5 years, no revision surgery was required for technique-specific reasons. In patients who had a droopy or asymmetric tip or long and concave lateral crura, we saw remarkable functional and aesthetic improvements with VAF. According to the ROE questionnaire, 90.3% (75 out of 83) of the patients were content with the aesthetic and functional results.

[CONCLUSION] VAF is a useful and effective method for modifying the LC and tip of the nose. VAF allowed for controlling the rotation and projection of the tip, changing the length of the lateral crus and nose with durability and smooth, symmetric contours, and correcting concavity of a lateral crus for better functioning and aesthetics.
