Lower lateral crural turnover flap in open rhinoplasty

Area of Science:

• Plastic Surgery
• Otolaryngology
• Facial Plastic Surgery

Background:

• Lower lateral crural deformities are frequent challenges in rhinoplasty, impacting alar contour and external nasal valve function.
• The shape and position of lower lateral crura significantly affect aesthetic outcomes and breathing.
• This study evaluates the lower lateral crural turnover flap for correcting these deformities.

Observation:

• A retrospective review of open rhinoplasties using the lateral crural turnover flap was performed.
• The technique was applied in primary, secondary, and tertiary cases to assess its efficacy.
• Case examples illustrate the application and outcomes of the described surgical method.

Findings:

• The lower lateral crural turnover flap effectively addresses deformities, weakness, and collapse of the lower lateral crura.
• It can enhance lower lateral crural strength during nasal tip reshaping.
• Contraindications include insufficient crural width; the technique complements other grafting methods for alar support.

Implications:

• The lower lateral crural turnover flap is a versatile and reproducible technique for rhinoplasty.
• It provides enduring aesthetic and functional results, lasting over one year.
• Utilizing adjacent cartilage offers a viable local tissue source for correcting and supporting the lower lateral crura.
