An Analysis of Lateral Crural Repositioning and Its Effect on Alar Rim Position.

Area of Science:

• Plastic Surgery
• Rhinoplasty Techniques
• Facial Anatomy

Background:

• Cephalically malpositioned lateral crura frequently cause alar rim retraction in rhinoplasty.
• Alar rim retraction can negatively impact aesthetic outcomes and nasal function.

Purpose of the Study:

• To evaluate the efficacy of lateral crural repositioning for lowering the alar rim.
• To determine if adjunctive grafts improve outcomes when combined with lateral crural repositioning.

Main Methods:

• Retrospective review of 54 patients (102 hemi-noses) undergoing open rhinoplasty with lateral crural repositioning.
• Preoperative and postoperative standardized photographs were analyzed using Adobe Photoshop CS and a modified Gunter technique.
• Statistical analysis using a paired t test compared changes in anterior nostril apex angles.

Main Results:

• Lateral crural repositioning significantly decreased the anterior nostril apex angle by 6.8° (P < .001).
• This reduction was consistent whether the procedure was performed alone or with adjunctive grafts (6.6° decrease, P < .001).
• No significant difference in rim-lowering effect was observed between isolated lateral crural repositioning and its combination with grafts.

Conclusions:

• Lateral crural repositioning is a statistically significant method for lowering the alar rim.
• The addition of grafts to lateral crural repositioning does not provide a substantially greater rim-lowering effect.
• This technique offers a reliable solution for managing alar rim retraction in rhinoplasty.
