Alar setback technique: a controlled method of nasal tip deprojection.

Area of Science:

• Plastic Surgery
• Facial Aesthetic Surgery
• Rhinoplasty Techniques

Background:

• Overdeveloped alar cartilages can lead to excessive nasal tip projection, a common concern in rhinoplasty.
• Existing deprojection techniques may have limitations in correcting this specific deformity.

Purpose of the Study:

• To describe a novel alar cartilage-modifying technique for nasal tip deprojection.
• To compare this technique with other methods for correcting overprojected nasal tips due to alar cartilage hypertrophy.

Main Methods:

• A case series of 20 patients undergoing rhinoplasty for overprojected nasal tips caused by overdeveloped alar cartilages.
• An external rhinoplasty approach was used to perform medial and lateral crural shortening (alar setback).
• Objective (Goode ratio, nasofacial angle) and subjective evaluations were conducted pre- and postoperatively.

Main Results:

• The alar setback technique effectively reduced nasal tip projection, confirmed by significant improvements in the Goode ratio and nasofacial angle.
• A low setback was performed in 80% of cases, and a high setback in 20%.
• No complications or need for revision surgery were reported during the mean 18-month follow-up.

Conclusions:

• The alar setback technique offers precise deprojection, controlled tip rotation, and preserves nasal tip aesthetics and support.
• It enhances nasal tip complex strength and stability while maintaining normal proportions and avoiding alar flaring.
• The technique requires an external approach and meticulous surgical skill.
