A Novel Single-Incision Approach for Thyroid Cartilage Augmentation Using Thyroid Alar Grafts

Area of Science:

• Surgical Innovation
• Gender-Affirming Surgery
• Plastic and Reconstructive Surgery

Background:

• Thyroid cartilage masculinization is a key aspect of gender-affirming surgery.
• Traditional methods using rib cartilage cause donor site morbidity.
• A less invasive alternative is needed for thyroid cartilage augmentation.

Purpose of the Study:

• To describe a novel single-incision technique for thyroid cartilage augmentation.
• To evaluate the efficacy and patient satisfaction of using autologous thyroid alar cartilage grafts.
• To present an alternative to traditional augmentation methods with reduced donor site morbidity.

Main Methods:

• A novel single-incision technique was developed for thyroid cartilage augmentation.
• Autologous thyroid alar cartilage grafts were harvested and fashioned into a neothryoid notch construct.
• The graft was secured to the native thyroid cartilage to enhance anterior projection in a transmale patient.

Main Results:

• The procedure was performed successfully via a single high cervical incision.
• The patient experienced no complications and reported high satisfaction with aesthetic and tactile outcomes.
• Postoperative assessment at 15 days and 9.5 months confirmed positive results.

Conclusions:

• Thyroid alar cartilage grafting is a promising, less invasive option for thyroid cartilage masculinization.
• This technique avoids the morbidity associated with distant donor sites like rib cartilage.
• The single-incision approach offers effective augmentation with improved patient outcomes.
