The Dual-Plane Diced Cartilage Concept for Nasal Augmentation in Ethnic Rhinoplasty

Area of Science:

• Plastic Surgery
• Rhinoplasty Techniques
• Cartilage Grafting

Background:

• Ethnic rhinoplasty presents unique challenges for dorsal nasal and radix augmentation.
• Improving aesthetic outcomes and graft integration is crucial in reconstructive nasal surgery.

Purpose of the Study:

• To evaluate the efficacy of the dual-plane diced cartilage graft technique for dorsal nasal and radix augmentation in ethnic rhinoplasty.
• To assess aesthetic results and complication rates associated with this novel grafting method.

Main Methods:

• A study of 54 primary rhinoplasty patients (May 2021-May 2023) using endonasal or open techniques.
• Costal cartilage diced grafts, wrapped in rectus fascia, were placed in sub-superficial musculoaponeurotic system and subperiosteal planes.
• Photographic documentation and blinded surgeon evaluation assessed outcomes and complications over a 12-month follow-up.

Main Results:

• High patient satisfaction with 50 out of 54 cases rated as satisfactory or better at one year.
• Outstanding or very satisfactory results were achieved in 50 cases (92.6%).
• No complications, including graft resorption, infection, or skin issues, were reported.

Conclusions:

• The dual-plane diced cartilage graft technique effectively addresses junctional irregularities and enhances dorsal aesthetic contour.
• This method improves augmentation outcomes and graft viability by maximizing tissue interface area.
• The technique offers a safe and predictable solution for dorsal nasal and radix augmentation in ethnic rhinoplasty.
