A Grading System-Guided Approach to the Severely Contracted Nose

Area of Science:

• Plastic Surgery
• Otolaryngology
• Reconstructive Surgery

Background:

• Capsular contracture is a serious complication of silicone implant-based rhinoplasty.
• Severe contracture can lead to significant nasal scarring and disfigurement.
• A standardized grading system and treatment approach for severe nasal contracture are lacking.

Purpose of the Study:

• To establish a comprehensive grading system for nasal contracture secondary to silicone implant-based rhinoplasty.
• To develop a graduated treatment algorithm based on the proposed grading system.

Main Methods:

• Retrospective analysis of 87 patients with nasal contracture (2012-2021).
• Development and validation of a 5-grade system (I-Vb) based on preoperative photograph evaluation by two plastic surgeons.
• Assessment of inter- and intraobserver reliability using kappa values.

Main Results:

• The proposed grading system demonstrated substantial interobserver agreement (k=0.701-0.723) and excellent/substantial intraobserver agreement (k=0.699-0.822).
• The system reliably categorizes nasal contracture severity.

Conclusions:

• A reliable grading system for silicone implant-related nasal contracture has been established.
• A graduated treatment algorithm, including flap reconstruction for severe cases (grade Vb), is proposed.
• This approach offers an effective solution for managing severely contracted noses.
