New classification system of contracted nose and its treatment algorithm

Area of Science:

• Plastic Surgery
• Otolaryngology
• Facial Plastic Surgery

Background:

• Nasal contracture is a severe complication post-rhinoplasty, particularly in East Asian patients.
• Existing classification systems and treatment algorithms for nasal contracture are insufficient.
• This study addresses the need for a standardized approach to managing contracted noses.

Purpose of the Study:

• To develop a novel classification system for contracted noses in East Asian patients.
• To establish a treatment algorithm based on the new classification.
• To improve treatment outcomes for revision rhinoplasty in cases of nasal contracture.

Main Methods:

• Retrospective study of 62 patients with nasal contracture undergoing revision rhinoplasty (March 2017 - March 2021).
• Patients were classified into three groups based on a new system.
• Treatment was tailored to the classification, and outcomes were assessed using the Rhinoplasty Outcomes Evaluation (ROE) scale.

Main Results:

• The study included 59 females and 3 males (mean age 29.45 years).
• Classifications included mild (72.58%), moderate (17.74%), and severe (9.68%) nasal contracture.
• Statistically significant differences were found in prior procedures and infection history among groups, but postoperative ROE scores were similar, indicating overall satisfaction.

Conclusions:

• A new classification system and treatment algorithm for contracted noses have been established.
• This system is based on pathological anatomical changes and effectively guides treatment.
• The developed algorithm leads to good treatment results and patient satisfaction.
