Complications Associated with Alloplastic Materials in Rhinoplasty and Their Operative Management.

Area of Science:

• Plastic Surgery
• Otolaryngology
• Biomaterials Science

Background:

• Dorsal augmentation rhinoplasty presents unique challenges in Asian populations.
• Alloplastic materials are commonly used but associated with significant complication risks.
• Grafting material choice for dorsal augmentation remains a subject of ongoing debate.

Purpose of the Study:

• To report experiences with alloplastic material extrusion and infection after dorsal augmentation rhinoplasty.
• To evaluate the efficacy of one-stage revision rhinoplasty using autologous rib cartilage.
• To assess novel postoperative screening tools for outcome evaluation.

Main Methods:

• Retrospective review of 18 patients with prior alloplastic dorsal augmentation.
• One-stage revision surgery involving explantation of alloplastic material and reconstruction with autologous rib cartilage.
• Postoperative assessment using clinical examination, ultrasound, 2D/3D imaging, and MRI.

Main Results:

• All patients experienced complications such as foreign body infection and/or partial extrusion.
• Successful outcomes achieved using autologous rib cartilage (solid grafts, diced cartilage in fascia, or diced cartilage in platelet-rich fibrin).
• Novel screening tools demonstrated effectiveness in outcome assessment.

Conclusions:

• Alloplastic dorsal augmentation carries risks of foreign body reactions, infections, scarring, and poor long-term results.
• Single-stage revision with autologous cartilage yields aesthetically and functionally satisfying outcomes.
• Advanced imaging techniques aid in postoperative evaluation of revision rhinoplasty.
