Pediatric Postburn Ear Reconstruction of Significant Cartilage Defects

Abstract

Abstract The external ear is a vulnerable appendage susceptible to trauma. Repairing and recreating its intricate architecture presents a formidable challenge after burn injury, especially when scar tissue, impaired vasculature, and damage to cartilage all influence reconstructive options. The authors share their institutional experience and provide a guide for reconstruction of significant postburn auricular cartilage defects. A retrospective review was conducted on 54 patients (61 ears) aged 0–21 years old admitted to a specialized pediatric burn hospital between January 2004 and January 2021 for postburn ear cartilage reconstruction. Conchal cartilage grafting was performed in 9 patients (9 ears) with an average age of 14.0 ± 5.1 years, requiring an average of 2.0 ± 1.0 procedures that resulted in one case of infection. A total of 21 patients (24 ears) with an average age of 15.1 ± 4.5 years underwent a conchal transposition flap, requiring an average of 1.8 ± 0.4 procedures that resulted in no major complications. A total of 20 patients (23 ears) with an average age of 12.0 ± 5.3 years underwent porous polyethylene implantation, requiring an average of 3.5 ± 1.5 operations that resulted in 3 complications. Costal cartilage grafting was performed in 4 patients (5 ears) with an average age of 13.2 ± 5.3 years, requiring an average of 3.2 ± 2.2 operations that resulted in one case of infection. Postburn ear cartilage defects necessitate an individualized approach tailored to a patient’s reconstructive goals. In addition to defect size and location, factors such as reconstructive course duration, complication potential, and anticipated aesthetic results should be discussed with the patient.
