Strategies to prevent suppurative chondritis following auricular burns: a systematic review.

Objective: Suppurative chondritis is a potentially devastating complication of burns to the ear. The infection and inflammation can liquify cartilage, leading to significant aesthetic deformities which are difficult to treat. This article reviews published measures for preventing post-burn chondritis.

Method: A comprehensive search of all available literature up to September 2020 was performed, according to PRISMA guidelines, for studies assessing preventive measures for post-burn chondritis. Randomised controlled trials (RCT), cohort studies, case-control studies, case reports and series were eligible for inclusion.

Results: A total of 10 studies, including one RCT and nine retrospective observational analyses, were included, incorporating 1369 patients with burns to the ear. The most common interventions were pressure avoidance (70%), daily cleansing (60%), topical mafenide acetate (60%) and targeted debridement (30%). Packages of measures which included pressure avoidance were the most effective, all of which achieved a chondritis incidence of <6%.

Conclusion: Low-level but strong published evidence suggests that important treatment principles include prevention by pressure relief, targeted debridement, prophylactic local antibiotics, local antisepsis and the avoidance of desiccation.
