Electrical burns to the oral commissure: does splinting obviate the need for commissuroplasty?

Two groups of children who had sustained electrical burns to the oral commissure were compared. The first group (n = 20) underwent splinting of the commissure and the other group (n = 22) did not have splints as part of their treatment regimen. The mean age at the time of burn was 3 years in both groups. The need for commissuroplasty was significantly decreased in the splinted group (P = 0.0007 by Fisher's exact test). Further analysis of the duration of splinting in the splinted group (n = 20) revealed that all seven children who required commissuroplasty underwent splinting for less than 4 months while all 13 children who did not require surgery used their splints for more than 4 months (range 4-8 months).
