Pediatric Plastic Surgery Under Local Anesthesia.

BACKGROUND: Increasing research has shown that select surgical procedures can be performed in an office-based environment with low complication rates. Within the field of plastic surgery, these findings have mainly been studied in adult populations. However, studies regarding the safety and efficacy of office-based plastic surgery in the pediatric population are lacking. In the present study, we demonstrate that appropriately selected office-based pediatric plastic surgery procedures can be performed under local anesthesia for a variety of common surgical indications with low complication rates. METHODS: A retrospective case series of pediatric plastic surgery patients who underwent in-office procedures under local anesthesia at a single academic institution from September 2014 to June 2020 was performed. RESULTS: Five hundred nine patients were treated in an office setting for various etiologies over the study period. A total of 48.9% of the patients were male and 51.1% were female. Patient age at time of procedure ranged from 24 days to 17 years of age with a median age of 13 years. A total of 778 lesions were treated. There were 10 total complications (1.29%) over the study period with only one surgical site infection that resolved with antibiotic treatment. CONCLUSIONS: Our work indicates that select pediatric plastic surgery procedures can be performed under local anesthesia with low complication rates.

Evaluation of peripheral nerve regeneration in Murphy Roths Large mouse strain following transection injury.

Aim: Murphy Roths Large (MRL/MpJ) mice have demonstrated the ability to heal with minimal or no scar formation in several tissue types. In order to identify a novel animal model, this study sought to evaluate whether this attribute applies to peripheral nerve regeneration. Materials & methods: This was a two-phase study. 6-week-old male mice were divided into two interventional groups: nerve repair and nerve graft. The MRL/MpJ was compared with the C57BL/6J strain for evaluation of both functional and histological outcomes. Results: MRL/MpJ strain demonstrated superior axon myelination and less scar formation, however functional outcomes did not show significant difference between strains. Conclusion: Superior histological outcomes did not translate into superior peripheral nerve regeneration in MRL/MpJ strain.
