    Abstract:
    INTRODUCTION: We report on our experience with surgical management of nosocomial Mycobacterium abscessus cervical lymphadenitis in the setting of an epidemic linked to a dental practice in the community. METHODS: This is an observational case series of children who required surgical treatment of cervical lymphadenitis as part of multidisciplinary management of nosocomial M. abscessus infections. We describe the criteria for surgical management of cervical lymphadenitis as well as patient characteristics and outcomes. RESULTS: Over 1000 children undergoing pulpectomies and pulpotomies at a local dental practice with a contaminated water source were identified as potentially susceptible to atypical mycobacteria infection, identified as M. abscessus. Between August 2016 and May 2017 108 children underwent inpatient evaluation at our institution by general pediatricians and pediatric infectious disease specialists. 90 children required at least 1 surgical intervention by pediatric otolaryngology and/or oral and maxillofacial surgery (OMFS). Children were evaluated by the Pediatric Otolaryngology service if computer tomography (CT) scan of the neck demonstrated lymph nodes of at least 1.5 cm in shortest dimension or lymph nodes with central hypolucencies suspicious for infection with central necrosis. Pediatric Otolaryngology intervened on 11 patients all of whom required selective cervical lymphadenectomy with or without curettage. These patients ranged in age from 3 to 8 years; 8 were male, 6 had concurrent pulmonary nodules. Two patients underwent curettage in addition to lymphadenectomy. Five patients required at least 2 surgical interventions by Pediatric Otolaryngology. CONCLUSION: We found M. abscessus to be an aggressive infection requiring early cervical lymphadenectomy in select patients.
