The role of exclusive enteral nutrition in the management of orofacial granulomatosis in children.

BACKGROUND: Orofacial granulomatosis (OFG) is a term used to describe a persistent, painless swelling of lips and orofacial region. It can be associated with ulceration, gingival hypertrophy and cobble stone appearance of the buccal mucosa. OFG is commonly associated with Crohn's disease and can precede the intestinal manifestation of the disease. Exclusive enteral nutrition (EEN) is a recognized treatment for induction of remission for Crohn's disease. The aim of this study was to review the use of EEN in the management of OFG in children. METHODS: Retrospective review of medical records of all children diagnosed with OFG between 2007 and 2012 was conducted. Presence of comorbidities, progression to inflammatory bowel disease (IBD) and response to EEN was evaluated. RESULTS: Twenty-nine children were included, mean age at diagnosis was 9 years (standard deviation 3.9) years. Ten children had isolated OFG and 19 had OFG and IBD, of which 12 presented with OFG and IBD and 7 developed IBD later. Median time to progression to IBD was 33 months (inter quartile range: 9.8-85.5). Twenty-two children completed 6 weeks of EEN, and 19 showed clinical improvement in the OFG appearance. CONCLUSION: EEN appears to be an effective treatment option for children with isolated OFG or OFG and IBD.
