Marginal versus segmental mandibulectomy for pediatric desmoid fibromatosis of the mandible – Two case reports and review of the literature

Desmoid fibromatosis (DF) is a rare, benign soft tissue neoplasm with high rate of local recurrence. Surgical management of DF in the head and neck can be challenging given the desire to balance the preservation of form and function with the need to minimize local recurrence by achieving complete resection. We present two contrasting cases which highlight the advantages of marginal mandibulectomy over segmental mandibulectomy in children with DF. We favor marginal mandibulectomy even with limited bone stock given the remarkable ability of children to generate new bone.
