title: Multidisciplinary surgical management of cherubism complicated by neurofibromatosis type 1.
abstract: Cherubism is a rare, autosomal dominant, mostly self-limiting disease of the jaw. It is characterized by bilateral fibrous tissue hyperplasia, giant cell proliferation, and bony degeneration in the lower facial skeleton, which can result in a massive and severely deforming prominence of the maxillomandibular structure. This case study examines the multidisciplinary management of a severe case of cherubism complicated by neurofibromatosis type 1, 2 codominant nonsegregating conditions that were clinically and genetically diagnosed, an extremely rare combination. Adequate mandibular reduction, reconstruction, and dental implantation afforded good restoration of oral function as well as a marked aesthetic improvement.
  
  
  METHODS
  A 14-year-old Fijian girl was referred to our unit for management of severe overgrowth of her mandible that compromised her speech and deglutition. In addition, she displayed clinical features consistent with neurofibromatosis type 1. Radiologic, histologic, and genetic analyses confirmed the diagnosis of both conditions. Our craniofacial multidisciplinary team undertook mandibular reconstruction followed by placement of osseointegrated dental implants.
  
  
  RESULTS
  Mandibular reduction, reconstruction, and dental implantation resulted in a significantly improved functional and aesthetic outcome with no further regrowth at 3-year follow-up when she returned to the United Kingdom for osseointegrated dental implant insertion.
  
  
  CONCLUSIONS
  The successful outcome of this surgically challenging, grossly disfiguring, and rare condition was largely a result of the combined input from our multidisciplinary team, adequate preoperative planning, and the use of a novel surgical technique in debulking and reconstructing her mandible.
