Type I neurofibromatosis (NF) is the most common autosomal dominant disease. It concerns one in 3000 births, the penetrance is close to 100% and 50% of new cases are de novo mutations (17q11.2 chromosome 17 location). Cranio-maxillofacial region is concerned in 10% of the cases, in different forms: molluscum neurofibroma, plexiform neurofibroma, cranio-orbital neurofibroma, parotido-jugal neurofibroma, cervical neurofibroma. These lesions have different prognosis depending on the craniofacial localization: ocular functional risk, upper airway compressive risk, nerve compression risk, aesthetic and social impact. The maxillofacial surgeon in charge of patients with type I NF should follow the patient from the diagnosis and organize the different surgical times in order to take care about the different issues: vital, functional and aesthetic. We describe the treatment of facial localizations of type 1 NF as it is done at the University Hospital of Lyon and at the Rhône-Alpes-Auvergne neurofibromatosis reference center.
