[Endoscopic removal of a mandibular ameloblastic fibro-odontoma]. / Chirurgie endoscopique d'un fibro-odontome améloblastique mandibulaire.

INTRODUCTION: Ameloblastic fibro-odontoma is a rare mixed odontogenic tumor. It occurs predominantly in children and young adults. This article reports a case of ameloblastic fibro-odontoma affecting a young boy who was treated by endoscopy. CASE REPORT: An 11-month-old child was admitted for a right mandibular rapidly growing mass. Computed tomography confirmed the presence of a large radiopaque mass on the right mandible containing compartmented tooth-germs. A biopsy exeresis was performed to completely remove the tumor with an endonasal endoscope. The histological diagnosis was an ameloblastic fibro-odontoma. DISCUSSION: We performed the enucleation with a nasal endoscope to make sure that the entire lesion had been removed. Bone resection was minimal which should decrease the risk of growth disorders. The ameloblastic fibro-odontoma is a rare mixed odontogenic tumor usually asymptomatic and slow growing. Histopathology proves the diagnosis. The treatment is curettage, preserving the adjacent teeth.

[Anhidrotic ectomermal dysplasia (AED): four cases]. / La dysplasie ectodermique anhydrotique: présentation de quatre observations.

INTRODUCTION: Anhidrotic ectodermal dysplasia (AED) or Christ-Siemens-Touraine syndrome is a rare, hereditary genodermatosis, classically X-linked recessive disorder. MATERIAL AND METHODS: [corrected] We report the cases of 3 children and a male adult. RESULTS: The mode of diagnosis, the clinical signs and the therapeutic option are detailed. DISCUSSION: AED is characterized by a malformative state derived from the ectodermal layer of the embryo which results in the triad: anhidrosis (or hypohidrosis), hypotrichosis, anodontia (or hypodontia). Hypohidrosis causes thermoregulation disorders, which in the infant, can be life threatening. It is important to recognize the affection early to avoid accidents of hyperthermia. Once the diagnosis is established, family investigations are necessary to determine whether it is a family form or a new sporadic case. Carrier mothers must be informed of the high risk recurrence for future male infants. Symptomatic maxillo-facial treatment strives to improve masticatory function and facial growth and thus limit the psychological impact and improve patient comfort.

[Extra-oral implants and irradiation: current trends]. / Implants extra-oraux et irradiation: tendances actuelles.

Recommended treatment for head and neck cancer associates surgery and radiotherapy. Indication for bone-anchored epitheses in irradiated patients is also a common situation. The outcome of the implant appears to be improved with a special protocol for hyperbaric oxygen therapy, antibiotic therapy and calcitherapy. The problem of radiotherapy in patients with titanium osseointegrated implants is also discussed.
