[Nasolabial flap reconstruction of the columella].

We report three cases of squamous cell carcinoma of the columella invading the sub-partitions. Wide resection raised the problem of several nasal esthetics sub-units. A chronological review of columella reconstruction procedures explained why the nasolabial fragment rarely used for partial rhinopoiesis, was appropriate in these three patients.

[Contribution of the semi-free radial forearm flap for head and neck reconstruction].

Flap failure is mostly caused by venous thrombosis of the anastomosis. The failure rate is higher in post-irradiated neck. To reduce the risk of venous thrombosis, the authors propose to harvest the radial forearm flap using the cephalic vein as the drainage vein and as a pedicle.

[Extra-oral implants and irradiation: current trends].

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.
