[Surgical problems arising from ethmoid adenocarcinomas]. / Problèmes chirurgicaux posés par les adénocarcinomes de l'ethmoïde.

Adenocarcinomas are the most frequent ethmoid tumors. The only curative treatment at present is surgery. Potential extensions of these tumors require a wide exeresis. This is best ensured with an approach that is cranial and of the Cairns type at first, then in some cases facial and patterned on the Moure-Sebileau course of approach. This procedure demands the immediate reconstruction of the 3 levels involved: the dura mater, the bone and the mucosa of the nasal fossae. We reconstruct the dura mater with a pericranial flap, the bone with bone grafts, and the mucosa with a flap from the galea.
