Training the osteoplastic flap technique in dogs.

Unlabelled: Access to frontal sinus using the osteoplastic flap technique is indicated in lesions that do not yield endonasal approach. This technique can be practiced with dogs, although delineation of sinusal perimeter in canines is not as easy as it is in humans.

Aim: This study aims at presenting a method to access and delineate the frontal sinus of canines to reproduce the osteoplastic flap technique in man.
