Puncture in the canine fossa: technique and pros and cons.

The authors describe in detail the technique they are employing for puncturing the canine fossa, for irrigation, sinuscopy and/or register of the antral pressures. Two trocars are introduced, one developed and the other modified by one of the authors (N.P.) A morbid entity named "glue-sinus" is commented. The pros and cons of the technique are discussed concluding that puncture in the canine fossa is a valid procedure and even more advantageous than the one in the nasal inferior meatus.
