[Long-term experience with the use of a device for trepanopuncture of original design].
The paper summarizes the experience with the treatment of more than 2,500 patients by trepanopuncture of frontal sinuses using an original device designed by the author. The instrument allows all intraoperative complications to be avoided, ensures maximally injury-sparing one-step intervention, reduces its duration, and enhances safety due to the use of a short-tube cannula and a cap of large diameter (greater than the tube diameter) limiting the depth of trepanation. The device is fixed on the bony wall of the frontal sinus with side cutting edges of the cannula and bone chip collector to prevent its movements and ensure introduction of the cannula at the desired point of the sinus cavity. Simultaneously, isolation of pathological contents of the frontal sinus from the surrounding soft tissues is achieved. Thread tapping on the walls of the trepanation canal decreases the probability of infection of its surface and bone structures in the frontal region because crumpled bone tissue seals the diploetic layer. Finally, the instrument permits to remove the residual material formed during surgery.
