Determination of the projection of the front sinus in the preoperative period

Objective: to create an easy-to-use method for determining the parameters of the frontal sinus in the preoperative period for more effective and safe surgical treatment of the patient. Material and Methods. An algorithm for obtaining parametric projections of the frontal sinus, based on computed tomography of the head. Results. A parametric model of the frontal sinus with indication of its boundaries, wall thickness and depth was constructed on the basis of high-resolution computer tomograms. Using reference points and data of computer tomograms, a stencil of the frontal sinus was formed with its subsequent fixation on the front surface of the forehead, which can be a guide when choosing the optimal place for trepanation in surgical practice. Conclusion. The proposed method allows in the absence of expensive equipment, minimal costs and the need for personnel training to obtain an accurate parametric projection of the frontal sinus, containing the necessary information about the thickness of its walls and depth.
