摘要

The invention relates to medicine, in particular to oncological surgery, otorhinolaryngology and dentistry, and can be used for treating cancer of the paranasal sinuses (maxillary, ethmoidal, sphenoidal, frontal) and skull base.Summary of the invention consists in that the clinical and paraclinical examination is carried out with the determination of the correct localization of the tumor in the paranasal sinus (maxillary, ethmoidal, frontal, sphenoidal) and skull base region. The patient is placed on his back, rotating by 15° in the opposite direction of tumor localization, it is performed the general anesthesia, is treated the operative field and is made an incision of the skin in the region of the face, starting from the region of the forehead, above the frontal sinus, near the inner corner of the eye, then on the cheek on the nasolabial line below the wing of the nose up to 1 cm and to the maxillary sinus, the incision line is parallel to the Ongren line, dividing the maxillary sinus into two segments, namely the posterosuperior and anteroinferior segment, after which is ligated the external carotid artery. With the electric scalpel is performed the incision of the subcutaneous layer, soft tissues to the bone layer. The formed skin flaps of the cheek are separated to the outside, then, using the dental round cutter are made holes in the bone layer, which merge forming a linear bone defect, are removed the separated bone fragments to gain access to the ethmoidal, maxillary, sphenoidal sinuses and the skull base, through which is removed the tumor. It is performed the final hemostasis and plasty of the obtained defect with musculocutaneous vascular pedicle flap prepared from the muscle adjacent to the defect, then the soft tissues are sutured in layers.
