| Popis: | The aim of study is to develop a new method of connecting the dura mater (DM) defects in frontal sinus tumors with intracranial spread using high-frequency bipolar coagulation for welding of living tissues. Depending on the method of DM defect repair, patients were divided into two groups. The 1st group (control) included patients whose DM defect was connected according to the conventional method (suturing with polypropylene threads), in the 2nd group—the DM defect was connected by high-frequency bipolar electric welding using EKVZ-300, Patonmed. As a result of the study, the authors proposed an effective method of connecting the DM defects after the removal of frontal sinus tumors spreading intracranially. Such methods include a high-frequency bipolar electric welding method, the use of which contributed to a minimal destructive effect on adjacent tissues, but at the same time hermetically connected the DM. This was possible due to the supply of current with certain wave characteristics in a certain modulation at a temperature of 40–48°C, resulting in the connection of tissues without the formation of a coagulation scab due to the mechanism of protein-associated electrothermal adhesion of tissues. Presented data indicate significant advantages of using high-frequency bipolar electric welding the DM defects and fascia lata to restore the closed physiological circuit of cerebrospinal fluid circulation, compared to the traditional suture method. This approach has reduced intra- and post-operative complications, the time of surgery, and the length of the postoperative period. |
