The purpose of the work is to estimate the efficiency of intraoperative neuromonitoring used as a means for preventing damage to the recurrent laryngeal nerve in thyroid surgery.The basis for the work is the analysis of surgical treatment in 120 patients with various diseases of a thyroid gland, of whom 60 patients being operated using intraoperative neuromonitoring.The surgical neuromonitor "Neurosun 400"was used for the purpose of monitoring ("INOMED", Germany). The main objectives of intraoperative neuromonitoring were the emergency detection and localization of a nerve, its exact differentiation from the surrounding tissues by means of a stimulator.Intraoperative neuromonitoring of a recurrent laryngeal nerve by means of the Neyrosan-400 device has considerably reduced time of searching the nerve. So, the time of search was averaged 9.2±0.8 min. in the control group, whereas in the main group -3.1±0.7 min. (р <0.05). As a result, the general time of operation has decreased.The general duration of operation in the control group of patients was averaged 63.7±6.1 min., in the main group -45.4±5.8 min. (р <0.05).The obligatory visualization is necessary for reliable prevention of damage to a recurrent laryngeal nerve during operation.The recurrent laryngeal nerve has an accurate minimum threshold of stimulation which is -0.5ma, no matter what the patient's age is.Using neuromonitoring in thyroid surgery with the Neyrosan-400 device allows both conducting emergency and accurate identification of a recurrent laryngeal nerve in all cases as well as avoiding traumatic damage.

Nowadays, postoperative wound complications are quite frequent in surgery. Various medicines and physical methods are widely used to accelerate reparative regeneration (1,2). So far, the effect of oxygen air ions on the wound healing process has not been studied. Meanwhile, aeroionotherapy, characterized by an anti-oxidant action, can have an inducer effect.The purpose of the research was to study the effect of oxygen air ions on the regeneration of tissue structures of a laparotomic wound.Clinical and laboratory studies were conducted in 48 patients (divided into two groups) with acute peritonitis of appendicular origin. The patients of the basic group underwent aerorionotherapy in the early postoperative period.While using aeroionotherapy, the reparative process was faster and more perfect. The effect of oxygen air ions was accompanied by an acceleration of the inflammatory reaction course, which is manifested by the rapid migration of cellular elements to the wound surface and their differentiation into the connective tissues. This important fact explains the anti-inflammatory effect of such therapy, its capability to inhibit the alterative process and stimulate the reparative process. In the basic group, the intensity of biological consolidation was significantly different from that of the comparison group. Only 3 days after the operation, it was higher than the control value by 23.2%, after 5 days -by 37.7%, after 7 days -by 35.6% (p <0.01).Thus, the obtained data suggest that the negative oxygen air ions should have a rather pronounced regenerative effect.

Two methods for the plastic reconstruction of degenerative Achilles tendon ruptures have been developed, using biological xenopericardium prosthetics. 21 patients were operated. In cases of tendon gliding surface deformation, the insulating plastic reconstruction was used in 14 of them by wrapping the suture area with xenopericardium; the replacement plastic reconstruction was applied in 7 patients. In case of an unrecoverable defect, the tendons were replaced with a specially formed
