摘要：Introduction. The presented study is an attempt to comprehensively analyze the lateral spread of heat during thyroidectomy.Obtained results may be valuable in other surgical disciplines in which thermal analysis is difficult or impossible.Objective. The aim of the study was to evaluate the temperature distribution in the operating field during thyroidectomyperformed with the use of modern haemostatic instruments, and to define the safety margin for the investigated devices.Materials and methods. Ninety-three patients were thyroidectomised due to thyroid neoplasm. During all the operationsthe thermovisual measurements were carried out along with continuous intraoperative neuromonitoring of the recurrentlaryngeal nerve (CIONM). Investigated patients were divided into 5 groups, named according to the applied haemostatictechnique: LigaSure (N=17); ThermoStapler (N=20); Focus (N=19); SonoSurg (N=17) and Monopolar (N=20).Results. At maximal performance settings, the highest working temperature was observed for the ThermoStapler, whilethe lowest temperature was recorded for the Monopolar. Safety margin and working time were increased in Focus andSonoSurg, compared to LigaSure and ThermoStapler. The differences in the necrosis thickness were negligible. The largestdistance of the midline of the active blade from isotherm of 42ºC observed in the study was 5.51 mm; none of investigateddevices used at a bigger distance had influence on the morphology of the electric signal of CIONM.Conclusion. The thermo-visual camera allows non-invasive, safe, and real-time monitoring and analysis of temperaturedistribution in the operation area during thyroidectomy. Proposed minimal safety margin for the analysed devices is 5.51 mm
