| Popis: | Objectives Following the initial use of endoscopes in otology, the pros and cons of these instruments have been questioned increasingly. These instruments cause an increase in temperature that needs to be investigated. In this study, the authors aimed to investigate the temperature increase caused by endoscopes and light sources in the perilymph by performing a stapedotomy in an animal model under anesthesia. Study design The study was performed in a guinea pig model. Methods In the animal model, a simulated otologic stapes surgery was performed at room temperature. The body temperatures of the guinea pigs were monitored; the temperature increase caused by the 0-degree rigid endoscopes with diameters of 3 and 4 mm as well as the light sources, including halogen, light-emitting diode (LED), and xenon lamps, were monitored following the stapedotomy to measure and document the continuous temperature increase in the perilymph using sensors placed at the oval window. Results Rigid endoscopes cause a temperature increase in the tympanum regardless of their diameter when used with xenon and halogen light sources. The LED light caused a relatively small temperature increase. Conclusions The endoscopic instruments used in the stapes operation caused a temperature increase in the oval window. The authors concluded that this heat could easily be transmitted to the cochlea by the perilymph, which has obstructed contact with the outer environment following stapedomy, resulting in neurosensorial damage. |
