Application of a modified Kleinsasser laryngoscope in two cases / Módosított Kleinsasser-laringoszkóp bemutatása két eset kapcsán

ABSTRACT

In cases of transoral laryngeal and hypopharyngeal surgeries, the exploration of these relatively narrow anatomical regions is paramount. The conventional operational endoscopes allow the visualization of the surgical field, but - due to their structure - are not optimal regarding the coordination and simultaneous moving of microsurgical instruments. Furthermore, the relatively great distance between the surgical microscope and the endoscope has a negative impact on the illumination of the surgical area and the physical characteristics of the laser beam. The authors introduce a modified laryngoscope used in the field of laryngeal and hypopharyngeal surgery. The openings in the sides of the endoscope allow the lateral insertion of microsurgical devices, while the distance between the microscope and the target area can be significantly reduced. The endoscope is presented in addition to a tongue base and a glottic surgery. The introduced operational endoscope allows optimal exploration of the area of interest, the free and simultaneous moving of the microsurgical instruments, and the optimal usage of the laser beam.
