A new distending laryngoscope for diagnosis and microsurgery of the larynx

A new laryngoscope was developed in order to improve visualization of the larynx and to better adapt the instrument to individual clinical circumstances. As such, the Kleinsasser laryngoscope was divided into two parts, with the width between the two halves changed by adjustment of a screw. The lower part of the instrument can also be moved to provide more space near the larynx. Since the laryngoscope is open laterally, there is more space for the operator, and shorter instruments can be used for endolaryngeal manipulations. The endoscope can be used for intubation as well as for injection. With the new instrument the advantages of the Kleinsasser laryngoscope with the Killian suspension endoscope have been combined.
