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.

One of the treatment options is a quick, reversible simple suture vocal cord lateralizing technique, whereby the arytenoid cartilage is directly lateralized to the normal abducted position. Considering pediatric laryngeal anatomy, a small endolaryngeal thread guide instrument was designed for precise suture insertion.

The popular endoscopic procedures have only a limited role in the treatment. Considering our clinical experiences, endoscopic arytenoid abduction lateropexy (EAAL) after proper mobilization of the fixed joints provides an effective option even in high-grade stenoses.
View Article and Find Full Text PDFObjectives/hypothesis: The varied etiology of bilateral vocal cord immobility (BVCI) requires a wide range of surgical approaches. A new endolaryngeal thread guide instrument (ETGI) is presented here for a minimally invasive endoscopic lateropexy of the arytenoid cartilage, which might serve as a basis for a simple solution for the main types of BVCI.
Study Design: Prospective study of BVCI patients who underwent surgery, including 22 bilateral vocal cord paralyses (BVCP), 12 mechanical fixations (MF), 10 posterior glottic stenoses, and two rheumatoid ankyloses.
