Abstract
Introduction Low exposure of the larynx can make laryngeal microsurgery difficult or even impossible.
The application of rigid and contact endoscopy enabled oblique and retrograde angled
visualization, allowing transoperative staging with greater reach of the anatomical
areas. However, there is difficulty or even impossibility of performing the surgical
act, due to the incompatibility of the angled path with the straight surgical tools.
Objective To demonstrate the efficiency of the variant of the technique for laryngeal microsurgery
in cases of difficult laryngoscopy and to analyze the new surgical instruments specific
to the endoscopic procedure.
Methods This is a cross-sectional retrospective study, based on the analysis of 30 medical
records of patients treated surgically at a philanthropic hospital in the state of
Sergipe, Brazil, between the years of 2014 and 2015.
Results The technical variant used 30- and 70-degree endoscopes that provided complete oblique
view of the endolarynx. The association of angled instruments (forceps, suction pumps,
retractors and scissors) enabled the execution of the surgical procedures.
Conclusion The association of rigid endoscopy with angled instruments promoted full visualization
of the surgical lesion and operative resolution.
