Abstract

ConclusionThe new technique of ILM-guided vocal cord biopsy and APC is safe, cost-effective and non-invasive. It provides excellent airway control, adequate exposure of the vocal cords and effective treatment of laryngeal bleeding.ObjectiveSuspension microlaryngoscopy is a standard diagnostic procedure for vocal cord biopsy. In experienced hands failure of the procedure is extremely rare and may indicate a need for more invasive techniques. The aim of this study was to present a new technique of laryngoscopy/vocal cord biopsy and to review the relevant literature.Material and methodsAfter induction of general anesthesia and preoxygenation an intubation laryngeal mask (ILM) was inserted. A flexible bronchoscope was passed through the ILM and an anterior lesion was identified at the vocal cord. Biopsies were taken with forceps inserted through the instrument's working channel. The procedure was performed using video-endoscopic guidance. Bleeding from the wound surface was adequately treated with argon–plasma coagulation (APC).ResultsIdentification of the vocal cords was readily accomplished using the ILM. Only four literature reports matched our search criteria; all used the standard laryngeal mask or other instruments such as a laser or did not use the procedure for definitive therapy.
