Resection of ALHs located on arytenoids under a microlaryngoscope using a CO2 laser
After the larynges and adjacent sites were exposed using the laryngoscope, a WILD Heerbrugg M 655 microscope (WILD Heerbrugg, Jena, Germany) and 400-mm focal lens coupled with a LUMENISTM 40 model CO2 laser (Lumenis Ltd., Yokneam, Israel) were used. Two hundred and seventy micron spots and the super-pulse mode at 5-7 W were used. After the ALHs were elevated using the micro laryngeal forceps, the CO2 laser was used to remove the ALHs along the base of the lesions. One of the ALH patients had a tumor with a limited base and high volume. The CO2 laser was applied after the volume of the ALH was reduced by siphoning off blood from the ALH using a 23-gauge needle.
Resection of ALHs located on arytenoids under a microlaryngoscope usinga holmium laser
A holmium laser (VersaPulse PowerSuite, Lumenis, Yokneam, Israel) with 550 micron end-firing fiber to deliver the laser beam was used. En bloc resection was performed at the base of the ALHs. The laser was set to deliver 3W of energy.
