LARY_20479_sm_suppinfo.mov2111KThe instrumentation for transillumination sinuplasty differs from standard balloon sinuplasty sets in two ways. The balloon contains markings to enable correct placement of the balloon into the sinus ostium. The guidewire contains a small light at the distal tip. When the frontal sinus is cannulated with the Luma lighted guidewire, transillumination is visible on the face in the region of the sinus. Correct placement is indicated by a focus of light that moves freely throughout all areas of the sinus. After confirmation of placement, the balloon is advanced until the yellow band is visible endoscopically outside of the distal end of the guide catheter. This corresponds to the white marking on the balloon completely entering the proximal end of the guide catheter. This yellow band indicates that the distal and of the balloon has exited the guide catheter. The balloon is then inflated, deflated, and removed, revealing a dilated sinus. In many cases additional removal of diseased tissue can be done with classical microdebrider technique. When the maxillary sinus is cannulated with the Luma lighted guidewire, transillumination is visible over the check, with a focus of light moving freely within the sinus. If the tip of the guidewire is positioned posteriorly within the maxillary sinus, transillumination may only be visible on the palate.
