Use of a polyvinyl acetyl sponge (Merocel®) nasal pack to prevent kinking of the endotracheal tube used during laser excision

      Intraoral laser excision requires use of an endotracheal tube that can safely be used with a laser. A recognised complication when using these tubes is that they kink at the proximal end where the tube leaves the nose at an acute angle, which can cause it to narrow with resultant delays (Fig. 1). This can be particularly inconvenient when the face has been suitably draped.
