Laser plume containment during flexible transnasal laryngoscopy.

ABSTRACT:

Objective

To evaluate a negative pressure microenvironment designed to contain laser plume during flexible transnasal laryngoscopy.

Methods

The Negative Pressure Face Shield (NPFS) was previously reported as well tolerated with initial use on 30 patients. Diagnostic transnasal laryngoscopy was performed on an additional 108 consecutive patients who were evaluated by questionnaires and sequential pulse oximetry. Further study addressed operative transnasal potassium-titanyl-phosphate (KTP) laser laryngoscopy with biopsy done on four patients employing the NPFS.

Results

The previously described NPFS version 3 (v.3), a transparent acrylic barrier with two anterior instrumentation ports, was modified by repositioning the side suction port closer to the level of the nose a
