Kinelaryngoscopy for documentation of laryngeal pathophysiology.
Viewing the larynx has been revolutionized by the advent of the flexible fiberoptic nasopharyngolaryngoscope. For the first time a subject may inspire, expire, cough, swallow, phonate sounds, words, sentences, passages, and sing in full voice as examination and photodocumentation procede. Combining the flexible fiberoptic nasopharyngolaryngoscope with a home video camera, a standard fiberoptic light source, a standard videotape recorder, and a standard color TV set, the author details a method for the production of color and sound videotapes of the larynx in action. The video images are of excellent quality, and may be made in straightforward and economical manner. In fact, the entire array of instrumentation, including the flexible fiberoptic nasopharyngolaryngoscope, light source, video camera, lens, adapter, camera mount, videotape recorder, and TV set may be purchased for significantly less than the cost of the camera that most physicians use for endoscopic photography. The concept of flexible fiberoptic examination of the larynx and videophotodocumentation of the larynx in respiratory, sphincteric, and phonatory action shall be referred to as "kinelaryngoscopy."
