Abstract

Background and study aims: To assess the usability of high resolution fiberscope which has equivalent image quality to that of the esophageal and gastric video endoscopes

Patients and methods: Image resolution of this endoscope was estimated by the United States Air Force (USAF) resolution test chart. Clinical application was done between January and December 2010 and transnasal observation of the larynx and hypopharynx were performed during this period. These examinations were done for screening and follow-up for patients with hypopharyngeal and laryngeal disorders.

Results: This endoscope could distinguish features on a scale of nearly 20 μm, and abnormal vascular patterns on the mucosal surface characteristic of carcinomas were clearly observed under a conventional light source. In addition, these changes on the mucosal surface became more apparent with use of the i-SCAN®. Nevertheless, the handling of this video endoscope was similar to that of popular ENT video endoscopes, and all patients tolerated its use well.

Conclusion: This new device may dramatically improve pharyngolaryngeal examination in ENT clinics.
