Development and Validation of a NIRS-based Sinusitis Screening


The research at University of California Irvine, Beckman laser institute and Praxis Biosciences Incorporation, develope near-infrared trans-illumination methods. The optical imaging tool that can determine acute sinusitis and the response to treatment therapy.

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: July 2020

Detailed Description

In the United States, approximately one in seven people develop sinusitis each year, and 20 million cases of acute bacterial sinusitis become chronic to require medical treatment. The optic light from the illumination wand travelled through the pallet into the sinuses and exited the face. The optic device can determine air-filled and fluid/tissue-filled spaces in the sinus cavity during clinical exam.
