Investigating smell disorders is crucial in research and clinical settings. Objective methods like olfactory evoked potentials (OEPs) and respiration olfactometry aid in diagnosing smell dysfunctions, complementing subjective tests.

Area of Science:

  • Otorhinolaryngology
  • Neuroscience
  • Sensory Science

Background:

  • Growing interest in smell disorders necessitates advanced diagnostic tools.
  • Existing psychophysical tests like Sniffin' Sticks, UPSIT, and CCSIT offer subjective smell assessments.
  • Need for objective measures to complement subjective olfactory evaluations.

Purpose of the Study:

  • To highlight the importance of investigating smell disorders.
  • To introduce objective diagnostic methods for olfactory dysfunctions.
  • To provide an overview of available subjective and objective smell testing approaches.

Main Methods:

  • Review of psychophysical smell identification tests (Sniffin' Sticks, UPSIT, CCSIT).
  • Introduction of objective diagnostic techniques: olfactory evoked potentials (OEPs) and respiration olfactometry.

  • Discussion of the complementary roles of subjective and objective testing.

    • Main Results:

    • A variety of subjective smell test kits are available for psychophysical investigations.
    • Objective methods like OEPs and respiration olfactometry provide quantifiable data on smell function.
    • Both subjective and objective methods are valuable for a comprehensive diagnosis of smell disorders.

    Conclusions:

    • Accurate diagnosis of smell disorders requires a combination of subjective and objective assessments.
    • Olfactory evoked potentials and respiration olfactometry represent key objective diagnostic tools.
    • Further research and clinical application of these methods will improve patient care for smell dysfunctions.
