Area of Science:

  • Otorhinolaryngology
  • Neuroscience
  • Sensory Science

Context:

  • Olfactory and trigeminal sensitivity are foundational to the sense of smell.
  • Current odor analysis faces challenges in precise measurement.
  • Clinical assessment of smell requires robust methodologies.

Purpose:

  • To redefine olfactometry for contemporary odor analysis.
  • To critically evaluate subjective and objective olfactometry methods.
  • To comprehensively review olfactory disorders and their clinical implications.

Summary:

  • Olfactometry methods are discussed, differentiating subjective approaches from objective electrophysiological recordings like electric response olfactometry.
  • Objective methods, such as electric response olfactometry, offer more reliable measures of olfactory function.
  • A complete olfactory assessment integrates rhinomanometry for nasal airflow capacity.
  • Olfactory disorders are categorized into airborne and sensorineural types, with detailed etiological factors including environmental, neurological, and systemic diseases.

Impact:

  • Highlights the efficiency of electric response olfactometry in assessing olfactory function.
  • Provides a framework for understanding and diagnosing diverse olfactory disorders.
  • Underscores the importance of objective olfactometry in expert evaluations of smell dysfunction.
