Clinical problems in chemosensory disturbances.

Area of Science:

• Otolaryngology
• Neuroscience
• Psychophysics

Background:

• Smell and taste are vital for food enjoyment and safety, yet clinical evaluation is challenging.
• Current diagnostic methods for chemosensory disorders lack standardization.
• Otolaryngologists must address smell and taste dysfunction comparable to hearing and balance issues.

Purpose of the Study:

• To highlight the need for standardized psychophysical measures in evaluating smell and taste disorders.
• To review current research and identify areas for improving diagnosis and treatment.
• To differentiate between transport, sensorineural, receptor, and neural deficits.

Main Methods:

• Review of common causes of smell and taste abnormalities.
• Analysis of current research with clinical relevance.
• Discussion of opportunities for basic science studies.

Main Results:

• Clinical evaluation is hindered by difficulties in stimulus control and response measurement.
• Anatomical diagnosis aids etiological diagnosis, distinguishing various deficit types.
• Common causes and current research are identified.

Conclusions:

• Psychophysical measures are essential for defining disability in smell and taste disorders.
• Further research can improve diagnostic accuracy and therapeutic strategies.
• Available technology can support advancements in this field.
