[Graphic method of recording olfactory disorders]

Area of Science:

• Neuroscience
• Ophthalmology
• Sensory science

Context:

• Olfactory testing is crucial for diagnosing smell disorders.
• Current methods lack standardized graphical representation.
• Differentiating between olfactory and trigeminal nerve responses is challenging.

Purpose:

• To present a novel method for recording threshold olfactometry results using olfactograms.
• To establish a standardized graphical representation for olfactory function evaluation.
• To utilize olfactograms for differential diagnosis of olfactory disorders.

Summary:

• A new method for recording threshold olfactometry results is presented, utilizing olfactograms.
• The use of a deciodor unit provides a standardized zero line for olfactograms.
• Olfactograms visually represent results for olfactory, olfactive-trigeminal, and olfactive-glossopharyngeal responses.
• The study demonstrates olfactograms from patients with diverse olfactory impairments.

Impact:

• Olfactograms offer a valuable tool for the differential diagnosis of olfactory dysfunction.
• This graphical method enhances the interpretation of olfactory test results.
• The deciodor unit standardizes comparative evaluation of olfactory function.
