[The thermal trigeminal impulse test. A method for more precise trigeminal nerve testing]

Area of Science:

• Neuroscience
• Sensory Physiology

Context:

• Assessing facial sensory perception is crucial for diagnosing neurological conditions.
• Existing methods for tactile sensitivity assessment may lack the precision needed for subtle thermal perception.
• The trigeminal nerve plays a vital role in facial sensation, including thermal cảm giác.

Purpose:

• To introduce a new, highly sensitive method for quantifying subjective warmth sensitivity thresholds in facial trigeminal nerve innervation areas.
• To compare the sensitivity of this new method against established tactile sensitivity tests.
• To investigate potential correlations between warmth sensitivity, age, and sex.

Summary:

• A novel technique has been developed to measure subjective warmth-impulse sensitivity in facial trigeminal nerve areas.
• This new method demonstrates superior sensitivity compared to traditional tactile sensitivity assessments.
• Results indicate no significant correlation between warmth sensitivity and demographic factors like age or sex.
• The study identified the innervation area of the second trigeminal branch as having the lowest warmth sensitivity levels.

Impact:

• Provides a more refined tool for clinical assessment of facial sensory function.
• May aid in the early detection of subtle neurological changes affecting thermal perception.
• Establishes baseline data for warmth sensitivity in the trigeminal nerve distribution, useful for future research and diagnostics.
