Summary

Facial pinprick sensitivity varies significantly between the left and right sides of the face, with the upper lip being most sensitive. This highlights the need for careful interpretation during neurosensory examinations.

Area of Science:

  • Neuroscience
  • Sensory Physiology

Background:

  • Assessing facial sensation is crucial for clinical neurosensory examinations.
  • Understanding normal variations in pinprick sensitivity is essential for accurate diagnosis.

Purpose of the Study:

  • To quantitatively evaluate pinprick sensitivity at specific facial sites.
  • To determine if facial pinprick sensitivity differs between the left and right sides.
  • To identify specific facial areas with the highest and lowest pinprick sensitivity.

Main Methods:

  • Twenty-eight healthy adults underwent pinprick testing at ten matched facial sites.
  • A standardized dental explorer with controlled indentation was used.
  • A magnitude matching procedure, adjusted for visual brightness perception, minimized subject variability.

Main Results:

  • Pinprick sensation was significantly sharper on the left side of the face compared to the right (p < 0.0001).
  • Significant differences in sensitivity were observed across different facial test sites (p < 0.0001).
  • The upper lip vermilion showed the highest sensitivity, while the lower lip vermilion showed the least.

Conclusions:

  • Facial pinprick sensitivity exhibits significant lateral asymmetry and site-specific variations.
  • Clinical interpretation of altered facial sensation requires consideration of these normative spatial differences.
  • Accurate neurosensory assessment necessitates awareness of normal sensory topography.
