Which feature of the face should be assessed for symmetry?

The symmetry of the eyelids and nasolabial folds is a critical aspect of a facial assessment because these features are key indicators of facial nerve function and overall facial symmetry. When assessing the eyelids, any difference in drooping or position can suggest neurologic issues, such as Bell’s palsy or a stroke. Similarly, nasolabial folds, which run from the sides of the nose to the corners of the mouth, can reveal discrepancies that might result from muscular weakness or other conditions affecting facial appearance and movement.

Evaluating these areas for symmetry allows healthcare professionals to identify potential abnormalities that may not be immediately apparent in other facial features. For instance, uneven nasolabial folds can signal problems with muscle tone or nerve damage. Therefore, focusing on the eyelids and nasolabial folds provides valuable insight into both aesthetic and functional aspects of facial health.
