An examination is crucial for many reasons, including:
- Assessing a patient’s affect.
- Signs of self-harm.
- Unusual dress that may indicate personality disorders or other psychological issues.
Understanding basic personality disorders can help manage these patients. It is important to have a working knowledge of the basic personality disorders such as:
- Borderline personality.
- Narcissistic personality.
- Histrionic personality.
Examination of the musculature is also essential to account for individual variations.
When examining a patient, pay close attention to their individual anatomy, considering factors such as
- The inverted triangle sign of youth.
- Phi measurements.
- Volume loss.
Overuse of adjacent muscles or target muscles such as the forehead (frontalis) actively contracting and holding up the brow (making it a poor choice to inject and can result in a brow droop).
