Palpation of Major Arteries in the Head and Neck

Clinical Applications of Superficial Temporal Artery Palpation

The superficial temporal artery (STA) is a major branch of the external carotid artery that supplies the scalp. Palpation of this artery is a critical clinical technique used for diagnostic and therapeutic purposes.

Importance of STA Palpation

STA palpation helps in assessing vascular conditions, including temporal arteritis and evaluating blood flow in head trauma cases.

Technique of Palpation

• Position the patient comfortably with a relaxed jaw.
• Locate the STA anterior to the tragus of the ear.
• Use the tips of your index and middle fingers to apply gentle pressure.
• Assess the artery for pulsation, irregularities, or tenderness.

Clinical Applications

Temporal arteritis, also known as giant cell arteritis, is a significant condition evaluated using STA palpation. Symptoms such as localized scalp tenderness and reduced pulsation are key diagnostic markers.

Conclusion

Palpation of the STA is a simple yet vital tool in clinical practice for vascular assessments and identifying arterial pathology.
