Ultrasound Teaching


Most neck masses can be initially assessed by an ENT/head and neck surgeon through history taking and physical examination. For example, if nasopharyngeal carcinoma is suspected, a biopsy is performed directly.
If there is uncertainty, the physician may arrange a neck ultrasound examination. Thus, history taking and physical exam remain the first step, while ultrasound serves as an adjunct tool.

Diagnosis and Follow-up of Nasopharyngeal Carcinoma Using Ultrasound: Journal Report

This case shows that history and physical exam are still primary for diagnosing neck masses. Ultrasound can assist in identifying unclear nasopharyngeal masses. After treatment, neck masses often resolve, and surgery may not be necessary; unnecessary surgery could adversely affect outcomes.
