Key Points:

We describe a novel procedure, Endopharyngeal Ultrasound (EPhUS) and EPhUS-guided FNA
EPhUS requires an operator and an assistant, can be performed transnasal or transoral, and utilizes a Endoscopic Ultrasonography Bronchoscope
EPhUS is a safe and effective method for biopsy of deep space neck masses inaccessible to transcutaneous FNA
