[Ultrasound-guided minimally invasive diagnostics and treatment in the head and neck area]

Tumoral lesions in the head and neck region represent a diagnostic and therapeutic challenge in otorhinolaryngologic routine. High-resolution ultrasound is usually able to guide diagnosis. Nevertheless, a definite differentiation between benign and malignant lesions can only be achieved by tissue biopsy. The various options for obtaining samples for histopathological or cytological examination-from minimally invasive ultrasound-guided fine-needle biopsy to punch biopsy and open surgical biopsy-will be discussed in the first part along with the associated advantages and disadvantages. In the second part of this CME article, minimally invasive ultrasound-guided therapeutic options in the head and neck region which can be performed on an outpatient basis are depicted.
