[Sonography of the head and neck area - Part 1: Endosonography]. / Sonografische Diagnostik im Kopf-Hals-Bereich ­ Teil 1: Endosonografie.

Sonography of the head and neck area plays a major role in both outpatient and inpatient ear, nose and throat medicine. Transcervical ultrasound is an important imaging method, especially in lymph node and tumor diagnostics. Its advantage is the ubiquitous availability and the excellent combinability with endoscopy and palpation. Despite decades of experience with sonography in the head and neck area, in contrast to the transcutaneous application, the transoral or endosonographic approach has so far not been widely used. Here it is often not due to the technical capabilities of the examiner, but rather to the unusual approach within the scope of the investigation. In this context, endosonography may be used primarily in tumor diagnostics in order to establish a complete sonographic examination from in- and outside.
