title: [Interpretation of ultrasound findings in otorhinolaryngology. Salivary glands, paraganglioma, angioma, esophagus, hypopharynx, extra cranial vessels and temporomandibular joint].
abstract: The second part of this continuing medical education article focuses on sonographic assessment of the salivary glands, cervical paraganglioma, angioma, esophagus, extra cranial blood vessels and the temporomandibular joint. The currently available minimally invasive therapeutic options (e. g. sialendoscopy, lithotripsy, therapeutic duct lavage and extracapsular dissection) for salivary gland disease presuppose a precise imaging modality. Modern ultrasound is able to meet this challenge, making additional imaging a rare necessity. Regions of the neck with a difficult topography (esophagus and hypopharynx) can often be successfully portrayed sonographically. Furthermore, ultrasound enables functional evaluation of swallowing in the cervical parts of the esophagus in dysphagia patients. In addition to the branchial cleft anomalies and lymph nodes discussed in part 1, paraganglioma, angiomatosis and neurogenic tumors are important differential diagnoses of solid lesions of the neck. Finally, venous and arterial alterations of the extracranial vessels of the neck relevant to clinical routine are depicted, as are pathological conditions of the temporomandibular joint relevant to the otorhinolaryngologist.
