High resolution ultrasonography of the parotid gland in children
High resolution ultrasonography has revolutionized imaging of the superficial parotid gland. The fine morphology of the parotid gland can be exquisitely visulized. Anatomical landmarks such as the mastoid tip, the sternocleidomastoid muscle, the styloid process, the posterior facial vein, the internal jugular vein, and the external carotid artery can easily be identified in relationship to the parotid. The course of the facial nerve can be inferred by visualization of these landmarks. Common masses within the parotid in children such as hemangiomas, mixed parotid tumors, and lymphadenopathy can be demonstrated. Parotid masses are uncommon in children but can be easily evaluated by high resolution ultrasonography.
