A technical note: pre-operative ultrasound-guided wire localization in head and neck surgery.

Ultrasound-guided wire localization of impalpable lesions is a well-recognized technique in the management of breast pathology, but its use in the head and neck is not well described. Performed under local anesthesia, high-resolution ultrasound provides real-time imaging for accurate placement of the wire resulting in fewer complications. Wire localization can focus the surgical approach, which reduces operating time and minimizes trauma to surrounding tissues. In this technical note, we describe two cases of pre-operative ultrasound-guided wire localization to facilitate the surgical excision of impalpable neck lesions.
