Intraoperative ultrasound to facilitate removal of a submucosal foreign body

ABSTRACT A 61‐year‐old man with a history of fish bone ingestion and poorly localized symptoms was seen. His clinical examination was unremarkable, but CT demonstrated a foreign body deeply embedded within his tongue. Intraoperative ultrasound (US) guidance facilitated identification of a bone, allowing a needle to be placed as a guide to dissection. Repeat US scanning through the incision permitted precisely targeted surgery. CT and US are the most effective imaging techniques for localizing fish bones. Intraoperative US can be used to accurately locate a submucosal fish bone in mobile tissue such as the tongue, and focused, image‐guided dissection can reduce surgical tissue trauma. © 2014 Wiley Periodicals, Inc.
