Use of sialendoscopy as an aid to identify a large retained foreign body.

We describe the novel use of sialendoscopy in a 51-year-old man to identify a large and long-standing foreign body (wood) within the facial soft tissues that had eluded detection on previous imaging and surgical exploration. The identification of this foreign body was elusive on both computed tomography and magnetic resonance imaging, illustrating the limitations of imaging in identifying vegetable matter within soft tissues.
