THE ULTRASOUND UTILITY FOR THE OPERATION OF TRAUMATIC DEEP SUBMANDIBULAR FOREIGNBODY

Abstract

A 22-year-old man experienced a traumatic deep submandibular foreignbody in a traffic accident. Roentgenogram did not indicate its position clearly, and extraction was tried three times with no success. On using 7.5 MHz high speed mechanical sector scanner, the foreignbody was removed easily. The mechanical sector scanner and linear electric scanner can produce real time images, but they are not available for superficial tissue. In this case a mechanical arch scanner was used because of the advantage of its high resolution when use on superficial tissue.
