We describe an intraoral foreign body that had not been noticed for a long time in a 9-year-old girl.When she was 1-year old, she mistakenly swallowed sewing needles.Some of them were removed with the use of an enema.However, further examination was not performed at that time.Subsequently, she had no symptoms for 8 years.Another needle-like radiopaque object was discovered by chance on an X-ray film.We confirmed that the object was situated in the right medial pterygoid muscle by computed tomographic and fluoroscopic examination.We removed it by an intraoral approach.
