Foreign body removal assisted by an intraoral ultrasound probe


Ultrasonography has recently been applied to the field of oral and maxillofacial surgery because of its noninvasiveness and ease of use. However, traditional transducers are not used in the intraoral area because of their large size. A novel intraoral transducer was introduced with size, volume, and axis modifications. This new transducer allows the surgeon to approach the intraoral region during dental procedures. This report describes a case of successful removal of a foreign body using the newly developed intraoral ultrasound probe. Precise localization and minimally invasive removal of the foreign body using the intraoral transducer were simultaneously conducted. Because of its many advantages, this intraoral ultrasound transducer has the potential to be applied in oral and maxillofacial surgery.
