Accidental displacement of an impacted
tooth into the infratemporal fossa (ITF) is a rare but serious complication
because of the vulnerability of the surrounding anatomical structures. Here we
present the case of a 40-year-old man who reported pain on the right side of
his face. Panoramic radiography and cone-beam computed tomography revealed an
impacted third molar and a supernumerary tooth positioned immediately below it.
Under local anesthesia, the third molar was easily extracted; however, the
supernumerary tooth was inadvertently displaced into the ITF. The position of
the tooth was confirmed by radiographic examination, and it was immediately
removed intraorally by expanding the flap and carefully dissecting the soft
tissues. Clinical aspects of this rare complication were evaluated, with
special emphasis on the reliability of imaging modalities and surgical
techniques.
