First report of accidental displacement of mandibular third molar into infratemporal space.

摘要

One of the most common procedures in the dental office is surgical removal of the maxillary or mandibular third molars. Of the complications associated with third molar extraction, the most commonly mentioned have been dysesthesia, alveolar osteitis, infection, hemorrhage, fracture of the mandible, and damage to the adjacent teeth. Accidental displacement of the fractured roots or teeth into the submandibular, pterygomandib-ular, and sublingual spaces is a less common complication. One of the very rare occurrences during mandibular third molar extraction is displacement of the tooth into the infratemporal space, such as reported in the present study. A review of the published data revealed little information on the incidence, cause, and management of displaced tooth and root fragments.
