Migration and surgical retrieval of a broken dental needle: a literature review and case report

Abstract

Although the incidence of broken needles in dental practice is minimal, needle breakage can occur as a result of manufacturing defects, inadequate patient management, or poor practitioner technique. Retrieval of a broken needle is justified not only because of the potential for needle migration but also because of psychological and medicolegal considerations. This case report describes the surgical removal of a dental needle that fractured during an attempt at local anesthesia. Identifying the precise location of the broken needle fragment and its relationship with the surrounding bones, vessels, and nerves is essential to designing an adequate treatment plan. If surgical retrieval is indicated, it should be performed immediately, especially in cases in which the needle fragment has not been bent or deformed. In the present case, the use of C-arm fluoroscopy aided the surgical removal while saving time and reducing the cost of treatment.
