Abstract
PURPOSE
To discuss potential causes of broken dental needles during dental anesthesia and features of this complication, including the anatomical location of fragments in tissues, symptoms, complications, and therapeutic approaches.
METHODS
Twelve cases of broken dental needles occurring during dental anesthesia and subsequently referred to Hospital de Base do Distrito Federal, Brazil, between 1992 and 2019 were selected. In addition, similar cases reported in the literature over the past 50 years were reviewed.
RESULTS
Needle fractures occur most frequently during inferior alveolar nerve blocks and in younger patients. The leading cause is unexpected patient movement during the anesthetic procedure. The needle fragment is most commonly found in the pterygomandibular space or the deep spaces of the head and neck region. Needle migration is a particular concern; although rare, it is unpredictable and potentially life-threatening.
CONCLUSIONS
Needle fracture is an intraoperative complication which has the potential to cause severe patient damage. It is essential that practitioners have knowledge of this possible complication and understand the technical considerations for its prevention. The existing literature and the results of this case series analysis suggest that removal of the fractured needle fragment should be attempted as soon as possible.
