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.
尽管在牙科操作中断针的发生率很低，但由于制造缺陷、患者管理不当或医生技术欠佳，仍可能发生断针情况。取出断针不仅是因为断针有移位的可能，还出于心理和法医学方面的考虑。本病例报告描述了在局部麻醉尝试过程中折断的牙科针的手术取出过程。确定断针碎片的确切位置及其与周围骨骼、血管和神经的关系对于设计适当的治疗方案至关重要。如果需要进行手术取出，应立即进行，尤其是在针碎片未弯曲或变形的情况下。在本病例中，使用C形臂荧光透视辅助手术取出，节省了时间并降低了治疗成本。
