We encountered a case where a 30 gauge disposable dental needle was accidentally broken and inoculated into pterygomandibular space by a dentist during a block anesthesia for the inferior alveolar nerve. Several approaches including use of a guide needle and roentgenograms were made but all were unsuccessful. Eleven days later, further operation was attempted monitoring the needle on X-ray TV, resulting in that the broken needle was successfully removed. This technique may be useful for removal of mandibular broken needles.
一名牙医在进行下牙槽神经阻滞麻醉时，不慎将一根30号一次性牙科针折断并刺入翼下颌间隙。尝试了包括使用引导针和X光片在内的几种方法，但均未成功。11天后，尝试在X光电视监测下进一步手术，最终成功取出了折断的针头。该技术可能有助于取出下颌折断的针头。
