Fractured needle as an unusual complication of the lingual nerve block: a case report
Aras Erdil,Mustafa Sami Demirsoy,Sefa Çolak 대한치과마취과학회 2022 Journal of Dental Anesthesia and Pain Medicine Vol.22 No.4
Although rare, hypodermic needle fractures can occur in the maxillofacial region. In cases of fracture, urgent intervention is required to prevent further complications. We present the case of a 37-year-old female patient with a fractured needle in the left sublingual fossa during a lingual nerve block 6 months before referral. The fragment of a 30-gauge needle was located using cone-beam computed tomography and retrieved under local anesthesia with blunt dissection. The patient recovered uneventfully, except for predictable postoperative inflammatory complications, which resolved within 2 weeks. Precautions should be implemented to prevent needle fractures, which are usually preventable. However, if the retrieval is unsuccessful, the patient should be referred to a well-equipped surgical unit without delay.
