A rare case report and review of the literature: partial Horner's syndrome and unusual neurological complications after inferior alveolar nerve block.

Background: Inferior alveolar nerve block (IANB) is frequently applied in mandibular dental procedures. Neurological complications develop very rarely due to IANB, and most of the complications are temporary. Case Presentation: We present a 79-year-old man with partial Horner's syndrome, hyperlacrimation, aphonia, dysphagia, severe cough, and foreign body sensation in the throat after IANB. All symptoms disappeared 3 hours after local anesthetic injection. Conclusion: It was aimed to investigate the underlying pathophysiological causes of complications together with clinical and anatomical data. Neuronal blockade of the carotid plexus, nervus laryngeus superior and inferior can develop after IANB. In addition, it is critical to accurately determine the IANB injection site in obese and thick-short neck patients. [ABSTRACT FROM AUTHOR]
