다국어 초록 (Multilingual Abstract)

Ligamentous ossification of the anterolateral spine is characteristic of diffuse idiopathic skeletal hyperostosis (DISH; i.e., ankylosing hyperostosis or Forestier’s disease). Cervical spine involvement can make airway management difficult during intubation. A patient with a history of impossible intubation resulting from the presence of large anterior cervical osteophytes presented for removal of the osteophytes. Preoperative diagnostic imaging revealed a larynx anteriorly displaced by osteophytes. The osteophytes were on the anterior surfaces of the third to seventh cervical vertebrae. Successful intubation was performed using an angulated curved video laryngoscope and a back-up head-elevated position (BUHE). The angulated curved video laryngoscope and BUHE position provided a good laryngeal view in a patient with DISH who had a larynx with osteophyte-associated anterior displacement. We suggest that these methods are an alternative for anesthesiologists during airway management of patients with difficult intubation.
