Airway management for patients with ossification of the anterior longitudinal ligament of the cervical spine

Le résumé fourni par la source

Ossification of the anterior longitudinal ligament (OALL), also called Forestier's disease or diffuse idiopathic skeletal hyperostosis, is characterized by anterior bridging osteophytes of unknown etiology. OALL may cause dysphagia, dyspnea, dysphonia, and acute airway obstruction. We report difficulty in tracheal intubation during anesthesia induction in two OALL patients. In an 82-year-old man, anterior bridging osteophytes (of the cervical region) were observed on preoperative lateral radiograph after several attempts of tracheal intubation for the operation of the anterior fusion of cervical spine. During the same procedure in another 69-year-old man, fiberoptic-assisted awake intubation was extremely difficult because of posterior hypopharyngeal wall protuberance by osteophytes of cervical spine; although tracheal intubation for anesthesia was uneventful on two previous occasions over the months. OALL is usually asymptomatic, but it has been found in 12 % of autopsies and may exaggerate with age. Dysphagia, difficulties with tracheal and/or gastric intubation, acute respiratory compromise, and sleep apnea result from the presence of cervical osteophytes. Anesthesiologists should be aware that tracheal intubation for such patients may be difficult, and thus the preoperative evaluation and airway management need careful consideration.
