[Compression of a nasotracheal tube in the nasal cavity of a patient with craniofacial fibrous dysplasia].

A 42-year-old woman with craniofacial fibrous dysplasia underwent osteoplasty of maxillary and mandibular bone. Preoperative CT images showed osteosclerosis and ground glass appearance of the right side of the skull including the orbit, temporal bone, paranasal sinus, and maxillary and mandibular bones, as well as hypertrophy of the nasal septum. Inhalation anesthesia was induced and 8.0-mmID polyvinyl chloride endotracheal tube was inserted via the left nostril with slight resistance. At emergence, a 10-Fr suction catheter could not be passed throgh the tube but an 8-Fr nasogastric tube could be passed. A part of the tube positioned in the nasal cavity was apparently compressed. Preoperative examination of the nasal cavity and nasal septum using CT or MRI may be desirable for nasotracheal intubation in the patients with craniofacial tumor, and the application of a spiral reinforced endotracheal tube may contribute to prevent such cases of airway obstruction in the nasal cavity.
