Anesthetic Management of a Patient With Myhre Syndrome

Myhre syndrome (MS) is a rare genetic connective tissue disorder characterized by intellectual disability, growth deficiency, muscular pseudohypertrophy, hearing loss, restricted joint mobility, laryngotracheal stenosis, choanal stenosis, and facial deformities. We encountered a case of difficult endotracheal intubation in a patient with MS. A 17-year-old girl with trismus, macroglossia, and difficulty with neck flexion was scheduled to undergo general anesthesia for dental treatment. Because of these characteristic clinical manifestations, endotracheal intubation was performed with a flexible fiber-optic bronchoscope. When providing general anesthesia for patients with MS, preoperative evaluation of the airway and preparation for potentially difficult tracheal intubation are required.
