    Abstract:
    Hunter syndrome, manifested by mucopolysaccharidosis II (MPS II), is a hereditary disorder caused by accumulation of glycosaminoglycans. An important issue in regard to anesthesia in affected individuals is airway management, because of gargoylism. An 8-year-old boy with MPS II was scheduled for adenotonsillectomy. We performed slow induction with sevoflurane, then utilized an Airway Scope (AWS; HOYA Corporation Tokyo, Japan), which enables operators to observe tube passage through the vocal cords with an LCD monitor, for tracheal intubation, because intubation guided by a fiberoptic bronchoscopy (FOB) was considered to be risky for glottic damage. Attempted tracheal intubations with the AWS alone and in combination with an FOB inserted through the tracheal tube failed, even though a clear image of the glottis was obtained. Finally, we inserted a stylet into the tracheal tube attached to the blade of the AWS and successful tracheal intubation was accomplished. The operation was completed uneventfully and the patient entered the ICU with his trachea intubated, because of pharyngeal and laryngeal edema. Although useful for difficult airway management, tracheal intubation with the AWS may be difficult when used in patients with a narrow oral cavity or small tracheal tube.
