Imaging Features of Mucopolysaccharidoses in The Head and Neck............Ear, Nose and Throat (ENT) involvement by mucopolysaccharidoses is very common, affecting over 90% of patients, and occurs early in the course of the disease. Airway narrowing secondary to glycosaminoglycan deposition results in greatly increased morbidity, mortality and risk of anesthetic complications in these patients. Macroglossia, restricted mouth opening, tracheobronchomalacia, adenotonsillar hypertrophy along with other factors such as a short, rigid and unstable cervical spine, cardiac disease and increased susceptibility to respiratory infections result in a high perioperative mortality and morbidity. Imaging is most beneficial for evaluation of the airway, in particular in patients with obstructive symptoms and prior to intubation. We review the ENT manifestations of mucopolysaccharidoses including airway involvement, otological, oral and dental complications. 3-D reconstructions of the trachea, which is routinely captured on CT imaging of the spine, can be of great value for planning intubation in this patient population.
