Diagnosis by dynamic MRI in sleep disordered breathing.
According to the obstructive site, different types of obstructive type sleep disordered breathing are classified as the soft palate type, palatine tonsil type, soft palate and depressed lingual root type, depression of the lingual root type, and epiglottis type. In this study, we conducted dynamic MRI examinations of the oral and pharyngeal and lingual root sites in patients with obstructive sleep disordered breathing, and studied MRI's usefulness as a diagnostic tool in the examination of such obstructive sites. In this paper, we present mainly the adult cases of patients with obstructive sleep disordered breathing which appeared to be caused by an enlarged palatine tonsil.
