Airway patency in both children and adults depends on the tonic and phasic activation of muscles of the tongue and pharynx supplied by the hypoglossal nerve arising at the medullary level


We report a case of a 2-year-old who after resection of fourth ventricle anaplastic ependymoma developed severe sleep disordered breathing and tongue fasciculation.


Polysomnography showed severe obstructive sleep apnea with oxygen desaturation to 33%. Magnetic resonance imaging of the brain showed post-surgical effacement of the dorsal lateral medulla.


We postulate that damage to the hypoglossal nerve at the level of the medulla contributed to the patient's severe obstructive sleep apnea. Patient was treated with tracheostomy.
