1 Cases of isolated hypoglossal nerve
palsy without any accompanying neurological symptoms are very rare, and are classified as idiopathic if a clear cause is not found.
Treating obstructive sleep apnea with hypoglossal nerve
Unilateral hypoglossal nerve
palsy due to neurovascular conflict in a child.
Treatment, which delivered unilateral stimulation of the hypoglossal nerve
, "synchronous with ventilation, resulted in significant and clinically meaningful reductions in the severity of sleep apnea and self-reported sleepiness and improvement in quality of life measures at 1 year" (N.
(XII n) recordings were obtained by suctioning the nerve with a suction electrode and amplified with a differential amplifier.
The pacemaker-like device monitors breathing patterns and is activated during sleep to stimulate the hypoglossal nerve
, which controls muscles in the upper airway.

However, invasive procedures of the neck carry the risk of pneumothorax, hematoma formation, vagus or hypoglossal nerve
damage, and wound infection.
Growth of the hypoglossal canals in the human lineage may have accompanied a thickening of the hypoglossal nerve
to coordinate tongue movements needed for speaking, Kay's group theorized.
It is important to note that nerve injury after CEA may be temporary and most often involves the 11th cranial nerve, the hypoglossal nerve
Though there are several new neurostimulation devices competing in the market for treating OSA, we selected ImThera's aura6000 because of its ability to deliver targeted hypoglossal nerve
stimulation to achieve optimal muscle stimulation.
