Hypoglossal nerve stimulation and airway changes under fluoroscopy.
OBJECTIVE To characterize the changes in the anteroposterior dimensions of both the retropalatal and retrolingual airway spaces of the pharynx and hyoid bone position during hypoglossal nerve stimulation under general anesthesia in subjects with obstructive sleep apnea. STUDY DESIGN Cross-sectional. SETTING Academic center. SUBJECTS AND METHODS Cross-table fluoroscopic images obtained dur...
متن کاملElectrical stimulation of the hypoglossal nerve: a potential therapy.
Obstructive sleep apnea is characterized by recurrent episodes of pharyngeal collapse, which result from a decrease in pharyngeal dilator muscle tone. The genioglossus is a major pharyngeal dilator that maintains airway patency during sleep. Early studies in animal and humans have demonstrated that electrical stimulation of this muscle reduces pharyngeal collapsibility, increases airflow, and m...
متن کاملPostsynaptic potentials in the hypoglossal motoneurons set up by hypoglossal nerve stimulation.
In nembutalized cats intracellular potentials were recorded from hypoglossal motoneurons innervating either protruder or retractor muscles of the tonge (protruder and retractor motoneurons: P-Mns and R-Mns). Responses to stimulation of the hypoglossal nerve were explored and found to consist of an antidromic spike followed by an afterhyperpolarization (AHP) and a postsynaptic potential (PSP). W...
متن کاملHypoglossal nerve stimulation improves obstructive sleep apnea: 12-month outcomes.
Reduced upper airway muscle activity during sleep is a key contributor to obstructive sleep apnea pathogenesis. Hypoglossal nerve stimulation activates upper airway dilator muscles, including the genioglossus, and has the potential to reduce obstructive sleep apnea severity. The objective of this study was to examine the safety, feasibility and efficacy of a novel hypoglossal nerve stimulation ...
متن کاملImaging the hypoglossal nerve
The hypoglossal nerve is a pure motor nerve. It provides motor control to the intrinsic and extrinsic tongue muscles thus being essential for normal tongue movement and coordination. In order to design a useful imaging approach and a working differential diagnosis in cases of hypoglossal nerve damage one has to have a good knowledge of the normal anatomy of the nerve trunk and its main branches...
