GENIOGLOSSUS STIMULATION DOES NOT HELP SLEEP APNEA

THE STUDY "STATE-DEPENDENT EFFECTS OF GENIOGLOSSAL STIMULATION ON UPPER AIRWAY" BY Buterbaugh J1, Ahmed O2,3, Wynstra C1,3, Morrison-Barrios M, Koebnick J1, Parthasarathy S SHOWED THAT STIMULATION OF THE GENIOGLOSSUS MUSCLE WHICH INCREASED AIRWAY DIMENSION IN AWAKE PATIENTS WERE NOT RELATED TO REDUCTIONS IN SLEEP-RELATED BREATHING DISORDERS AT NIGHT. THE AUTHORS POSTULATE THAT THERE ARE OTHER FACTORS THAT DETERMINE NOCTURNAL AIRWAY.

ACOUSTIC PHARYNGOSCOPY IS FREQUENTLY USED TO EVALUATE AIRWAY SIZE BASED ON ACOUSTIC ECHOES. THIS STUDY WOULD PROVOKE QUESTIONS AS TO THE VIABILITY OF THOSE AWAKE MEASUREMENTS FOR EVALUATING A SLEEP DISORDER. THIS IS NOT TO SAY THAT ACOUSTIC PHARYNGOSCOPY DOES NOT HAVE A ROLE TO PLAY BUT RATHER TESTING OF TREATMENT EFFECTIVENESS MUST BE DONE DURING SLEEP.
