Episode notes
ENT's Broad Role In Sleep Breathing
- ENT surgeons treat the entire upper head and neck region beyond ears and tonsils.
- Sleep surgery spans the nose, palate, tongue, epiglottis and even jaw work to improve airway.
Faces Narrowing Drives Airway Problems
- Modern faces and jaws have narrowed over generations due to softer diets and utensils.
- Narrower jaws reduce airway space and increase sleep breathing problems, says Steven Y. Park.
UARS Fragmentation Harms Hormones
- Upper airway resistance (UARS) causes repeated flow limitations without meeting apnea thresholds.
- That sleep fragmentation raises stress hormones and harms cognition, mood, digestion and endocrine function.
