What to do if i have obstructive sleep apnea. will a tonsillectomy completely improve my quality of life?

It depends: Although miracles can happen after a tonsillectomy(just had a patient who i did tonsillectomy for and her AHI went from 66 to 3), the likelihood of getting rid of sleep apnea is not high with only a tonsillectomy. You will need to be examined for the cause of sleep apnea and the severity. Your chances of success are better if you have a mild sleep apnea,but for severe tonsilectomy unlikely to cure

Not likely: Sleep apnea is due to obstruction of the oropharyngeal airway usually at the level of the tongue or epiglottis. Two-thirds of patients with OSA are overweight and fatty infiltration of the neck and tongue may also contribute to airway obstruction during sleep.

Perhaps: OSA anatomical problems are often multifactorial. Removing tonsils will help. Degree of improvement depends on how much that component contributes to the OSA. Other procedures may be indicated. Good question to ask your ENT doc.
