Suffering from chronic sinusitis since 3-4 years. only one nostril is blocked while sleeping.used every type of nasal spray. doc says its b/l inferior turbinate hypertrophy and suggests that i might need smd surgery, can it return even after surgery?

Yes, it may return. It really depends on if the hypertrophy plays a more significant role than another possible cause of the sinusitis, such as allergy. If it's more of a structural issue, then surgery may help. But if it's more likely due to another cause, then the surgery may not help.

I understand how difficult those symptoms are for you. I presume you have tried daily nasal rinses/Netipot? Be sure fully tested for allergies. If they are found, treat those before considering surgery. I am not a surgeon, but if allergies are not involved, many of my patients find many years of relief after a procedure. But your surgeon should be able to give you their estimates. Good luck

You should ask the surgeon as they will know how to make a prediction in patients like you that they have operated on in the past.
