Task: Answer Verification
Input (English): Question: Do total IgE levels change 1 year after endoscopic sinus surgery in patients with chronic rhinosinusitis?
Answer: The levels of total serum IgE do not change after sinus surgery for chronic rhinosinusitis. IgE levels in chronic rhinosinusitis may reflect a systemic factor in disease pathogenesis, and are probably not related to the amount of local inflammation within the sinuses.
Output (English): no
