Outcome Measures

Primary Outcomes (2)

  • Modified Lund-Kennedy endoscopic score

    The modified Lund-Kennedy score is an endoscopic score that measures sinus involvement during endoscopy. It is divided into 2 nostrils. For each nostril, it has a score of 0 to 2 for the presence of polyp, edema and flow. The score is therefore 0 to 6 for each nostril for a maximum of 12. The higher the score, the more severe is the condition

    3 months

  • Quality of life of patients SNOT-22

    The SNOT-22 score is a quality of life score. It contains 22 sinus symptoms. Each of the symptoms is scored from 0 to 5, with 0 being no problem and 5 being a severe problem. The SNOT-22 is a score of 0 to 110, the higher the score, the more severe the disease.

Intervention Model
PARALLEL
Model Details: During the surgery, 4 groups will be formed as described in the figure below. Patients will be divided according to the presence or absence of polyps at the endoscopy and randomized in one of the 2 groups by the pharmacy of the CHU of Quebec. This will give either a prescription of Clavulin 875 mg per os to be taken twice a day for 10 days, or a placebo of similar visual appearance according to the same dosage
