To group patients in a simple random way, the letters A, B and C are written on 60 pieces of paper with equal dimensions (each letter is written on 20 pieces of paper). After entering, each patient selects one of the papers with an equal chance and thus the patient group is determined, Blinding description: The patient is not informed that he or she is in the control or sample group. The specialist who performs rhinomanometric tests on patients before and after surgery is unaware of those in the control or sample group.
