Unit of randomization: individual
Tools used in randomization: table of random numbers.
 patient assignment in groups A and B will be done based on a completely randomized design. 
To prevent bias in our study a double-blind design will be performed. Both analgesics are in separate boxes A and B, and only the ENT specialist is aware of the drug's content in each group, Blinding description: Patients will be treated with prescribed medication packages by an ENT specialist. Drug packages are quite similar in shape, and the patient and project manager are unaware of the contents of the packages. Data gathering, patient analysis and filling the forms will be done by investigator and the assistant who are not aware of the contents of the packages; In the data analysis step, the analysis will be done by the project advisor and the investigator, who are not aware of the contents of the drug packages, and  groups of patients (groups 1 or 2) will be defined for the data analysis. Therefore, the study is a double blind study and from the stage of the patient's entry into the study to the study phase, data collection and data analysis, the contents of the two drug groups are not clear.</study_design>
