For each patient case (for the description of the cases, see Supplementary File 1), the members of the Finnish Otosurgical Society and the residents present in the meeting voted if they thought that BET was indicated or not or whether they were unable to decide. The votes were divided to three groups according to if the person voting was an ENT specialist routinely performing BET, an ENT specialist not routinely performing BET, or an ENT resident.
