In this way, random sequences are produced in 15 blocks of 6 and patients will be divided into A or B groups based on the order of the generated sequences. Concealment is done by using non-transparent sealed envelopes in such a way that a number of envelopes with aluminum cover are prepared and each of the random sequences created is recorded on a card. The cards are placed in the letter envelopes in order. In order to preserve the random sequence, the outer surface of the envelopes is numbered in the same order. At the start of the study, according to the order of entry of the participants, one of the letter envelopes will be opened and the assigned group of that participant will be revealed, Blinding description: Blinding in this study will be double-blind. In this way, patients will not know about the type of surgery performed. Also, the project administrator, who is responsible for evaluating patients and recording information, and the statistical consultant of the project, who is responsible for data analysis, will recognize patients only through groups A and B. Only the project surgeon who is responsible for performing tympanoplasty surgery for the patients will know about the study groups. 3 Perforation of tympanic membrane. Intervention 1: Control group: In the control group, patients will undergo tympanoplasty surgery through the back of the ear using Gelfoam by the same surgeon as the intervention group. Intervention 2: Intervention group: In the intervention group, patients will undergo tympanoplasty surgery through the back of the ear using fibrin glue by the same surgeon as the control group.
