Purpose: In this study, the aim is to compare the different grafting materials and different grafting techniques used in patients with endoscopic timpanoplasty. In our study, a total of 103 patients who suffered endoscopic timpanoplasty surgery (the average age 37.16±13.14) were retrospective. Patients were divided into groups according to the graft materials used during the operation (kartillage or pericondrium) and according to the surgical techniques used during the graft (underlay or over-underlay). The success of holding the greft between the groups and the odyological results were compared. Results: In all patients, the success of holding the greffe was 86.4 percent (89/103). There is no statistically meaningful difference between the surgical techniques applied in terms of success of greft holding and the used greft materials. Underlay technique was used in the group of 58 patients (90%) and over-underlay technique was used in the group of 31 patients (79,5%) were found in the group of infection. In the group used for cartilage, 92.2 per cent, pericondrium in the group used, 80.8 per cent of the group used for the infection (p.0.05). In all groups, preoperative and postoperative air bone marrow (HKY) values showed statistically significant changes (p<0.05). When preoperative and postoperative HKY for each frequency were evaluated separately, the group used for cartilage greft at 1000 Hz was statistically meaningful from the group used pericondrium (p0.05). While there is a significant difference in the 4000 Hz cartilage, pericondrium and underlay techniques applied groups, there is no significant difference in the over-underlay techniques applied groups. After a certain learning process, endoscopic timpanoplasty can be successfully applied using different graft materials and different graft techniques.
