Material and Methods: In this retrospective study, 103 patients (mean age of 37.16±13.14 years) were enrolled. Patients were divided into groups according to the graft materials (cartilage or perichondrium) and the surgical techniques (underlay or over-underlay). Anatomical and audiological outcomes were compared.

Results: There was no statistically difference in the surgical techniques. The graft was intact in 58 (90.6%) patients in the underlay group, in 31 (79.5%) patients in the over-underlay group. There was no statistically significant difference between the cartilage (92.2%) and the perichondrium (80.8%) groups (p?0.05). The pre-operative and post-operative air-bone gap values were statistically significantly different in all patients and each perichondrium, cartilage, underlay, over-underlay group (p<0.05). ABG values in all frequencies and in 1000 Hz the cartilage group was statically significantly different from the perichondrium group (p?0.05). There were significant differences in the cartilage, perichondrium, and underlay groups in 4000 Hz. But there was no statistical difference in the over-underlay group at 4000 Hz.

Conclusions and Significance: After learning curve, transcanal endoscopic tympanoplasties can be performed successfully with different graft materials and different surgical techniques. Keywords : Endoscopic tympanoplasty, cartilage, perichondrium, underlay, over-underlay
