Eligible participants with chronic tympanic membrane perforation (\>6 month) will be given a detailed description and offered to participate in the study. the study investigates the efficacy of trans canal tympanoplasty with local anesthesia using fat pad and "Tachosil". Participants will be followed for 1 year after the procedure with otological examination and successive hearing evaluations.

Under local anesthesia, subcutaneous fat from the neck will be harvested. After that trimming of the perforation edges, planting the fat graft medial to the tympanic membrane and placement of the "Tachosil" on top of the fat graft. gelfoam is placed lateral to the tympanic membrane to fill the ear canal. follow-up will be held at 2, 4-6 and 12 months following the procedure, with audiometric and otological evaluation
closure of tympanic membrane perforation
the effectiveness of the tympanoplasty using far graft and "Tachosil" will be evaluated - whether close of tympanic membrane perforation occured.
Time frame: 1 year following the procedure
Hearing results following tympanoplasty - Speech recognition threshold
SRT (Speech recognition threshold) in dB (Decibel) will be evaluated pre and post tympanoplasty using an audiogram.
Time frame: 1 year following the procedure
Hearing results following tympanoplasty - Pure Tone Average
PTA air and PTA bone (Pure Tone Average) in dB (Decibel) will be evaluated pre and post tympanoplasty using an audiogram.
Time frame: 1 year following the procedure
Hearing results following tympanoplasty - air bone gap.
Air-bone gap in dB (Decibel) will be evaluated pre and post tympanoplasty using an audiogram.
Time frame: 1 year following the procedure
