227 tympanoplasty III type surgeries were operated in 2010–2012 in Mongolia. Clinical and operative features of the tympanoplasty III type surgeries were prospectively recorded. Out of the surgeries, 98 cases (43.2%) were cholesteatoma, 101 cases (44.5%) were granuloma middle ear and 29 cases (12.3%) were adhesive otitis media.

Regarding middle ear diseases, 16,2% out of the diseases have the defect of malleus, 44,1 % have the defect of incus and discontinuity of incus and stapedius, and 39,7% is totally absent of ossicular chain.

The air and bone gap of all patients were above 15–35 dB. HEINZ KURZ firm’s TTP-Variac system’s titan prosthesis was used.

Titan prosthesis PORP was carried out in 137 cases (60,4%). For 67 (48,9%) out of the 137 cases, size of titan prosthesis PORP 2.25 mm was chosen. Hearing level increased for 72% out of patients by 10–25 dB after the operation. However, for 70 (51,1%) out of the 137 cases, size of titan prosthesis PORP 2.5 mm was chosen. Hearing level increased for 89% out of patients by 10–30 dB after the operation. Titan prosthesis TORP size 4–4.25 mm was chosen for 90 (39,6%) out of 227 cases. Titan prosthesis with connector was used for 18 out of 90 cases.

Hearing level increased by 10–30 dB for 82% out of patients involved after the operation. Implantation of Titanium prosthesis increased hearing capability by 80–86% dB.
