Abstract:
Among world population, 23.4% have different kinds of hearing disorders and 56% are middle ear disorders, 30% are inner ear disorder, 10% are congenital deaf and 4% are congenital mixed outer and middle ear disorder (WHO info, 2006).In 1995, by the German research, 2% of newborn babies were deaf therefore, among children from 1-18, 16% had middle ear disorder and 0.8% had inner ear disorder. In most cases (54%) cause of hear loss and deaf as sound transmitting apparatus. Later in 2010, sound transmitting apparatus related disorder was decreased by 22.4% J.Helms1995 , K.Schwager 2010 . Doctors proved that 62% of sound transmitting apparatus related disorders are 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 120 tympanoplasty III type surgeries were operated in 2011-2013 in Mongolia. Clinical and operative features of the tympanoplasty III type surgeries were prospectively recorded. Aim: To recover sound transmitting related hear loss with titan prosthesis implant. 120 tympanoplasty III type surgeries were operated in 2011-2013 in Mongolia. Clinical and operative features of the tympanoplasty III type surgeries were prospectively recorded. Out of the surgeries, 51 cases (42.5%) were cholesteatoma, 53 cases (44.2%) were granuloma middle ear and 16 cases (13.3%) were adhesive otitis media. The air and bone gap of all patients were above 15-35 dB. HEINZKURZ firm’s TTP-Variac system’s titan prosthesis was used. Titan prosthesis PORP was carried out in 86 cases (71.6%). For 40 (45.5%) out of the 86 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 46 (54.5%) out of the 86 cases, size of titan prosthesis PORP 2.5 mm was chosen. Hearing level increased for 82% out of patients by 10-30 dB after the operation. Titan prosthesis TORP size 4-4.25 mm waschosen for 34 (28.4%) out of 120 cases. Hearing level increased by 10-30 dB for 80% out of patients involved after the operation Out of the surgeries, 51 cases (42.5%) were cholesteatoma, 53 cases (44.2%) were granuloma middleear and 16 cases (13.3%) were adhesive otitis media.Titan prosthesis PORP was carried out in 86 cases (71.6%). For 40 (45.5%) out of the 86 cases, size oftitan prosthesis PORP 2.25 mm was chosen. Hearing level increased for 72% out of patients by 10-25 dB after the operation. However, for 46 (54.5%) out of the 86 cases, size of titan prosthesis PORP 2.5 mm was chosen. Hearing level increased for 82% out of patients by 10-30 dB after the operation. Titan prosthesis TORP size 4-4.25 mm was chosen for 34 (28.4%) out of 120 cases. Hearing level increased by 10-30 dB for 80% out of patients involved after the operation. Implantation of Titanium prosthesis increased hearing capability by 80% dB. We drum cover the cartilage and cartilage film is used to by Canal wall down, Canal wall updone. Hearing level decrease d by patients involved after the operation. Implantation of Titanium prosthesis increased hearing capability by 80% dB. The air transfer of more than35 dB air-bonegapofmorethan15dB we observed defect of hearing bone
