Abstract：Objective To introduce the experience of the intact canal wall tympanoplasty in chronic suppurative otitis media. Methods Clinical data of 96 cases of the intact canal wall tympanoplasty for treating chronic suppurative otitis media was retrospectively reviewed. During the operation, the outside wall of attic should be keeped intact, lesions should be re-moved, mucosa should be protected, and the air drainage system of eustachian tube、middle ear、sinus and mastoid shoulded be established. Results The preoperative pure tone audiometry (the average hearing threshold at 0.5,1.0,2.0,4.0 kHz HL) of the mean air bone gap was 0- 10dB in 0 ears(0%)、11-20 dB in 4 ears(4.17%)、21- 30 dB is 29 ears(30.2%),31-40 dB is46 ears(47.9%)、over 40 dB in 17 ears(17.7%).The postoperative pure tone audiometry (the average hearing threshold at 0.5,1.0, 2.0,4.0 kHz HL) of the mean air bone gap was 0- 10dB in 22 ears(22.9%)、11-20 dB in 41 ears(42.7%)、21- 30 dB is 24 ears(25%),over 30 dB in 9 ears(9.3%).Temporal bone CT showed:the proportion of the ear drums mastoid antrum regasifica-tion is 78.1%,and the ear drums mastoid antrum tissue pack is 29.1%. Conclusion The curative effect of the intact canal wall tympanoplasty in patients with chronic suppurative otitis media is satisfactory. The key of the operation is setting up reason-able middle ear ventilation drainage system following the principle of individualization.
