Through analysis of the tympanic membrane perforation rate and hearing improvement rate with chronic suppurative otitis media (CSOM) by myringoplasty,to observe the effect of different preoperative conditions such as middle ear lesion,eustachian tube (ET) function and infection status on the postoperative curative effect.Retrospective analysis of EENT Hospital of Fudan University from January 2012 to November 2016 during the 203 cases (203 ears) with clinical data of myringoplasty: according to intraoperative exploration of the presence of purulent secretions in the tympanic cavity,divided into infection active group and infection quiescence group; according to the preoperative results of the function of ET with acoustic impedance test divided into dysfunction or good group; according to the preoperative temporal bone HRCT suggested that the middle ear (mastoid cells,tympanic antrum and tympanic cavity) with or without soft tissue density,divided into the group with no focal lesion and the group with focal lesion. Review endoscopy and pure tone audiometry after 3 to 6 months. Using SPSS 19.0 statistical software to compare the differences among them of tympanic membrane perforation rate and hearing improvement rate.Single factor analysis: ①The infection quiescence group of tympanic membrane perforation rate was 11.93%(13/109),higher than the infection active group [8.51%(8/94)]; the infection quiescence group of hearing improvement rate was 75.23%(82/109),below the infection active group [79.79%(75/94)],no statistically significant differences of them (>0.05).②The group with dysfunction of ET of tympanic membrane perforation rate was 14.06%(9/64),significantly higher than the group[4.04%(4/99)]with good function ET,with statistical difference of them (<0.05); the group with dysfunction of ET of hearing improvement rate was 76.56% (49/64),lower than the group[81.82%(81/99)]with good function of ET,no significant difference of them (>0.05).③The group with no obvious lesion of tympanic membrane perforation rate was 9.09% (10/110),lower than the group [11.83%(11/93)]with focal lesion; the group with no obvious lesion of hearing improvement rate was 78.18% (86/110),higher than the group with focal lesion [76.34%(71/93)],no significant difference of them (>0.05).Multivariate analysis: ①There was a significant correlation of postop-erative tympanic membrane perforation rate with preoperative ET functi-on (<0.05).There was no significant correlation of the postoperative tympanic membrane perforation rate with the infection status and the temporal bone HRCT images in the middle ear lesions (>0.05).②There was no significant correlation of the postoperative hearing improvement rate with the infection status,the ET function and the temporal bone HRCT images in the middle ear lesions (>0.05).Dysfunction of ET and localized lesions of the ear were more common in infection active;the accumulation of purulent exudate on the surface of the tympanic mucosa and localized lesions of the middle ear did not affect the healing rate of the tympanic membrane and the hearing improvement rate; ET function is one of the most important factors that affect the healing rate of tympanic membrane after operation,the patients with ET dysfunction are more likely to affect tympanic membrane perforation,but does not affect the hearing improvement rate.
