Abstract：Objective To observe the clinical effect of the tympanoplasty that using self-post-auricular various meso-dermal tissue on mastoid cavity obliteration and ear canal posterior wall renovation to repair posterior canal wall .Methods Fifty-four cases of chronic suppurative otitis media with cholesteatoma otitis media were received open tympanoplasty , 21 pa-tients received multiple posterior ear autologous mesodermal tissue filling and repair of mastoid cavity and the posterior wall of external auditory canal were enrolled as the observation group;33 patients received pedicled Myoperiosteal flap with autoge-nous mastoid bone cortex , temporal fascia and ears filled with repair of mastoid cavity and the posterior wall of external audito -ry canal were enrolled as control group .After surgery, all patients were followed up for 6 months, clinical effect were com-pared between the two groups .Results In the observation group , after operation , the ear canal wall complete epithelization time was (27.3 ±2.3) d, the control group was (33.9 ±3.2) d, there was significant difference between 2 groups ( t =2.009, P <0.05).After 6 months of follow-up, ear canal too wide case was not found in the observation group , 1 cases of tympanic membrane forming an obtuse angle (4.8%), the control group had 23 cases of ear canal too wide (69.7%), for-ming an obtuse angle of tympanic membrane in 13 cases (39.4%), there was significant difference between 2 groups (χ2 =21.74,χ2 =6.31, P <0.05).0.5,1.0,2.0 kHz pure tone air conduction threshold in the observation group were increased in 17 cases (80.9%), the control group were increased in 13 cases (39.4%), there was significant difference between 2 groups (χ2 =7.37, P <0.05).Observation group occurred complication in 1 cases (4.8%), the control group occurred in 12 cases (36.4%), there was significant difference between the 2 groups (χ2 =5.39, P <0.05).Conclusion Variety of posterior ear autologous mesodermal tissue repair of mastoid cavity and the ear canal wall , postoperative ear size and function is more close to the normal healthy physiological condition than the conventional method , it has positive significance on the re-covery of physiological structure and function of the ear canal .
