ABSTRACT
Objective To compare the clinical efficacy of different surgical treatment on cholesteatoma otitis media and analy‐sis its differences .Methods Totally 100 cases of patients with cholesteatoma otitis media in hospital were divided into two groups , 50 cacse in each group ,the control group used open mastoidectomy for treatment ,the experimental group used complete bi‐style mastoidectomy ,and the postoperative clinical efficacy were observed .Results The experimental group patients after radical mas‐toidectomy complete bi‐style treatment ,air conduction hearing threshold (26 .89 ± 7 .23)dBHL and gas bone conduction (12 .54 ± 3 .78)dBHL were significantly lower than after open radical mastoidectomy treatment of patients in the control group (41 .38 ± 10 .56)dBHL and gas bone conduction (22 .57 ± 5 .96)dBHL(P<0 .05);after different surgical treatment ,the cholesteatoma otitis media total efficiency (92 .00% ) of experimental group was significantly higher than control group (64 .00% ) ( P< 0 .05 ) . Conclusion The complete bi‐style mastoidectomy is the treatment of cholesteatoma otitis media ,which can effectively repair dam‐aged eardrum ,restore patient hearing to the maximum extent ,help to restore patient′s disease and improve the quality of life of pa‐tients .
