Abstract:
OBJECTIVE:To investigate the influence of drying the ear canal by cleaning the focus of infection in the posterior tympanum in middle ear operations.
METHOD:Retrospectively analyze 168 cases of middle ear operations, which were divided into two groups by whether the posterior tympanum was open or not in the operation process. Then comparing the drying ear rate.
RESULT:The drying ear rate (DEC) were 81.7% (67/82) and 91.9% (79/86) in the posterior tympanum unopened and opened group, respectively. In the posterior tympanum unopened group, the DEC rate were 78.9% (30/38) and 84.1% (37/44) in 38 cases of chronic otitis media and mastoiditis with cholesteatoma and in 44 cases of chronic otitis media and mastoiditis with granulation tissue, respectively. In the posterior tympanum opened group, the DEC rate were 88.2% (37/42) and 94.7% (42/44) in 42 cases of chronic otitis media and mastoiditis with cholesteatoma and in 44 cases of chronic otitis media and mastoiditis with granulation tissue, respectively. In the posterior tympanum unopened group, the DEC rate were 81.7% (36/44) and 84.6% (34/38) in 44 cases of radical mastoidectomy and in 38 cases of tympanoplasty; compared with the posterior tympanum opened group, the DEC rate were 91.3% (42/46) and 92.5% (37/40) correspondingly.
CONCLUSION:In the middle ear operation, open the posterior tympanum in convention can not only have profits to clear the insidious focus of infection, but also have profits to skeletonized to lower facial ridge to the utmost limits and make the drainage of the ear canal easy and smooth. At last, the rate of DEC was raised.
