[Cause analysis of radical mastoidectomy failure].
OBJECTIVE
To investigate the common reasons for the failure of radical mastoidectomy in order to improve the result of treatment and obtain a dry ear.


METHODS
Twenty-eight cases, who achieved no dry ear after radical mastoidectomy,underwent secondary surgery.


RESULTS
All cases obtained dry ear without vertigo or facial paralysis after operation and postoperative dressing.


CONCLUSIONS
The reasons for the failure of radical mastoidectomy result from the incomplete clearance of lesions, the insufficient ventilation of mastoid cavities, the inappropriate postoperative dressings or the residual foreign bodies in surgical cavity. It is the key points to achieve skeletonization adequately, to eliminate the pathological tissues thoroughly under microscope, and to ensure unobstructed drainage of surgical cavities for preventing secondary surgery.
