[Long-term results analysis of mastoidectomy for chronic otitis media].
OBJECTIVE
To study the operative indications of chronic otitis media and their long-term results.


METHODS
One hundred and forty-five cases of mastoidectomy were followed for 5 years between 1995-1998. We discussed the results of recurrence and hearing level of radical mastoidectomy, canal wall up mastoidectomy (CWUM) and canal wall down mastoidectomy with mastoid obliteration (CWDM). Advantages and disadvantages were analyzed by the rate of visiting.


RESULTS
RM is almost invariable in hearing. There is no significant difference between CWDM [improved (10.84+/-4.63) dB HL] and CWUM [improved (10.39+/-3.93) dB HL]. The recurrence rate of RM was 11.63%, CWDM was 12.68%, but the CWUM was 22.58%. Rate of re-visiting of RM is obviously higher that of CWUM and CWDM.


CONCLUSIONS
RM, CWUM and CWDM have all advantages, but the indication must be selected carefully. The effect of CWDM is better than that of RM and CWUM for the long-term results in these cases.
