To study the operative indications of chronic otitis media and their long-term results.
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.
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.
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.
研究慢性中耳炎的手术适应证及其长期效果。
对1995年至1998年间145例行乳突切除术的患者进行了5年的随访。我们讨论了根治性乳突切除术、上鼓室乳突切除术（CWUM）和下鼓室乳突切除术加乳突腔填塞术（CWDM）的复发结果和听力水平。通过复诊率分析优缺点。
根治性乳突切除术听力几乎无变化。CWDM[听力改善（10.84±4.63）dB HL]与CWUM[听力改善（10.39±3.93）dB HL]之间无显著差异。根治性乳突切除术的复发率为11.63%，CWDM为12.68%，而CWUM为22.58%。根治性乳突切除术的复诊率明显高于CWUM和CWDM。
根治性乳突切除术、CWUM和CWDM均有优点，但必须仔细选择适应证。在这些病例中，从长期效果来看，CWDM的效果优于根治性乳突切除术和CWUM。
