【摘要】 目的　探讨治疗粘连性中耳炎的手术适应证及手术方法。方法　对 6 9例 (6 9耳 )粘连性中耳炎患者进行了手术治疗。术后能够随访 1年以上的 4 1例。术前平均 ( x±s,以下同 )骨气导差(2 5 0、5 0 0、10 0 0、2 0 0 0Hz ,4 3 8± 3 9)dB。术中切除粘连的鼓膜以及瘢痕组织 ,进行听骨链重建 ,并用耳屏软骨修补鼓膜穿孔。结果　术后 1个月平均骨气导差为 (2 3 7± 8 6 )dB。 4 1耳术后 1年平均骨气导差为 (2 7 9± 10 7)dB。长期随访组中共有 18耳 (43 9% )术后骨气导差 <2 0dB。有 2 6耳术后听力提高 >15dB。耳显微镜观察鼓膜及中耳 ,术后 2 4耳 (5 8 5 % )的鼓室接近正常。结论　粘连性中耳炎可以进行手术治疗 ,但必须仔细选择手术适应证。用软骨重建鼓膜是治疗粘连的好方法。更多还原

【Abstract】 Objective To study the operative indications and treatment for adhesive otitis media(AOM). Methods Sixty-nine cases of AOM were undergone tympanoplasty between 1995 to 2000. Preoperative average air-bone gap(A-B gap) were (43.7±3.9)dB. Forty-one cases could be postoperative followed up for more than one year. Preoperative average A-B gap of this group were (43.8±4.2)dB.The adhesive ear drum and the other processes in middle ear were inserted and reconstructed with cartilage. Results The postoperative average A-B gap after one month(69 cases) and one year(41 cases) were (23.7±8.6)dB and (27.9±10.7)dB. In the long-time follow-up group,the A-B gap of 18 cases(43.9%)were less than 20 dB. Twenty-four cases(58.5%) become a nearly normal tympanum. Conclusion The AOM can treatment with tympnoplasty. But the indication must be carefully selected.The cartilage was a good material for reconstruction of the ear drum to treatment the AOM. The influence factor were analyzed.更多还原
