Abstract：
Objective:To investigate the changes in hearing threshold of the acquired primary cholesteatoma of the middle ear with different degrees of eustachian tube dysfunction after balloon eustachian tuboplasty. Methods:This retrospective study included forty cases with middle ear cholesteatoma and eustachian tube dysfunction who underwent open mastoidectomy + tympanoplasty + balloon eustachian tuboplasty were enrolled. All patients were admitted from November 2020 to April 2022. The preoperative eustachian tube score of 0-2 were defined as the lower group, and the scores of 3-5 were defined as the higher group. Pure tone audiometry was measured preoperatively and 1, 3, 6 and 12 months postoperatively. The average value of bone conduction threshold and air conduction threshold of 250-4 000 Hz were calculated, and the air-bone gap was calculated simultaneously. SPSS 25.0 was used for statistical analysis. P<0.05 was considered statistically significant. Results:In the lower group, the air conduction threshold and air-bone gap at 3 months postoperatively were significantly decreased in comparison with those preoperatively（P<0.05），as was the air-bone gap at 6 months postoperatively（P<0.05）. In the higher group, the air conduction threshold and air-bone gap were significantly decreased at 3, 6 and 12 months postoperatively（P<0.05）. Conclusion:The air conduction threshold and air-bone gap of patients with the acquired primary cholesteatoma of the middle ear and eustachian tube dysfunction were significantly decreased after eustachian tube balloon dilatation. Hearing improvement lasted longer in patients with slight eustachian tube dysfunction.
目的：探讨咽鼓管功能障碍程度不同的后天原发性中耳胆脂瘤患者行咽鼓管球囊扩张术后的听力变化情况。 方法：回顾性分析2020年11月至2022年4月行开放式乳突切开+鼓室成形+咽鼓管球囊扩张术的后天原发性中耳胆脂瘤伴咽鼓管功能障碍患者40例，术前咽鼓管评分为0～2分者为低分组，3～5分者为高分组。分别于术前、术后1、3、6及12个月测量患者纯音听阈，计算250～4 000 Hz骨导听阈、气导听阈平均值，并计算气骨导差。通过SPSS 25.0进行统计学分析，以P<0.05表示差异有统计学意义。 结果：低分组术后3个月时的气导听阈和气骨导差较术前降低（P<0.05），术后6个月的气骨导差较术前降低（P<0.05）。高分组术后3、6和12个月的气导听阈和气骨导差较术前降低（P<0.05）。 结论：后天原发性中耳胆脂瘤伴咽鼓管功能障碍患者行咽鼓管球囊扩张治疗后，气导听阈和气骨导差较术前明显改善，咽鼓管功能障碍程度较轻的患者听力改善维持时间更持久。.
