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. 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. <0.05 was considered statistically significant. In the lower group, the air conduction threshold and air-bone gap at 3 months postoperatively were significantly decreased in comparison with those preoperatively（<0.05），as was the air-bone gap at 6 months postoperatively（<0.05）. In the higher group, the air conduction threshold and air-bone gap were significantly decreased at 3, 6 and 12 months postoperatively（<0.05）. 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.
探讨咽鼓管球囊扩张术后不同程度咽鼓管功能障碍的后天性原发性中耳胆脂瘤听力阈值的变化。本回顾性研究纳入了40例接受开放式乳突根治术+鼓室成形术+咽鼓管球囊扩张术的中耳胆脂瘤合并咽鼓管功能障碍患者。所有患者均于2020年11月至2022年4月入院。术前咽鼓管评分为0 - 2分的定义为较低组，3 - 5分的定义为较高组。于术前及术后1、3、6和12个月进行纯音听力测定。计算250 - 4000Hz骨导阈值和气导阈值的平均值，并同时计算气骨导间距。采用SPSS 25.0进行统计分析。P < 0.05认为差异具有统计学意义。较低组术后3个月气导阈值和气骨导间距较术前显著降低（P < 0.05），术后6个月气骨导间距也显著降低（P < 0.05）。较高组术后3、6和12个月气导阈值和气骨导间距显著降低（P < 0.05）。中耳后天性原发性胆脂瘤合并咽鼓管功能障碍患者经咽鼓管球囊扩张术后气导阈值和气骨导间距显著降低。咽鼓管功能障碍较轻的患者听力改善持续时间更长。
