To establish the incidence and correlation between the degree of soft tissue reaction and the body mass index (BMI) according to age and gender after a bone anchored hearing aid (BAHA) implant.
We did a 1-9-year follow-up for the all the patients who underwent surgery in our department with BAHA implant system. Soft tissue reactions were classified in accordance with the Holgers classification on regular patient visits. BMI was calculated for each patient, and changes were recorded at least once a year.
47 patients were evaluated. 58% were operated on for chronic otitis with mixed or conductive hearing loss; 20% had unilateral or bilateral atresia and 16% had single sided deafness (SSD); other indications were otosclerosis and syndromic patients. The grade of Holgers classification significantly correlated at a 0.001 level with BMI (Spearmans rho 0.452). Holgers grade also differed significantly between the sexes-skin reactions in females were less frequent. An ANOVA test did not reveal any statistical difference between patients with dissimilar indications for BAHA.
If performed carefully, BAHA surgery produces a favorable outcome. The Holgers grade may change as time passes. If skin reactions appear, they can be treated through local or systemic therapy, and they may turn into a normal grade. Adipose patients should be treated with special care because they are more prone to soft tissue reactions.
根据年龄和性别，确定骨锚式助听器（BAHA）植入术后软组织反应程度与体重指数（BMI）之间的发生率及相关性。
对在我科接受BAHA植入系统手术的所有患者进行了1至9年的随访。在定期门诊时，根据霍尔格斯分类法对软组织反应进行分类。计算每位患者的BMI，并每年至少记录一次变化情况。
共评估了47例患者。58%的患者因慢性中耳炎伴混合性或传导性听力损失而接受手术；20%的患者有单侧或双侧耳道闭锁，16%的患者为单侧耳聋（SSD）；其他适应症为耳硬化症和综合征患者。霍尔格斯分类等级与BMI在0.001水平上显著相关（斯皮尔曼相关系数为0.452）。霍尔格斯等级在性别之间也存在显著差异——女性的皮肤反应较少见。方差分析未显示BAHA不同适应症患者之间存在任何统计学差异。
如果操作仔细，BAHA手术会产生良好的效果。霍尔格斯等级可能会随时间变化。如果出现皮肤反应，可以通过局部或全身治疗进行处理，且可能转变为正常等级。肥胖患者应特别护理，因为他们更容易出现软组织反应。
