To identify whether an increased body mass index (BMI) predisposes patients to more soft tissue problems after placement of a Bone-Anchored Hearing Aid implant.
We retrospectively reviewed 88 adult patients who met criteria for inclusion in the study.
Ten (11.4%) of the 88 patients had significant soft tissue reaction requiring excision, revision of the skin graft, or placement of a longer abutment (8.5 mm). Of these 10 patients, 4 required placement of a longer abutment, whereas 4 underwent revision skin grafting. All 10 patients had scar excisions in the office. Of the 10 patients, 9 were considered obese with a BMI of 30 lb/in or greater. One patient was considered overweight with a BMI of 28.1 lb/in. The mean BMI for those patients with significant soft tissue reactions was 34.2 lb/in. The mean BMI for patients with no reaction or minor reactions was 27.6 and 27 lb/in, respectively. No patient lost an implant due to soft tissue reaction during the follow-up period.
Our study demonstrates that after Bone-Anchored Hearing Aid surgery, most patients (78/88, 88.6%) had no soft tissue reaction or had only a mild reaction that was easily treated. However, there are a definite percentage of patients who may develop significant scarring over time. This study identified a significant relationship between obesity (BMI > 30 lb/in) and extensive soft tissue reaction around the implant site.
确定身体质量指数（BMI）升高是否会使患者在植入骨锚式助听器后更容易出现软组织问题。
我们回顾性分析了符合纳入研究标准的 88 例成年患者。
88 例患者中有 10 例（11.4%）发生明显的软组织反应，需要切除、修改皮瓣或植入更长的接体（8.5 毫米）。这 10 例患者中有 4 例需要植入更长的接体，4 例进行了皮瓣修改。所有 10 例患者均在办公室进行了瘢痕切除术。这 10 例患者中有 9 例被认为肥胖，BMI 为 30 磅/英寸或以上。1 例患者被认为超重，BMI 为 28.1 磅/英寸。有明显软组织反应的患者的平均 BMI 为 34.2 磅/英寸。无反应或反应轻微的患者的平均 BMI 分别为 27.6 和 27 磅/英寸。在随访期间，没有患者因软组织反应而丢失植入物。
我们的研究表明，在植入骨锚式助听器后，大多数患者（88.6%，88/88）没有软组织反应，或仅有轻微反应，易于治疗。然而，确实有一定比例的患者随着时间的推移可能会出现明显的瘢痕。本研究确定了肥胖（BMI>30 磅/英寸）与植入部位周围广泛的软组织反应之间存在显著关系。
