摘要：Objective:The purpose of this study was to evaluate the functional and patient-reported outcomes,and their correlation,after percutaneous bone-anchored hearing aid(BAHA)implantation.Methods:A prospective study was conducted between January 2018 and December 2020 in a tertiary care center.All adult patients who were implanted with a percutaneous BAHA device during this eval-uation period were included in the study.Complete auditory function and patients reported outcome measures(PROMs)were assessed in the preoperative period and 6 months after the implant activation.The PROMs included a generic form(Medical Outcome Study 36 Short Form Healthy Survey(MOS SF-36)),and three disease-specific forms(Hearing Handicap Inventory(HHI),Satisfaction with Amplifica-tion in Daily Life Scale(SADLS),and Tinnitus Handicap Inventory(THI)).Results:Twenty-two patients with an average age of 53 years were included in the study.The overall functional gain with the BAHA in sound-field pure tone average(PTA)was 29 dB,with no statistically significant differences according to surgical indication(F(3,18)= 2.319,p = 0.110).The greater the preoperative air-bone gap,the greater the functional gain obtained(r = 0.505,p＜0.05).In the PROMs,we found a significant improvement in HHI scores(p＜0.005)and a significant increase in overall SADLS scores(p＜0.05)with the use of percutaneous BAHA devices.We did not verify any statistically sig-nificant correlation between functional and PROMs results.Conclusions:The BAHA is a safe and effective alternative hearing rehabilitation option in selected pa-tients.The PROMs results prove patient's overall satisfaction.
