Atresia, Conductive Hearing Loss, Hearing Loss

Brief summary

The purpose of this study is to in a proactive manner collect high quality data from a pediatric patients who have undergone a bone anchored hearing solution, using the Ponto BHX implant, in clinical practice. This to further increase the knowledge of using the system.

Interventions

DEVICEBone Achored Hearing surgery

This is a observational study of pediatric patients undergoing bone anchored hearing surgery. The collected data will be used to assess the implant stability development of the Ponto BHX implant during up tp 24 months after implantation in a pediatric population undergoing bone anchored hearing surgery.

Design outcomes

Primary

MeasureTime frameDescription
Stability 12 months12 months post surgeryThe development of implant stability during the first 12 months after implantation; as measured by difference in mean of (Implant Stability Quotient) ISQ low 12 months compared to surgery.

Secondary

MeasureTime frameDescription
Stability 24 months24 months post surgeryDifference in mean of ISQ low at 24 months compared to surgery
Implant survival rate24 months post surgeryImplant survival rate in percent compared to litterature
Performance audibility PTA41 month post surgeryThe difference between abutment-aided and softband-aided sound field Pure Tone Average of thresholds at frequencies 500, 1000, 2000 and 4000 Hz (PTA 4) in preoperative condition and at fitting.
Performance audibility1 month post surgeryDifference between abutment-aided and softband-aided sound field Pure Tone thresholds at frequencies 500, 1000, 2000, 4000, 6000 and 8000 Hz) in preoperative condition and at fitting
Performance speech intelligibility1 month post surgeryDifference between abutment-aided and softband-aided speech intelligibility in SNR in preoperative condition and at fitting.
Sustainability of audibility PTA4 performance1 month, 12 months, 24 months post surgeyDifference between abutment aided sound field PTA 4 over time
Skin conditions Holger7-10 days,12 months, 24 months post surgerySkin assessment as assessed with maximum Holgers score per patient. Maximum score 4. 0= no adverse skin reaction, 4=maximum adverse skin reaction.
Skin conditions IPS evaluation7-10 days,12 months, 24 months post surgerySkin condition as assessed by (Inflammation, Pain, Skin height/numbness (IPS) score. I scale randing from 0-4, Pain scale ranging from 0-2, Height scale ranging from 0-2. Total score 8, 0=no adverse skin reaction, 8=maximum adverse skin reaction
Sustainability of audibility performance1 month, 12 months, 24 months post surgeyDifference between abutment aided sound field Pure Tone thresholds at frequencies 500, 1000, 2000, 4000, 6000 and 8000 Hz over time
Sustainability of speech intelligibility performance1 month, 12 months, 24 months post surgeyDifference between abutment aided speech intelligibility over time
