Investigating Hearing With Ponto 3 SuperPower, a Bone Anchored Hearing Aid - Investigating Hear

Unmasked and if available masked BC thresholds from audiogram obtained prior to Ponto 3 SuperPower were fitted.

BC In-situ thresholds will be collected from the BC In-situ audiogram obtained when Ponto 3 SuperPower were fitted

Sound field thresholds for frequencies 500Hz, 1kHz, 2 kHz, 3kHz and 4kHz will be collected from sound field audiogram obtained as follow-up after Ponto 3 SuperPower fitting, typically this is collected 3 months post fitting, alternatively from the fitting visit. Thresholds will be obtained aided, and when available unaided

"Speech intelligibility is measured in a sound treated room using sentence tests. The sentence tests used at Norwich and Norfolk hospital is the BKB (Bamford-Kowal-Bench) and/or the The AB\[s\] Isophonemic Monosyllabic Word test (7).~The sentence tests are measured in quiet and/or with background speech-weighted noise."

Classification of skin reactions around skin penetrating implants will be made using the Holgers score. The Holgers classification is a scale from 0 to 4 that is used to grade skin reactions

The Glasgow Benefit Inventory (GBI) contains 18 health status questions, which ask specific questions about how the health problem, in this study hearing loss, has affected their quality of life at the time the GBI is completed. In this study GBI has been collected on patients before intervention and 3 months after fitting of Ponto 3 SuperPower on abutment.

Average power-on usage hours from Ponto 3 SuperPower will be collected.
