Abstract
BackgroundThe Cochlear™ Osia® System leaves a retroauricular bump that can cause discomfort and poor aesthetic outcome.MethodTo reduce the retroauricular bump, we introduced an implant well in the bone behind the ear for the transducer. We used cutting and diamond drills to create the implant well with an average depth of 4–5 mm. The surgical time including the implant well (40 min) was within the range of reported average surgical time (52 min).ConclusionIntroduction of an implant well resulted in a better aesthetic outcome and improved patients’ comfort. The reduced distance between BI300 and ear canal might improve audiological outcome.

The CochlearTM Osia® System (Osia; Cochlear, Sydney, Australia) is a new generation of an active transcutaneous bone-anchored hearing implant with a newly developed piezoelectric transducer that is fixed to a titanium implant (BI300)
The implant is indicated in patients with unilateral and bilateral conductive or mixed hearing loss and singlesided deafness
Summary
The CochlearTM Osia® System (Osia; Cochlear, Sydney, Australia) is a new generation of an active transcutaneous bone-anchored hearing implant with a newly developed piezoelectric transducer that is fixed to a titanium implant (BI300). The integrated digital piezoelectric stimulation allows for bone conduction hearing loss of up to 55 dB [1]. We were confronted with the following complaints of the patients: First, patients were unsatisfied with the aesthetic outcome due to the consequent. To reduce these complaints, we needed a surgical method to implant the OSI that led to a smaller or absent bump behind the patient’s ear.
