The system has been used successfully in the operating theatre and has achieved precise cochleostomies. Use of this tool has shown that precise and consistent results can be achieved efficiently. When drilling a cochleostomy the medial interface of the bone structure of the cochlea is discriminated against the delicate endosteal membrane in real-time such that the device penetrates the bone tissue without penetrating the membrane. As a result, trauma to the hearing organ is reduced, there is greater opportunity to retain residual hearing, sterility is maintained and debris can be removed before insertion of the electrode. These factors are expected to reduce the incidence of complications and are of growing importance as cochleostomies are becoming more common in patients with lower degrees of hearing loss.
This approach to drilling has many applications in surgery.
