| Abstract | The BonebridgeTM (BB, MED-EL Corporation, Innsbruck, Austria) is a bone conduction hearing implant employed for patients with conductive and mixed hearing loss, as well as singlesided deafness. The large size of its implantable transducer (height 8.7 mm and diameter 15.8 mm) in comparison to the limited size of the implantation site (the temporal bone) introduces the risk of interference with critical anatomical structures such as the sigmoid sinus or the middle fossa dura. Currently, to plan a position and orientation for the implant, surgeons inspect 2D image slices from computed tomography (CT) data sets. Due to the complex variation in bone thickness and the limited area in which the device can be implanted, establishing an optimal or safe implant location can be a challenging task for the surgeon. Several methods and software tools have previously been developed to assist surgeons in planning the position of the BB [1-4]. In previous work [2-3], a topographic bone thickness map (TBTM) was developed and tested for the planning of BB implantation procedures. Despite promising efficacy results, the approach was rendered clinically inapplicable due to the time required to perform a plan (30 to 70 minutes) and the technical skills required to create the plan. |
