Osia Implantation in Patients With Prior Craniotomy for Skull Base Tumors

While the Osia active transcutaneous bone conduction device has been shown to be safe and effective, surgical placement of the device can be problematic in patients with a prior craniotomy for tumors of the posterior fossa. This study reports on strategies and outcomes of Osia implantation in patients with previous lateral skull base surgery.

Surgeons and audiologists managing post-craniotomy patients with conductive or mixed hearing loss should be aware that Osia implantation appears feasible in this population, though individualized surgical planning is critical given altered skull anatomy.

Skull base tumor patients represent a challenging, underserved implant candidacy group, and data on active transcutaneous bone conduction devices in this context fills a meaningful gap in surgical guidance.

1. 01Study evaluated the Osia active transcutaneous bone conduction implant in patients with prior craniotomy for skull base tumors.
2. 02Prior craniotomy alters skull anatomy, creating unique surgical and audiological challenges for implantation.
3. 03Outcomes and complications specific to this high-risk subgroup were assessed.
4. 04Findings could expand bone conduction implant candidacy criteria to include post-craniotomy patients.
