Concurrent Cochlear Implantation with Resection of Skull Base @entity2698 following Sudden XXXX in an Only Hearing Ear.

@entity1 @entity5513 @entity2698 @entity5 @entity2319 @entity2267 @entity2459
A 72-year-old @entity1 with a known left @entity5513 , left-sided @entity2319 , and a recently diagnosed right infratemporal fossa (ITF) @entity2698 , presented with @entity2459 in his right ear. Imaging revealed right-sided skull base extension and a large @entity5 component. The @entity1 underwent a frontotemporal crainiotomy with concomitant ITF approach. Complete @entity5 resection was possible, though invasion of the otic capsule was present. Immediately postresection, a cochlear implant (CI) was performed via a transmastoid approach. Full electrode insertion was achieved and confirmed by visualization through the dehiscent middle fossa floor. @entity2267 was then performed with a free fat graft. Postoperative imaging confirmed complete @entity5 resection (Simpson grade I) and adequate CI placement. Follow-up magnetic resonance imaging was performed at 6 and 12 months, and no @entity5 recurrence was seen. Prior to CI activation, the @entity1 was completely deaf bilaterally. At 18-month follow-up, however, excellent hearing was achieved with the right CI (16 of 22 electrodes active), and the @entity1 is now conversational with no obvious deficit. His cognitive function is excellent, corresponding to preoperative status, and he is independent in his activities of daily living. Following adjuvant radiation, our @entity1 remains disease free at 18 months.
