Surgical approaches for superior semicircular canal dehiscence repaira
| Approaches | Advantages | Disadvantages | Surgery Technique Approach Most Suitable for |
|---|---|---|---|
| Middle Cranial Fossa | Direct visualization of dehiscence | More invasive requiring craniotomy and limited temporal lobe retraction | All kinds of SSC repair: canal resurfacing, plugging, capping |
| Transmastoid | Less invasive, standard mastoidectomy approach | No direct visualization of dehiscence | Canal plugging and modified resurfacing (of SSC sidewalls and not directly over dehiscence) |
| Transcanal | Outpatient setting | Less efficacious in long-term | Reinforcement or occlusion of round window |
