Further study details as provided by Mayo Clinic:

Primary Outcome Measures:
  • objective improvement [ Time Frame: baseline to 3 months ] [ Designated as safety issue: Yes ]
    The primary outcome measure will be the subsequent (3 month) FGA scores between the control group and the surgery group to assess any objective improvement attributable to surgery


Secondary Outcome Measures:
  • ABC Scale [ Time Frame: baseline to 3 months ] [ Designated as safety issue: No ]
    Secondary objective outcome measures will be changes in conductive hearing loss and changes in cervical VEMP thresholds between the two groups at the 3-month interval. Secondary subjective outcome measures will be ABC Scale and VAS scores between the two groups at 3 months.

  • VAS scores [ Time Frame: baseline to 3 months ] [ Designated as safety issue: No ]
    Secondary objective outcome measures will be changes in conductive hearing loss and changes in cervical VEMP thresholds between the two groups at the 3-month interval. Secondary subjective outcome measures will be ABC Scale and VAS scores between the two groups at 3 months.

Arms Assigned Interventions
Active Comparator: Surgical Group
patients will undergo a primary transmastoid and tegmen mini-craniotomy cartilage cap occlusion surgery.
Procedure: cartilage cap occlusion surgery
placement of a cartilage cap over the dome of the superior semicircular canal through a combined transmastoid and tegmen mini- craniotomy approach.
No Intervention: Non Surgical Group
patients meet the same criteria but will elect not to undergo surgery

Detailed Description:

One option for managing a dehiscent superior semicircular canal is surgical intervention. One of the surgical techniques is the transmastoid and tegmen mini-craniotomy cartilage cap occlusion of the dehiscent superior semicircular canal.
