case_images: Audiometry of pre and post operation. In Case 1, no significant change in air-conduction (AC) thresholds between pre and post-surgery. An response was observed in the left side oVEMP, and no significant change was observed after surgery. In Case 2, there was a decrease in AC thresholds on the surgical side, resulting in a 15-25 dB air-bone gap in the low frequency range. An enhanced response was observed in oVEMP on the right side only, and no significant change was observed after surgery.

case_images: The air conduction in pure tone audiometry at lower frequencies increased by 10 dB (Figure 2).
case_images: CT imaging. All reconstructed on the Poschl plane. Case 1: This illustrates slices of the left side, the Poschl and coronal planes. Notably, only the left side exhibited a dehiscence of SPS type. Case 2: Poschl plane demonstrating the presence of dehiscence on both sides. Only the right side was symptomatic.

case_images: Following the procedure, there was a remarkable improvement in symptom scores within 11 days postoperatively, and no worsening was observed up to 1,346 days (3.7 years) postoperatively (Figure 3).

case_images: DHI & VSS score of pre and post operation. Following the RWR surgery, there was an improvement in symptom scores. In case 1, DHI from 36 to 12, with no deterioration observed up to 1,367 days (3.7 years). In case 2, DHI from 28 to 2 in 11 days, with no worsening at 1,346 days (3.7 years). VSS remained similar.

case_images: HRCT showed dehiscence of the superior semicircular canal on both sides in the reconstructions on the Poschl plane (Figure 4).
