      Since I did not find a thread about "canal dehiscence" in the "Research News" section, I created one. For those who are concerned by canal dehiscence and tinnitus, here is an article to make up your mind before surgery.

      Sealing of superior semicircular canal dehiscence is associated with improved balance outcomes postoperatively versus plugging of the canal in middle fossa craniotomy repairs: a case series
      DOI: https://doi.org/10.3171/2019.4.JNS19264

      OBJECTIVE

      The authors compared postoperative symptoms between patients with sealed and those with plugged semicircular canal dehiscence repairs.

      METHODS
      In total, 136 ears from 118 patients who underwent surgical repair for semicircular canal dehiscence were identified via chart review. Data from postoperative MRI scans showing preservation or loss of semicircular canal fluid signal and postoperative reports of autophony, amplification, aural fullness, tinnitus, hyperacusis, hearing loss, vertigo, dizziness, disequilibrium, oscillopsia, and headache were amalgamated and analyzed.

      RESULTS
      Patients with preservation of fluid signal were far less likely to have dizziness postoperatively (p = 0.007, OR 0.158, 95% CI 0.041–0.611). In addition, these patients were more likely to have tinnitus postoperatively (p = 0.028, OR 3.515, 95% CI 1.145–10.787).

      CONCLUSIONS
      The authors found that superior semicircular canal dehiscence patients who undergo sealing without plugging have improved balance outcomes but show more tinnitus postoperatively than patients who undergo plugging.

      Ugh... pick your poison: would you like more tinnitus or less balance?

      I personally have no interest, I relayed this information for the benefit of those who are concerned. Canal dehiscence can be a cause of tinnitus.
