A Case of Free-Floating Endolymph Particle Found during Transmastoid Posterior Semicircular Canal Occlusion for Intractable Posterior Canal Benign Paroxysmal Positional Vertigo / 대한이비인후과학회지

Benign paroxysmal positional vertigo (BPPV) is a common inner ear cause of vertigo, most of which can be treated by particle repositioning maneuver (PRM). However, in rare cases, positional vertigo could persist or frequently recur after several PRM. In these intractable cases, surgical treatments including singular neurectomy and semicircular canal occlusion have been used. Posterior semicircular canal occlusion has some advantages over singular neurectomy in hearing preservation and feasible surgical technique. Also free-floating endolymph particles causing intractable BPPV are known to occur in about 20% of the cases during canal occlusion surgery. Nevertheless, to the best of our knowledge, there has not been any report on the identification of those particles in the Korean literature. In this paper, we report a case of free-floating endolymph particle found during transmastoid posterior semicircular canal occlusion for intractable posterior canal BPPV.

Perioperative nursing of 18 patients with refractory paroxysmal positional vertigo treated with posterior semicircular canal occlusion / 现代临床护理

Objective To explore the perioperative nursing of patients with refractory paroxysmal positional vertigo treated with posterior semicircular canal occlusion. Method A retrospective analysis was performed to the experience of nursing 18 patients with refractory paroxysmal positional vertigo treated with posterior semicircular canal occlusion.Results The treatments for 17 cases were effective.Two of them had postoperative vertigo and then cured after further treatments.During one year follow-up,17 of them reported no occurrence of vertigo except only one care reporting paroxysmal positional vertigo. Conclusion Preoperative mental care and postoperative observation of the disease are critical for the enhanced curative effects.
