- Endolymphatic sac decompression (ESD) is indicated in intractable Meniere’s disease patients with serviceable hearing. A 43-year-old man presented with recurrent vertigo and fluctuating right hearing loss that had been intractable to medical treatment. ESD was performed for the purpose of vertigo control with hearing preservation. Positional vertigo with profound hearing loss developed immediate after surgery and positional vertigo was resolved within days. Following paralytic vestibulopathy with positive sign on head thrust test also resolved after 2 weeks, while sensorineural hearing loss was not recovered to preoperative level during 1 year of follow up. Recurrent vertigo attacks were developed again 1 year after the operation. Hearing preservation was not always guaranteed in ESD. Furthermore, chance of hearing loss should be included in informed consent though the procedure is purposed for hearing preservation.

Abstract
PDF
- Benign paroxysmal positional vertigo (BPPV) is the most frequent vestibular disorder. Although it is easily cured with canal repositioning maneuvers for the majority of patients, it can be disabling in rare cases. For these patients, surgical treatments may be proposed. The aim of this article is to discuss their indication in intractable BPPV and review the surgical treatments used, the reported cases in the literature. All the articles from 1972 to 2013 that discussed specific surgical treatments in BPPV were reviewed. Many of them reported cases of operated patients and described original techniques. Some others are studies that discussed the three techniques used: singular neurectomy, posterior semicircular canal occlusion and intratympanic injection of gentamicin. Singular neurectomy and posterior semicircular canal occlusion are the two specific techniques used in intractable BPPV. A very small population of patients requires surgical treatments of BPPV. These procedures are difficult and risk compromising hearing. The intratympanic injection of gentamicin can be useful procedure in BPPV associated with Meniere disease. The surgical treatments of BPPV appear to be limited to exceptional cases. When good examination and appropriate treatment fail to cure patients with intractable BPPV, central positional vertigo should be ruled out before irreversible surgical procedures.

Abstract
PDF
- A 59-year-old male patient presented with sudden onset of vertigo and hearing loss. Labyrinthitis due to lateral semicircular canal fistula caused by cholesteamatous otitis media was suspected from temporal bone computed tomography (CT) and clinical symptoms. The patient was treated with canal wall down mastoidectomy with removal of the cholesteatoma and lateral semicircular canal occlusion. Preoperative gadolinium-enhanced magnetic resonance imaging (MRI) images of the inner ear revealed increased signal in the cochlea as well as vestibule. Correlation of the MRI findings and the inner ear involvement in labyrinthine fistula is discussed.
