In this article, the present state of the art with respect to audiovestibular testing for Meniere's disease (MD) is reviewed. There is no gold standard for MD diagnosis, and the classic dictum is that even the "best" tests yield positive results in only two-thirds of patients with MD. Still, we advocate the use and further investigation of advanced(More)
Importance Superior canal dehiscence syndrome (SCDS) is an increasingly recognized cause of hearing loss and vestibular symptoms, but the etiology of this condition remains unknown. Objective To describe 7 cases of SCDS across 3 families. Design, Setting, and Participants This retrospective case series included 7 patients from 3 different families(More)
Canal switch is a complication following canalith repositioning procedure (CRP) for posterior canal benign paroxysmal positional vertigo (BPPV). Instead of being returned to the utricle, the loose otoconia migrate into the superior or horizontal semicircular canal. Patients remain symptomatic, and treatment can be ineffective unless the switch is recognized(More)
Vertigo provoked by head rotation is a classic symptom of rotational vertebrobasilar ischemia (RVBI). Inner ear disease can cause positional vertigo and mimic RVBI. We review the case of a patient with vertigo consistently triggered by leftward head rotation when supine. Computed tomography angiogram and dynamic arteriogram failed to show compression of the(More)
We present the unusual case of a competitive swimmer with cervicogenic dizziness manifesting as vertigo while she was surface swimming. This patient complained of brief and episodic room-spinning vertigo consistently associated with swimming the freestyle stroke and was referred to an otolaryngology clinic for evaluation. She did not have significant(More)
Involvement of the superior semicircular canal (SSC) in benign paroxysmal positional vertigo (BPPV) is rare. SSC BPPV is distinguished from the more common posterior semicircular canal (PSC) variant by the pattern of nystagmus triggered by the Dix-Hallpike position: down-beating torsional nystagmus in SSC BPPV versus up-beating torsional nystagmus in PSC(More)
OBJECTIVE Document the use of transmastoid labyrinthectomy to treat disabling vertigo secondary to a lesion in the internal auditory canal. PATIENT A 69-year-old man with nonserviceable left hearing experienced disabling attacks of vertigo refractory to medical measures. Magnetic resonance imaging revealed a small left intracanalicular lesion with an(More)
PURPOSE To evaluate the incidence of coexistent peripheral vestibular dysfunction and cardiovascular autonomic dysfunction in patients undergoing evaluation for dizziness exacerbated by postural changes. MATERIALS AND METHODS Retrospective case review of 56 sequential patients seen from 2003 to 2006 at a tertiary center for a primary complaint of(More)
OBJECTIVE Document a case of bilateral otosclerosis with coexisting bilateral superior semicircular canal dehiscence syndrome and the treatment of hearing loss in this setting. PATIENT A 33-year-old woman presented with bilateral mixed hearing loss; worse in the left ear. This was gradual in onset, and she denied dizziness. Computerized tomographic scan(More)
Superior semicircular canal dehiscence (SSCD) syndrome has been called the great otologic mimicker because its presentation overlaps with otosclerosis, Meniere's disease, perilymphatic fistula, and patulous eustachian tube. A valuable examination finding that can help distinguish SSCD syndrome from other pathologic conditions is the presence of Hennebert's(More)
