Meniere's disease: Therapeutic options
2021
Meniere's disease (MD) is characterized by the triad of fluctuating hearing loss, episodic vertigo and tinnitus, and by endolymphatic hydrops found on postmortem examinations. Since the description of endolymphatic hydrops by Hallpike and Cairns, the physiopathology of Meniere's symptoms has been based on assumption that the pathologic lesion was the cause of the symptoms. Schuknecht proposed the theory of membranous rupture causing the mixing up of endolymph and perilymph leading to the occurrence of Meniere's symptoms. Lawrence confirmed this theory with research on experimental animals. In 1995 the AAO-HNS criteria defines "Possible MD (Grade D), Probable MD (Grade C), Definite MD (Grade…
Intratympanale Intervalltherapie des Morbus Meni�re mit Gentamicin unter Erhalt der Kochleafunktion
2003
Patienten und Methode Zwischen 1997 und 2000 haben wir 57 Patienten intratympanal einseitig mit Gentamicininjektionen (jeweils 0,3 ml = 12 mg) therapiert. Eine Therapieserie bestand maximal aus je einer Injektion an Tag 1, 8 und 15. Intratympanal injiziertes Gentamicin akkumuliert langsam (Durchschnitt unseres Krankenguts: 4,6 Tage) im Innenohr. Die Intervalltherapie vermeidet uberhohte Gentamicinkonzentrationen. Sobald Zeichen einer Innenohrreaktion auftreten (Nystagmus, Unsicherheit, Schwindel), hat die Therapie gewirkt und darf keinesfalls weitergefuhrt werden.
Who is at risk for ongoing dizziness and psychological strain after a vestibular disorder?
2009
Patients with vestibular vertigo syndromes often suffer from anxiety and depression, whereas patients with psychiatric disorders often experience subjective unsteadiness, dizziness, or vertigo. Thus, it has been hypothesized that the vestibular system may be interlinked with the emotion processing systems. The aim of the current study was to evaluate this hypothesis by correlating vestibular and psychiatric symptoms with the course of the disease over 1 year. This interdisciplinary, prospective, longitudinal study included a total of 68 patients with acute vestibular vertigo syndromes. Four subgroups of patients with benign paroxysmal positioning vertigo (BPPV, n=19), acute vestibular neuri…
Cell-specific accumulation patterns of gentamicin in the guinea pig cochlea.
2015
Intratympanic gentamicin therapy has become a popular treatment modality for Meniere's disease (MD) through controlled elimination of vertigo spells caused by the balance organ. However, the known ototoxic properties of aminoglycosides lead to cochlear damage. In order to gain more information about cellular preferences for aminoglycoside accumulation within the cochlea, gentamicin was immuno histochemically localized by light microscopy in male guinea pigs 1 and 7 days after intratympanic application (n = 8 ears/incubation time). Differences in the gentamicin-specific cellular storage capacities were quantified by determination of the local immuno staining intensities. Gentamicin was detec…
Decision making for solitary vestibular schwannoma and contralateral Meniere's disease.
2007
The existence of dual inner ear pathology such as unilateral Meniere’s disease (MD) with a contralateral vestibular schwannoma (VS) is very rare, but provides the otologist with a significant management dilemma. In this study, we present 5 cases of unilateral disabling MD with a contralateral VS in the better hearing ear. Conservative management of the VS is mandated unless there are impending complications, with management directed toward controlling the vertigo attributed to MD. If and when the VS requires intervention, or the hearing in that ear deteriorates to unserviceable levels, cochlear implant of the ear affected by MD prior to addressing the VS provides optimal management.
Long-Term Results after Interval Therapy with Intratympanic Gentamicin for Meni??re???s Disease
2004
Objectives The new single-shot and interval treatment for Meniere's disease with gentamicin was designed to avoid cochlear damage during treatment with gentamicin. Methods To date, 90 patients were treated with the single-shot or interval gentamicin therapy. Fifty-seven cases of Meniere's disease were followed up prospectively between 2 and 4 years. During one treatment series, a maximum of three intratympanic gentamicin injections within 15 days were applied, each consisting of 0.3 mL (12 mg) of gentamicin (days 1, 8, and 15). Thirty of these 57 patients (53%) needed only one injection to be controlled (single-shot treatment). Results Vertigo attacks were completely controlled in 95% and p…
Intratympanic gentamicin: a 1-day protocol treatment for unilateral Meniere's disease
2006
Abstract Purpose The objective of this study was to assess the usefulness of low-dose intratympanic gentamicin administration in patients with Meniere's disease (MD). Materials and Methods We carried out a retrospective review of the charts of 55 patients with definite MD in accordance with the AAO-HNS (American Academy of Otolaryngology–Head and Neck Surgery) Diagnostic Scale who were treated at Gruppo Otologico (Piacenza, Rome, Italy). The treatment protocol consisted of 3 intratympanic injections of gentamicin at a 12-hour interval between each administration. Results Results were resumed in accordance with AAO-HNS criteria and showed complete control of vertigo spells in 60% (class A), …
Evolution of migraine vertigo in overlapping syndrome with ménière’s disease: Prognostic role of instrumental examination
2021
Migraine vertigo (MV) and Ménière's disease (MD) share several signs and symptoms such as tinnitus, fullness, photophobia, phonophobia, headache and vertigo spells lasting hours.The aim of the present study was to prospectively observe patients with MV with a sporadic audiological symptom evaluated with clinical examination, Vestibular Evoked Myogenic Potentials (VEMPs), ECochG and v-HIT.The finding of VEMP asymmetry, according to our cut-off of 33% of difference between sides, resulted in 20 cases, of which 6 had asymmetry of both c-VEMPs and o-VEMPS, all with development of fluctuating hearing during follow-up. ECochG was positive for endolymphatic hydrops in 12 patients.The evolution of …
Selective Chemical Vestibulectomy
1997
In an attempt to destroy the peripheral vestibular labyrinth selectively in patients suffering from intractable vertigo as a result of end-stage Meniere’s disease, 25 patients underwent selective chem
