A vestibular neuronitis can trigger a self-decaying vertigo, which is probably due to an inflammation of the Vestibularisasts VIII. Cranial nerve. After that, the balance function can remain bother to some degree.
Although the etiology is unclear, a viral infection is suspected as the cause.
A vestibular neuronitis can trigger a self-decaying vertigo, which is probably due to an inflammation of the Vestibularisasts VIII. Cranial nerve. After that, the balance function can remain bother to some degree. Although the etiology is unclear, a viral infection is suspected as the cause. Symptoms and complaints as symptoms of vestibular neuritis occur an isolated, strong vertigo with nausea and vomiting and a nystagmus that lasts 7-10 days. It is a unidirectional, horizontal Spontaneous the affected side with schnellschlägigen oscillations in direction of the non-diseased ear. Characteristic of a vestibular neuronitis is the lack of accompanying tinnitus or hearing loss and helps to distinguish them from Meniere’s disease or inner ear inflammation. After the first episode, the condition improved gradually after days or weeks. That some patients still felt remnants of the imbalance (v. A. With rapid head movements), is probably a chronic vestibular. Diagnostic Audiology, electronystagmography and MRI patients with suspected vestibular neuritis are examined audiological and elektronystagmographisch (with caloric stimulation test). To the differential diagnosis to exclude a cerebellopontine angle tumor, brain stem hemorrhage or cerebral infarction, the focus in the gadolinium-enhanced MRI is particularly directed to the inner Gehörkanälchen. A stronger drawing of Vestibularisnerven in MRI is consistent with an inflammatory neuritis. Therapy symptom relief with anti-emetics, antihistamines or benzodiazepines The symptoms of vestibular neuritis are treated symptomatically at short notice as the Meniere’s disease, d. H. with anticholinergics, antiemetics (z. B. prochlorperazine or promethazine, every 6-8 h 25 mg rectally, or 10 mg p.o.), antihistamines or benzodiazepines, and a corticosteroid pulse therapy. After persistent vomiting an infusion of fluid and electrolyte replacement may be necessary. From a long-term use (d. H. For several weeks) vestibular suppressants are not recommended as these drugs delay the vestibular compensation, especially in the elderly. Measures for rehabilitation of balance perception (usually by physical therapists) help to compensate for residual vestibular deficits. Summary Patients show days to weeks severe, permanent vertigo with nausea and vomiting, and nystagmus to the affected side. Hearing loss or tinnitus are not present. The investigations serve to rule out other conditions. Treatment is aimed at the symptoms and includes antiemetics and antihistamines or benzodiazepines; Corticosteroids may also be helpful.
