Vestibular neuronitis is a sudden onset of vertigo caused by the involvement of vestibular neurons, and patients usually require 1-2 weeks of treatment to recover. Vestibular neuronitis may present with symptoms of upper respiratory tract infection two weeks before the onset of the disease. The lesion usually occurs in the peripheral part of the vestibular ganglion or vestibular pathway, and the main clinical manifestations of the patient are vertigo and spontaneous nystagmus, accompanied by gastrointestinal symptoms such as nausea and vomiting, without tinnitus or deafness. Usually the vertigo lasts for a short time, but a few patients may have residual dizziness and unstable walking sensation of varying degrees, which may last for several days or months, and the symptoms gradually worsen with activity. If patients have severe vertigo and vomiting they can be given intramuscular injections of promethazine hydrochloride or diazepam, and after the vertigo is reduced they can take diazepam, promethazine or flunarizine, vitamin B1 and B6 to improve their symptoms, and usually after 2 weeks of active treatment patients can gradually recover. In addition, patients with vestibular neuronitis should also pay attention to bed rest to avoid sound and light stimulation, head and neck activities to induce vertigo.
