Moreover, anamnestic and clinical data revealed a high incidence of benign positional paroxysmal vertigo in our MC series. Bilateral sensorineural hearing loss was found in seven MC patients (22%) and altered vestibular function test values in other seven subjects (22%). In MC patients we found a rather frequent audiovestibular involvement (34.3%). Patients with a previous history of ear damage due to other well-known agents were excluded from the study. Pure tone audiometry, impedance audiometry, brainstem response audiometry and vestibular function were performed. In order to evaluate the nature and prevalence of audiovestibular disturbances in mixed cryoglobulinaemia (MC), 32 consecutive MC patients were studied by a wide audiological and vestibular examination. This article provides information on the differential diagnosis of peripheral vertigo in BPPV, AVN, However, diag-nosis and treatment of the peripheral vertigo can be difficult without knowledge of BPPV, AVN, and Meniere’s disease. It is traditionally relieved with life-style modification, a low-salt diet, and prescription of diuretics. Meniere’s disease is characterized by episodic vertigo, fluctuating hearing loss, and tinnitus. It is treated with symptomatic therapy with antihistamines, anticholinergic agents, anti-dopaminergic agents, and gamma-aminobutyric acid-enhancing agents that are used for symptoms of acute vertigo. Its key symptom is the acute onset of sustained rotatory vertigo without hearing loss. AVN is the second most common cause of peripheral vertigo. BPPV is treated with several canalith repositioning procedures. BPPV is diagnosed from the characteristic symptoms and by observing the nystagmus such as in the Dix-Hallpike test. It is characterized by brief episodes of mild to intense vertigo, which are triggered by specific changes in the position of the head. BPPV is one of the most common causes of peripheral vertigo. The main causes of peripheral vertigo are benign paroxysmal positional vertigo (BPPV), acute vestibular neuritis (AVN), and Meniere’s disease. Among these types, vertigo is a sensation of movement or motion due to various causes. The doctor holds you in this position for 30 seconds.Dizziness can be classified mainly into 4 types: vertigo, disequilibrium, presyncope, and lightheadedness. When your head is on the table, you are now looking down at the table. The doctor then quickly moves you to the other side of the table, without stopping in the upright position.The doctor holds you in this position for 30 seconds. When your head is on the table, you are looking up at the ceiling. The doctor then lowers you quickly to the side that causes the worst vertigo.The doctor turns your head so that it is halfway between looking straight ahead and looking away from the side that causes the worst vertigo.First, you sit on the exam table with your legs hanging off the edge.When your head is firmly moved into different positions, the crystal debris (canaliths) causing vertigo moves freely and no longer causes symptoms. A single 10- to 15-minute session usually is all that is needed.
The Semont maneuver is done with the help of a doctor or physical therapist. The doctor will then help you to sit back up with your legs hanging off the table on the same side that you were facing.
