In all groups, multiple treatment sessions were required to achieve a cure. Overall treatment success rate was The difference was not statistically significant. The conclusions were puzzling as most were not backed by the statistical data. The authors stated that BPPV in MD differs from that of idiopathic BPPV in the sense a duration of symptoms is longer, b posterior canal is more frequently involved, c caloric canal paresis is more frequent, d treatment outcome is poorer and e recurrence rate is higher.
Next, the patient is quickly laid down backward with the head just over the edge of the examining table. A positive response confirms the diagnosis of BPPV. Even without treatment, the usual course of the illness is lessening of symptoms over a period of days to weeks, and sometimes there is spontaneous resolution of the condition. BPPV with the most common variant crystals in the posterior SCC can be treated successfully — with no tests, pills, surgery or special equipment — by using the Epley maneuver.
This simple, effective approach to addressing BPPV involves sequentially turning the head in a way that helps remove the crystals and help them float out of the semicircular canal. Several repositioning maneuvers performed in the same visit may be necessary.
The Epley maneuver and other bedside physical therapy maneuvers and exercise programs can help reposition the crystals from the semicircular canals. Recurrences can occur, and repeat repositioning treatments are often necessary. After Epley maneuver treatment, the patient may begin walking with caution. He or she should avoid putting the head back, or bending far forward for example, to tie shoes for the remainder of the day.
Sleeping on the side of the affected ear should be avoided for several days. If the crystals are in a location other than the posterior semicircular canal, slightly different maneuvers may be used, but they are based on the same principle of moving the stones out of the offending semicircular canal. BPPV of the anterior canal is exceedingly rare, since debris in this canal located at the top of the inner ear easily falls out on its own.
Usually no medications are required for BPPV unless the patient has severe nausea or vomiting. If extreme nausea is present, the doctor may prescribe or administer anti-nausea medications, especially if the person would not be able to tolerate repositioning maneuvers otherwise.
