Semontmódszer

Semontmódszer, also known as the Semont maneuver, is a non-invasive medical procedure used to treat posterior canal benign paroxysmal positional vertigo (BPPV). This condition is characterized by brief, intense episodes of dizziness and vertigo that are triggered by changes in head position. BPPV is caused by dislodged otoconia, tiny calcium carbonate crystals, that become loose and float within the semicircular canals of the inner ear.

The Semont maneuver specifically targets the posterior semicircular canal, which is the most commonly affected canal in BPPV. The procedure involves the patient sitting upright, then rapidly moving into a lying position with the affected ear down. They remain in this position for a short period, allowing gravity to help move the dislodged otoconia. Following this, the patient is quickly moved to the opposite side, lying down with the affected ear up. This second position is also held briefly. The maneuvers are designed to guide the otoconia out of the semicircular canal and into the utricle, a part of the inner ear where they are less likely to cause vertigo.

Developed by French neurologist Dr. André Semont, this technique is a variation of the Epley maneuver and is considered effective in repositioning the otoconia. The Semont maneuver is generally well-tolerated and can often be performed by a healthcare professional in an office setting. After the procedure, patients may be advised to avoid sudden head movements for a short duration to prevent the crystals from returning to the canal.
