What is Semont (Liberatory) Manoeuvre?

The Semont liberatory manoeuvre was described by Alain Semont in 1988 as a fast-paced alternative for BPPV, used for cupulolithiasis and when the Epley manoeuvre has failed.

The patient starts seated with the head turned 45° away from the affected side, is rapidly tilted onto the affected side, then swung 180° to the face-down position on the opposite side, and finally brought slowly back to sitting. Each position is held for 1–3 minutes.

Success rates are comparable to the Epley manoeuvre (75–90%). The rapid transitions may be unsuitable for elderly patients or those with cervical problems, and modified versions exist.

Symptoms

Vertigo with head-position changes
Cupulolithiasis symptoms
Failure of the Epley manoeuvre
Positive Dix–Hallpike test
Torsional nystagmus
Brief episodes of dizziness

Risk Factors

Recurrent BPPV
Head trauma
Previous ear surgery
Prolonged bed rest
Vestibular pathology
Elderly population (use with caution)

  • Once BPPV has been diagnosed
