Therapeutic efficacy of the Galletti–Contrino manoeuvre for benign paroxysmal positional vertigo of vertical semicircular canals in overweight subjects

Abstract

Objective

To compare the Galletti–Contrino manoeuvre with the more widely used Semont–Toupet in overweight subjects presenting with benign paroxysmal positional vertigo (BPBV) of vertical semicircular canals (posterior and anterior canals).

Study design

Prospective cohort study.

Patients

204 patients (BMI range 25–30) with a diagnosis of BPPV of vertical semicircular canals were randomly divided in two groups treated with two different maneuvers: Galletti–Contrino (Group A) and Semont–Toupet manoeuvre (Group B). The results were compared with those obtained from a control group (204 non-overweight subjects with BPV of vertical semicircular canals.)

Intervention

Galletti Contrino/ Semont Toupet manoeuvres.

Main outcome measure(s)

Liberatory nystagmus or vertigo after maximum 2 maneuvers. Vertigo and dizziness intensity scores (Visual analogue scale VAS 0–10) from day 0 to day 5 following the repositioning manoeuvre were also recorded in responsive patients.

Results

While in non-overweight subjects no significant difference comparing the effectiveness of the two manoeuvres was found, liberatory nystagmus and vertigo were more frequently observed after Galletti Contrino manoeuvre in overweight subjects; this difference was statistically significant when posterior canals were involved (P < 0.03). Vertigo and dizziness VAS scores reduced significantly from day 0 to day 5 after therapy in all groups. A more significant reduction of dizziness VAS was recorded in patients undergoing Galletti–Contrino manoeuvre at days 4–5 (P < 0.005).

Conclusion

Galletti–Contrino manoeuvre seems to be significantly more effective than Semont–Toupet manoeuvre in the treatment of BPPV of posterior semicircular canal and may be preferential in patients with limited body movements.
