| Popis: | Background: Although several researchers have tried various kinds of canalith repositioning procedures for lateral canalolithiasis, a standard treatment has not been established. We have adopted 90° rotation, which is anatomically appropriate. Objective: To clarify the efficacy of the affected-ear-up 90° maneuver. Materials and methods: The subjects were 23 consecutive patients (15 females, 8 males) who revealed transient direction-changing geotropic positional nystagmus. After determining the affected side, we immediately performed the canalith repositioning procedure. To perform this maneuver: (1) Place the patient in the supine position. (2) Rotate the head toward the healthy side until 90° from the supine. (3) Sit up. (4) Ask the patient to remain upright with the chin down until going to bed. Results: Nineteen patients (83%) became symptom-free by only one maneuver. However, three patients converted to ipsilateral cupulolithiasis of the lateral canal, and one patient required a second maneuver. Conclusion: The affected-ear-up 90° maneuver is effective against lateral canalolithiasis. |
