[The application value of suppression head impulse paradigm in vestibular neuritis]

Objective:To study the parameters of the suppression head impulse paradigm of vestibular neuritis and explore the application value of suppression head impulse paradigm in vestibular neuritis.Method:Twenty patients with vestibular neuritis in our outpatient clinic were selected. The HIMP and SHIMP gain of unilateral vestibular neuritis patients were detected by video pulse detector.Result:All patients with HIMP examination in the affected side can elicit compensatory saccade, the healthy side with no compensatory saccade; SHIMP examination in the healthy side can elicit anti-compensatory saccade, the affected side without compensatory saccade or weak saccades. The HIMP gain of affected side and healthy side of patients with vestibular neuritis were 0.56±0.15 and 0.99±0.13 respectively, and the SHIMP gain of affected side and healthy side of patients with vestibular neuritis were 0.45±0.13 and 0.9±0.13 respectively. The gain of the affected side and the healthy side of HIMP was larger than those of SHIMP, and the difference was statistically significant (P<0.05).The differences of HIMP and SHIMP gain between the affected side and the healthy side were statistically significant (P<0.01).Conclusion:Video head impulse test combined with suppression head impulse paradigm can evaluate vestibular function injury and residual retention in vestibular neuritis, and can also dynamically monitor vestibular compensation in patients.
