  1. This table shows that there is no statistically significant difference between the IT Dexa group and the Dexa through grommet group regarding control of vertigo except for the 12 months. At 12 months, all cases of Dexa through grommet showed complete and substantial control, while 30% of the IT Dexa group showed limited control at this time.
