This was in agreement of Bodmer et al. (34) and Lin et al. (35), who challenge the functional significance of CP values or caloric unresponsiveness in the prediction of long-term vertigo control, while Hone et al. found an absence of ice water response was highly predictive of adequate vertigo control and recommend a total chemical ablation of VOR function by intratympanic gentamicin treatment (36). Here, CP is linked to Vertigo.
