Efecto de la secuencia de irrigación en los resultados de la paresia canalicular en la prueba calórica bitérmica

Objective: Bithermal caloric tests are among those most commonly used in vestibular function studies and require a properly systematized approach. Irrigation sequence varies between laboratories. Our objective is to study the effect of irrigation sequence on the percentage of vestibular paresis. Material and method: We analysed 1214 records, 77.51 % cold to hot sequences (C-H) and the rest hot to cold (H-C). We considered results above 24 % of vestibular asymmetry to be pathological. Results: In general, 33.36 % of the records were pathological. Groups compared showed that H-C sequence had more significant ( P< .001) pathological results than C-H (46.52 % vs 29.54 %). Conclusion: Irrigation sequence has a significant influence on the outcome of caloric tests to for the detection of vestibular paresis. More studies are needed to confirm the best irrigation sequence.
