Abstract
GUTIERREZ-FARFAN, Ileana et al. Equations to establish a regression between current units with respect to patient`s age and the use time of cochlear implants. Cir. cir. [online]. 2020, vol.88, n.2, pp.154-162. Epub Nov 15, 2021. ISSN 2444-054X. https://doi.org/10.24875/ciru.19001021.
Objective:
Propose a system of multivariate multiple regression equations in order to establish a mathematical association that allows estimating the current units needed during the adjustment phase with respect to age and time that were used the implants.
Method:
Descriptive cross-sectional study. A total of 41 pediatric patients with a unilateral cochlear implant participated. Three groups were formed and multivariable multiple regression equations were constructed.
Results:
For Group 1, in electrode Groups 3 and 4, there is a lower standard deviation and a similar index of asymmetry of the current units; in Group 2, the groups of electrodes with similar index of asymmetry were 2 and 4, while group of electrodes 3 presented average of 21.54 and dispersion smaller (16.25); in Group 3, groups of electrodes 3 and 4 presented similar standard deviation and average and smaller standard deviation. With respect to the standard estimation error, the lowest variability of current units was obtained in Group 2 for electrode Group 3.
Conclusion:
The proposed equations could be used in the clinical area by knowing the units current needed with respect to age and time of use the implant.
