Vashishth A, et al. - This trial encompassed the assessment of the long-term surgical outcomes of cochlear implantation (CI) in chronic otitis media (COM) with cholesteatoma and open cavities using subtotal petrosectomy (STP). In addition, authors resolved to appraise the device explantation (DE) patients and reimplantation considerations. Findings illustrated the feasibility of CI in COM with cholesteatoma and open cavities with the use of STP. It was determined that single-stage implantation could be carried out in the absence of purulence. The risk of DE was persistent, regardless of the low risk of residual cholesteatoma post meticulous disease removal, particularly in open cavity patients. It was found to be higher than standard implantation. Herein, reimplantation was often possible with cautious considerations.
