Early activation of active middle ear implants: a prospective study

Vibrant Soundbridge (VSB) is an active middle ear implant that serves as a solution for people unable to use conventional hearing aids properly. Surgical techniques for VSB implantation have progressively advanced, improving its outcomes. Traditionally, VSB processor activation transpires around four weeks after the surgery to provide enough healing; however, contemporary practices in cochlear implant and bone-anchored hearing device activations indicate reduced waiting times. The purpose of this research is to explore the feasibility, safety, and advantages of early VSB activation.

This prospective study was conducted in two phases. In phase one, the patients only attempt using the device on the first business day after surgery and then return in 4 weeks for a complete and standard fitting and device use. In the second phase, participants had a thorough fitting and began using the device on a regular basis the first working day after surgery. Feasibility, safety, and audiological results were assessed throughout both phases.

Early activation was successfully achieved in all patients in the early group without significant complications. When comparing the audiological examination and fitting parameters between the initial session the day after surgery and the one-month follow-up, there was no statistically significant change.

The study emphasizes the possibility for early VSB activation, which might minimize wait times and enhance patient satisfaction without compromising device function. Further study is required to validate these results in broader groups and investigate long-term consequences.
