Vocal Implant System (VOIS) is an adjustable long-term implant to treat glottic insufficiency. The implant is available in four sizes that fit all laryngeal dimensions. VOIS consists of a titanium housing and fixation plate, with a silicone balloon that can be adjusted via the port membrane to give glottic closure.
VOIS’s intra and postoperative adjustment, reduces revision cases and ensures the voice is restored back to prior levels.
