New Osia® OSI200 active transcutaneous bone-anchored hearing device: how I do it

Dylan Chew et al. Eur Arch Otorhinolaryngol. 2023 Feb.

Abstract

Introduction: The new Osia® OSI200 implant incorporates a receiver coil and Piezo Power™ Transducer into one monolithic unit. Appropriate planning and surgical approach is needed for suitable positioning of the device.

Method: To optimise the surgical field and provide tension-free wound closure our team have adopted a versatile 'Sheffield-S' post-auricular incision which remains hidden within the hairline.

Conclusion: This incision provides adequate exposure for device placement and bone polishing/recessing. The soft tissue approach has resulted in improved operative efficacy particularly in those patients with irregular cortical bone or where pre-existing osseointegrated implants need to be removed or avoided.

Keywords: Auditory prosthesis; Bone conduction hearing; Mixed hearing loss.
