For decades, bone conduction hearing devices were defined by a small titanium post that protruded through the skin behind the ear. The abutment was visible, sometimes inconvenient, occasionally associated with skin complications—and yet mechanically, it worked remarkably well....
Clinicians counselling bone conduction implant candidates should weigh acoustic performance trade-offs of transcutaneous designs against the cosmetic and soft-tissue advantages; no single design is superior across all outcome dimensions, so device selection should be individualised.
As the field moves toward magnetic and transcutaneous bone conduction systems driven partly by aesthetics, this analysis challenges whether acoustic performance — the core clinical goal — is being sufficiently prioritised in device innovation.
- 01Legacy percutaneous (skin-penetrating post) designs offer direct coupling and strong acoustic output but carry soft-tissue complication risks.
