About Technique

The Porous Polyethylene Implant Ear Reconstruction

Dr. John Reinisch pioneered the ear reconstruction technique with a porous polyethylene (PPE) implant in 1991. It is now the most advanced surgical treatment for microtia.

The implant is made of a microporous, high-density polyethylene implant designed to reconstruct the outer ear. The framework is biocompatible — meaning the body’s own blood vessels and tissue integrate with the material, promoting natural healing without rejecting it.

Each implant is customized to match the shape and projection of the patient’s opposite ear, aiming for a natural-looking ear and symmetry.

Key Advantages

Setting the Global Standard in Pediatric and Reconstructive Surgery

Single-Session Surgery

Dr. Reinisch typically completes implant ear reconstruction in a single procedure. Traditional rib cartilage methods require at least two separate surgeries. One surgery means less time under anesthesia, less disruption to the family, and faster results.

Earlier Treatment — As Young as Age 3

Rib cartilage reconstruction requires waiting until a child has sufficient cartilage, typically around age 8–10. PPE implant reconstruction can be performed as early as age 3, before children start school and are exposed to peer comments about their appearance. Young children tend to experience little discomfort and stress from the surgery.

No Hospitalization Required

Usually, implant ear reconstruction is performed as an outpatient surgery. Patients typically go home the same day, with recovery focused on comfort and protective care of the surgical site.

Faster Recovery, Less Pain

Because this method does not require harvesting rib cartilage from the patient’s body, there is no donor site, no chest scar, and significantly less post-operative discomfort. Light activities can usually resume within days.

Combined Hearing Restoration

We offer a combined approach in which cosmetic appearance and functional hearing can be addressed at the same time. This can be either a canalplasty (CAM: Combined Atresia Microtia repair), or the placement of a hearing device.
