A woman’s own cells were used to create a 3D-printed ear

A 20-year-old woman has become the first person in the world to receive a 3D-printed human ear implant that uses her own cells.

A medical team from the United States said that they had successfully repaired a human ear using the patient’s own tissue to create a 3D bioimplant, a pioneering procedure that they hope can one day be used to cure others suffering from a rare birth defect.

The procedure was part of a preliminary clinical trial to evaluate the implant’s safety and efficacy in people with microtia, a condition in which the external ear is small and irregularly shaped.

3DBio Therapeutics developed the AuriNovo implant, and Arturo Bonilla, founder and director of the Microtia-Congenital Ear Deformity Institute in San Antonio, Texas, performed the treatment.

In a statement, Bonilla stated, “I am inspired by what this technology might mean for microtia youngsters and their families.” “As a doctor who has seen thousands of youngsters with microtia from all across the country and the world.”

He hopes the implant may one day replace the existing treatment for microtia, which requires grafting cartilage from a patient’s ribs or reconstructing the outer ears with synthetic materials such as porous polyethylene (PPE).

The method entails creating a blueprint by 3D scanning the patient’s opposite ear, then extracting a sample of the patient’s ear cartilage cells and growing them to an appropriate number.

These cells are combined with bio-ink made of collagen and molded into an outer ear. The implant is encased in a printed, biodegradable shell that provides immediate support but eventually dissolves in the patient’s body.

The implanted ear is expected to mature over time, taking on the natural appearance and feel of a normal ear, including flexibility. The clinical research, which is being done in California and Texas, is expected to enroll 11 participants.

Microtia affects around one out of every 2,000-10,000 babies, according to the Centers for Disease Control and Prevention. Two factors that can increase risk are diabetic mothers and a maternal diet low in carbohydrates and folic acid.

Boys are more likely than girls to be afflicted, while Hispanics, Asians, Pacific Islanders, and Native Americans are more affected than non-Hispanic whites.
