But Atala said: “This is an important advance for the regenerative medicine field. 3D printing aims to provide a number of advantages over handmade engineered tissues, including scale-up, higher design precision and decreased costs.” Wash and dry hands before use. Follow instructions carefully. Improperly fitted earplugs will be ineffective in reducing noise levels. Wearer should ensure that the earplugs are fitted, adjusted and maintained in accordance with the manufacturer’s instructions. Earplugs are worn at all times in noisy surrounding. If recommendations are not adhered to, the protection afforded by the earplugs will be severely impaired.

Wash in warm, soapy water, rinse and allow to dry naturally. Replace the earplug after 1-2 washes or when they no longer return to their original shape and softness. These earplugs are not for use in industrial applications. Always remain aware of your surroundings, especially when outdoors. This product may be adversely affected by certain chemical substances. Further information should be sought from the manufacturer.

Atala said it was not the first time tissue engineered ears, made with the patient’s own cells, had been implanted in humans. An implant made from such cells cultured on a polymer scaffold has previously been reported in China.

Reusable soft foam earplugs effectively reduce harmful, irritating noise and they are comfortable to wear. They are ideal for use when sleeping, working, travelling or swimming. While compressed, insert the earplug well into the ear canal. Fitting the earplug is easier if the outer ear is pulled outward and upward during the insertion. With the fingertip, hold the earplug in place until it begins to expand and fills the ear canal. Over half of the earplug should be inside of the ear canal. Roll the earplug between the thumb and finger, pressing on it until it is compressed into a very thin crease free cylinder.

While long-term follow-up of those receiving the implants is needed, Dr Daniel Cohen, 3DBio’s chief executive, described the real-world application of the technology as “a truly historic moment”. He said he hoped the clinical trial could have potential beyond microtia.
