Description

An ear anti-scar orthosis

technical field

The utility model relates to the technical field of medical equipment, in particular to an ear anti-scar orthosis.

Background technique

The outer ear is an important organ of the human face. With the advancement of medicine and the summary of actual outer ear treatment, a large number of congenital microtia and outer ear burns have occurred in the outer ear.

1: For outer ear burns because the outer ear is exposed and the skin of the ear is thin. When accidents such as burns or scalds occur, it is easy to cause great damage to the ear. For example, deep burns often lead to outer ear defects or scar hyperplasia. Due to the complex structure of the external auricle, it is difficult to cover the external auricle with the traditional application of an elastic mask in the treatment of burns. Therefore, at the present stage, the treatment of scar hyperplasia after middle and outer ear burns is relatively difficult. The general treatment methods are topical drug rubbing and silica gel sheeting. The general treatment of topical drug rubbing is easily affected by the external environment and the treatment effect is not good. , The silicone sheet is easy to fall off and difficult to fix.

2: For congenital microtia, the most commonly used treatment method is ear reconstruction through surgery. Auricle reconstruction surgery is generally divided into stages II-III. The commonly used surgical plan is to take costal cartilage or other implantable materials (Medpor, expanded body) as raw materials, and carve them into scaffolds for reconstructing the auricle. Planar to three-dimensional full auricle reconstruction. This method is widely used, but there are problems such as scar hyperplasia behind the ear after surgery, which leads to smaller ear cranial angle and shallower depth, which eventually leads to long-term fusion and deformation of the implant, which affects the surgical effect of reconstructed auricle. Therefore, congenital ear reconstruction After the operation, the patient needs to wear a long-term external force to prevent the lower cranium and ear feet caused by the contracture of the reconstructed auricle, and then cause the deformed contracture of the reconstructed auricle. At the same time, it is also necessary to frequently apply medicine or use a cover to prevent Reconstruction of the pinna produces scarring.

The external ear that cannot be fully wrapped and covered by the existing treatment methods in the later stage of treatment, such as the burnt outer ear and the post-stage treatment of auricle reconstruction surgery for microtia, have poor therapeutic effects and are prone to scarring.
