Description

human ear prosthesis

technical field

The utility model relates to the fields of medical rehabilitation and medical cosmetology, in particular to a human ear prosthesis.

Background technique

Due to congenital deformities, trauma, tumors and other reasons, patients with incomplete or missing human auricles, accompanied by varying degrees of deafness, can adopt methods such as reconstructing auricles and installing prosthetic ears to solve their aesthetic problems; in order to solve their deafness problems, Can be used to wear hearing aids. At present, for patients in this situation, the above two methods can only be adopted at the same time, namely: first perform ear reconstruction or install prosthetic prostheses, and then choose air conduction hearing aids or bone conduction hearing aids according to the different conditions of the patients. Generally speaking, for deaf patients who are unwilling to undergo ear implant surgery and whose external auditory canal is unobstructed, they can choose to install the artificial ear prosthesis by pasting, and then wear an air conduction hearing aid; Deaf patients without auricles, congenital malformations in the middle ear, suppurative otitis media, etc., who are not suitable for wearing air conduction hearing aids, undergo auricle reconstruction or ear implantation after implantation, followed by bone anchor implantation. In the operation, a special electric drill is used to make a bone hole on the cranium where the mastoid behind the ear and the skin is relatively thin, and a 3 to 4 mm long titanium implant is installed. The titanium abutment is screwed into the internal thread of the titanium implant. Bone conduction hearing aids can only be worn after the titanium implant is kept free of weight for at least three months after surgery so that it can fully fuse with the surrounding bone.

For patients, whether wearing air conduction hearing aids or bone conduction hearing aids, it is cumbersome and lacks comfort. Especially for bone conduction hearing aids, patients must endure at least two surgical pains, not only physical and mental torture, but also burdens. Doubled surgical risk.
