Otitis media continues to be a common disease in this country. Unlike diseases of the eyes, people tend to be less eager to treat otitis media when they get it. Most people with otitis media have a history of more than one year, and the inflammation has eaten away at the bones inside the ear, so medications don’t work and a bone-scraping type of surgery is warranted. However, it seems that ENT doctors are not very active, this is because the traditional surgery is called “radical surgery”, which is mostly destructive, and in the past, there was a saying that “deafness from otitis media, no surgery, no deafness”, which refers to the fact that in order to have a complete surgical effect, the surgeon will remove the patient’s existing bone. In the past, there was also a saying that “you can’t be deaf without surgery”, meaning that in order to have a thorough surgery, the surgeon removed the patient’s original, partially decayed, but still functioning auditory chain. As a new generation of otologists has grown up, tympanoplasty has gained popularity. However, although tympanoplasty can repair the eardrum, the patient’s hearing is not satisfactory, because the human auditory system design is really too wonderful, in less than 1 cubic centimeter of the human middle ear cavity, involving acoustics, mechanics, electricity, the highest level of learning, here in someone’s body the smallest of the three bones, the two smallest joints, the two smallest muscles, composed of an auditory ossicles chain, which is responsible for converting external sound into the inner ear to perceive the sound. It is responsible for converting external sounds into electrical signals perceived by the inner ear. The auditory ossicle chain is the most frequently damaged part of otitis media, and reconstructing the auditory ossicle chain is much more complicated than replacing the “lens” of a cataract patient with an operation. During my 20 years of clinical growth, I have tried various materials for the ossicles: plastic, Teflon, hydroxyapatite…. I have also tried many times to use healthy bone from other parts of the patient’s body to carve the bone under the operating microscope, but the weight of the carved bone was too heavy, resulting in a hearing effect that was not very satisfactory to me. Now, after generations of domestic and foreign scholars’ persistent efforts and countless failures and improvements, we have finally produced titanium artificial hearing bones. After more than 10 years of clinical verification, compared with the hearing bones made of different materials in the past, the titanium hearing bones are closer to our own original hearing bones, and have shown good histocompatibility, lightweight, corrosion-resistant, plasticizable, very low rejection, and can be examined by magnetic resonance imaging. A variety of advanced features. It brings a good news for patients with various otitis media, tympanic membrane repair, skull base fracture, cholesteatoma after surgery and other patients who have the need of hearing reconstruction.
