Jang Jung-hoon (former professor of otolaryngology at Ajou University Medical School) said he drew this result from a study conducted jointly with researchers from the Federal Institute of Technology in Lausanne, Switzerland, and the Department of Electronic Engineering at Yeungnam University.
The paper was published in the latest issue of Sensors and Actuators B: Chemical, a prestigious international journal in the field of state-of-the-art chemistry and biosensor research, entitled "Additive manufacturing of flexible, bio-gradable drug implants for sustained release of multiple drugs into the cochlea".
The research team developed a flexible and biodegradable drug implant so that various types of drugs can be continuously released into the cochlear tube over a long period of 30 days or more. After a certain period of time, the drug storage part biodegrades and disappears, so no additional removal surgery is required.
In addition, it is made 50 times more flexible than conventional electrodes, thereby minimizing the physical impact on internal tissues when inserted into the cochlear tube, thereby increasing the stability of surgery.
Otolaryngology academia believes that the results of this paper have the potential to fundamentally change artificial perioperative surgery. The most important change is to minimize the damage to residual hearing that can occur during the surgical process and to significantly improve the patient's hearing preservation ability.
In particular, it is remarkable that multiple drugs can be released simultaneously and precisely. For example, by using drugs that reduce inflammation and drugs that protect the nerves, the therapeutic effect can be maximized, the researchers said. This has increased the possibility of customized treatment that provides the most suitable combination of drugs depending on the patient's condition.
