When it comes to minimally invasive surgery for otitis media, there are not few doctors and hospitals that boast that their otitis media surgery is minimally invasive, and some even describe the traditional microscopic otitis media surgery with incisions as minimally invasive, and give the reason: My surgery is done with a microscope, is that not minimally invasive enough? It sounds quite plausible. But none of these can be considered minimally invasive surgery for otitis media. True minimally invasive surgery for otitis media has no incisions on the body surface. In other words, minimally invasive surgery for otitis media does not find incisions in the front and back of the ear, on the scalp, or on the ear screen. So why does minimally invasive surgery for otitis media not require an incision? The following is a brief explanation of the reasons for this: 1. In terms of surgical tools, the main surgical tool for the latest minimally invasive surgery for otitis media is the otoscope, not the microscope. The development of endoscopy is a prerequisite for the development of minimally invasive surgery in the field of surgery. The reason why the endoscope can complete the surgery without making an incision on the skin of the body is because the endoscope can directly pass through the external ear canal, the natural cavity of the human body, to complete the surgery for otitis media, which avoids making a surgical incision. Of course, minimally invasive surgery for otitis media is not at all traumatic, except that the incision is made 2cm deep from the ear canal, which is very difficult to see even for professional ear surgeons without the aid of inspection tools, and for the average person, you will not be able to find it even with a magnifying glass. 2. The rapid development of biological materials has avoided taking the repair materials such as autologous temporalis fascia, periosteum, and cartilage membrane to avoid wounds. Traditional otitis media surgery requires an incision behind the ear or at the ear screen or scalp due to the need to take autologous tissue to repair the broken eardrum. In contrast, the current minimally invasive surgery for otitis media directly uses artificial biomaterials to repair the eardrum, which are now available in many varieties and are all somewhat more effective than traditional autologous materials. More importantly, it speeds up the surgery and greatly reduces the trauma of the surgery, making otitis media surgery easier and easier. Therefore, a true minimally invasive surgery for otitis media is one in which no incision can be found on the body surface. The reason for the incisionless completion of otitis media surgery is due to the application and popularity of endoscopes and biomaterials.
