Minimally invasive surgery for otitis media is currently the most advanced surgical technique for the treatment of chronic suppurative otitis media and cholesteatoma-type otitis media. This technique has the advantages of no skin preparation and hair shaving before surgery, no incision on the body surface during surgery, no medication change after surgery, high success rate, few complications, and good hearing protection. Although Dr. Zheng has been exploring minimally invasive surgery for otitis media for about ten years, minimally invasive surgery for otitis media is still mysterious and difficult to understand for the majority of ear surgeons and otitis media patients. That is why Dr. Zheng has written the story of myself and every patient who underwent minimally invasive otitis media surgery in the form of a continuous chapter book. One is to leave a treatment file for each patient who has undergone minimally invasive otitis media surgery, so that if any problems arise in the future, Dr. Cheng and the patient can work together to find the cause and solve them. Another purpose is to provide a reference for other patients and medical colleagues to dispel the mystery of minimally invasive otitis media surgery. It is hoped that with Dr. Zheng’s vigorous exploration and promotion, minimally invasive surgery for otitis media can be popularized in most hospitals in China in ten to twenty years’ time, benefiting the majority of otitis media patients. Patient Lin, male, 51 years old. He is from Nanhai, Foshan, Guangdong. He has been suffering from otitis media for 30 years and has never undergone surgery. The patient’s left ear was still inflamed a few weeks before, and after I gave him 1 week of medication in the outpatient clinic, the inflammation in the middle ear was basically under control. He came in for surgery after about 1-2 weeks, which is completely different from the previous view that you have to wait for 3 months or even 6 months after the inflammation of middle ear is controlled. This is mainly the result of Dr. Zheng’s gradual breakthrough of previous experiences and concepts in his own clinical practice, which has achieved very satisfactory results in my own practice of minimally invasive surgery for otitis media, greatly reducing the time and cost of medical procedures for patients. Moreover, there was a foreign report last year in which the author’s results after long-term observation were basically in line with Dr. Zheng’s views. The patient’s surgery was the third minimally invasive surgery for otitis media today, done under local anesthesia. The patient’s tympanic cord nerve and tympanic membrane were somewhat adherent during the surgery, but the surgery was relatively smooth and intact, ensuring that the patient’s sense of taste was not affected after the surgery. Therefore, minimally invasive surgery for otitis media is actually based on the traditional microscope using endoscopic technology to make the surgery more delicate and minimize the damage to the patient’s normal structure while allowing the disease to recover completely. A few days ago, there was a China Brand Doctors Conference in Beijing, which was hosted. A lot of doctors mentioned the Trudeau motto: to cure sometimes, to relieve often, to comfort always (sometimes to cure; often to help; always to comfort). This is the current state of medicine as a whole, but for the treatment of chronic suppurative otitis media, we can now use minimally invasive endoscopic techniques to achieve a cure often, so that more patients can have a completely healthy ear through minimally invasive surgery. The patient’s surgery was done in about 45 minutes, and there was no discomfort or complications at the post-operative checkup.
