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 Mo, female, 23 years old. She was a patient admitted to my outpatient clinic before New Year’s. She was probably busy because she contacted me through the website a few days ago to be admitted to the hospital, so she was admitted yesterday. The patient’s tympanic membrane perforation was not large and the surgery was not difficult. Since my assistant had gone home for the past few days, the doctor who arranged for me was unaware of the situation and scheduled for general anesthesia surgery, as most of the doctors in our department are still doing more otitis media surgery with general anesthesia. I came to the department early this morning, checked and advised her to do local anesthesia surgery instead, and the patient followed my advice. Thus, all four minimally invasive otitis media surgeries today were local anesthesia surgeries. She had the first one done under local anesthesia. The patient felt no pain during the whole procedure and was very quiet, and the procedure lasted about 35 minutes. I hope this year’s minimally invasive surgery for otitis media in Zheng Ligang can help more patients. The patient felt very well during the afternoon check-up after the surgery, with no discomfort or complications occurring.
