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 Zeng, male, 60 years old, from Nanhai, Foshan, Guangdong. He was a patient I saw in the outpatient clinic and came to the hospital on time after making an appointment for surgery in the outpatient clinic. He was diagnosed with chronic suppurative otitis media on the left side, and the surgery was done under local anesthesia. The patient originally asked for general anesthesia, but at my suggestion, he was given local anesthesia instead. The main reason is that local anesthesia is safer and less painful than general anesthesia. The surgery went smoothly. Although the patient’s outer ear canal bone wall was protruding and somewhat obscuring the stump of the eardrum, Dr. Cheng was very experienced as he had done many such surgeries. What may be difficult in others is not even surprising in my case. What was even more amazing was that the patient fell asleep soon after I administered the local anesthetic, and I heard him snoring while I was doing the surgery, and my assistant Dr. Cao said: It seems that your local anesthetic level is very high, and you have achieved the effect of general anesthesia. 40 minutes finished the surgery, and when I woke up the patient, the patient said that the surgery was not painful at all. At the post-operative checkup, the patient was very refreshed and no complications appeared. Judging from this patient’s performance, Dr. Zheng’s current minimally invasive surgery technique for otitis media with local anesthesia is very mature and can achieve painless surgery.
