The patient had a little bleeding in his left ear after impact 1 month ago, no obvious hearing loss, no significant improvement after medication in local hospital, hearing loss in the left ear with buzzing tinnitus, no ear pain, no vertigo, headache, nausea, vomiting, impaired consciousness, no ear pus, etc. in the last 1 week, now he came to our hospital for further treatment, and was admitted to our clinic with “left traumatic tympanic membrane perforation He was admitted to our hospital for further treatment, and was admitted as “left traumatic tympanic membrane perforation”, with the intention of further surgery. Since the onset of the disease, the patient had good mental status, good physical condition, normal appetite and food intake, good sleep, no significant change in weight, normal stool and normal urine. The patient was admitted to the hospital with a diagnosis of left-sided traumatic tympanic membrane perforation. I was found in the outpatient clinic. Recently, there are quite a lot of patients from Gaoming, who came to see Dr. Zheng by word of mouth or through the internet. This is a good sign, and the eventual development of medical care requires good doctors with their own brand names. The patient’s perforation was medium sized and the surgery was not too difficult. A minimally invasive endoscopic otolaryngoscopic surgery with local anesthesia for tympanic membrane perforation was done. Intraoperatively, the patient could be seen to have a post-traumatic ectropion of the tympanic epithelium to the residual tympanic membrane, resulting in a perforation of the tympanic membrane that was not self-healing. In this case, if the patient can come in as soon as the injury occurs, most of the ectopic epithelium can be self-healed by returning it to its original position under outpatient otoscopy, so that surgery can be avoided. However, with the development and advancement of minimally invasive technology, the surgery is becoming easier and easier. His surgery was completed in about 30 minutes and was painless. The patient felt well at the postoperative checkup, with no discomfort or complications.
