Surgical treatment of tympanic membrane perforation is the main treatment modality. A traditional tympanic membrane repair can be performed under a microscope. The materials used for repair are mainly temporalis fascia, mastoid membrane and auricular cartilage membrane. With the development and maturation of endoscopic technology, another alternative repair option is to perform tympanic membrane repair by endoscopically selecting the cartilage and cartilage of the ear screen or the auricle. The endoscopic procedure is minimally invasive and does not require high surgical conditions such as the middle ear dry ear. The incision is a small, hidden incision with a quick recovery. There is no need for large incisions around the auricle and temporal incisions. It is more suitable for some lesbians who are worried about the cosmetic effects of the surgical scar or do not want to cut their hair before the surgery. The operation can be performed under general anesthesia or local anesthesia. The operation time is short and the recovery after the operation is fast. Therefore, there is no need to worry excessively about the trauma and riskiness of the surgery. By repairing the tympanic membrane intact and closing the middle ear cavity, the normal anatomy of the middle and inner ear is returned and its function is restored, eliminating the possibility and worry of complications and improving the quality of life at the same time. The effect is once and for all.
