A perforated tympanic membrane is, as the name implies, a broken eardrum. While some people do not take tympanic membrane perforations seriously, they do cause a decrease in quality of life. First, because of a perforated eardrum, you cannot swim, wash your hair or bathe in water, which causes a lot of inconvenience. Once infected, it is unsightly to have wetness in the ear or pus and eczema in the outer ear. If the pus flows repeatedly for a long time, sarcoma or even cholesteatoma will grow inside the tympanic chamber, which will be more difficult to cure. Second, tympanic membrane perforation causes hearing loss. The larger the perforation, the more pronounced the hearing loss, and the more episodes, the more severe the hearing loss. It affects the reception of information, and in mild cases, the quality of the senses is reduced by not being able to hear many subtle sounds, such as music appreciation, and in severe cases, communication is inconvenient. Tympanic membrane repair, also called tympanoplasty, is a routine procedure in otology. The goal of the procedure is to rebuild the middle ear barrier and improve hearing to varying degrees. Many factors affect the success rate of tympanic membrane repair, such as too large a perforation, recent infection, poor eustachian tube, and calcified spots on the tympanic membrane. Therefore, if a small perforation is not healed for more than 6 months or a large perforation is not healed for more than 2-3 months, early surgery should be performed to repair the eardrum to avoid further hearing loss and recurrent pus flow.
