Tympanocentesis is a treatment modality used in otolaryngology to treat secretory otitis media. The main function of tympanic membrane puncture is to draw out the fluid in the middle ear cavity by puncturing it. In addition, medication is delivered to the middle ear cavity through the puncture. There are various methods of tympanic membrane puncture. In the early days, it was performed under the naked eye, but nowadays it is usually performed with an endoscope, because the endoscope can see the entire tympanic membrane more clearly and can be operated more accurately and precisely to avoid other complications. In addition, drugs can be delivered into the middle ear cavity through the punctured area after the puncture, which can speed up the recovery of secretory otitis media. For secretory otitis media, the first step is conservative treatment. After conservative medication treatment has no effect, tympanic membrane puncture treatment can be performed. After repeated tympanic membrane puncture treatment still has no effect, tympanic membrane tube placement treatment is generally recommended.
