Ear fluid puncture should be considered clinically as a tympanocentesis for secretory otitis media. Common risks include: pain, bleeding, non-healing of the tympanic membrane, infection, and induction of suppurative otitis media.
1. Pain: Although tympanocentesis is a minor surgery, there are still sensitive nerves on the surface of the tympanic membrane, and surface anesthesia with lidocaine or bupivacaine can be used if possible to reduce the pain and discomfort.
2. Bleeding: There are still capillaries on the surface of the tympanic membrane, and puncture may cause a small amount of bleeding, which can be stopped on its own. If the patient has blood-related diseases, such as thrombocytopenia, abnormal coagulation mechanism, it may increase the risk of bleeding.
3. Non-healing of the tympanic membrane: The puncture point is usually very small, the size of the tip of a needle, and the vast majority of puncture points are able to heal on their own. If there is water in the ear canal, the puncture point may not heal.
4. Infection, induced suppurative otitis media, etc.: If the puncture operation does not follow the principle of asepsis, bacteria may be brought into the middle ear cavity, inducing infection or even suppurative otitis media.
Therefore, if you intend to do tympanic membrane puncture, it is recommended to go to a regular hospital and standardize the operation and treatment.
