If the fluid inside the tympanic chamber is not drained in a timely manner over a long period of time, tympanic membrane puncture and aspiration treatment is performed. Tympanic membrane puncture treatment is simply similar to a gluteal injection, where a slightly thicker needle is injected intramuscularly into the lower front or lower back of the tympanic membrane, and the perforation is very tiny, with a needle hole about the size of a small grain of rice. However, depending on the patient’s condition, the perforation may sometimes be slightly enlarged. As long as the tympanic membrane is not infected, the majority of perforations recover after 1 week.
