The otitis media tube placement procedure requires the patient to be hospitalized, and because the procedure is aseptic, the implantation needs to be performed in sterile conditions in the operating room. If the patient has a good pain tolerance, local anesthesia can be used. For some people who do not have a good pain tolerance, intravenous general anesthesia is required so that the patient does not feel local pain before the tubes can be placed. The eardrum is a more sensitive area and the pain is more pronounced when the surface is manipulated, which is equivalent to trigeminal nerve pain, so the subjective pain perception index is high. After placement, local cleaning and medication injection into the middle ear cavity are required, and these operations need to be performed in a strictly aseptic environment. Therefore, tympanic tube placement surgery requires hospitalization and treatment in the operating room.
