If the adenoid hypertrophy leads to secretory otitis media, it needs to be treated at the same time during surgery. Generally, if the otitis media is not very serious, the course of the disease is not very long, the intraoperative microscopic examination reveals that the fluid is not too much and not sticky, and the child’s hearing is not affected, it is possible to perform tympanocentesis or tympanotomy during surgery and extract the fluid. However, if the child has hearing loss and the intraoperative examination reveals a lot of fluid or very sticky fluid, it is recommended that a tube be placed. After tube placement, usually the ears should not enter water or swim. After six months, most of the tympanic membrane ventilation tubes will gradually fall off, if not, follow up again and remove the tubes according to the situation. Most of the tympanic membrane will heal within a month after tube removal, but a few will have small perforations.
