Patient’s question: Description: 5-year-old boy, a year ago found glandular hypertrophy and sinusitis, rhinoscopy blockage 80%, conservative treatment for a year to date, sinusitis recurrent, yellow pus nasal mucus, each time taking antibiotics for two to three weeks, spraying Nesuna will be good, every two months, after the cold or other reasons relapse, repeated several times in a year. In June this year, the gland was 85% blocked, but in the summer it was basically fine. When it was cool, the snoring could not be relieved by lying down, but it was relieved by lying on the side, and sometimes it was not. The breath sounds were coarse, and the tonsils were not enlarged. Hope to provide help:Are adenoidal hypertrophy and sinusitis directly related to each other? Can sinusitis be prevented from recurring if adenoids are operated on? Taking antibiotics for a long time is too damaging. Or is sinusitis just hard to cure and control, and is there any other treatment besides antibiotics? Thank you very much! Chen Yanqiu, Department of Otolaryngology, Guangzhou Women’s and Children’s Medical Center, replied: Adenoid hypertrophy can lead to nasal dysfunction, and when the function of nasal ventilation and drainage is seriously affected, it can easily lead to sinusitis. This means that sinusitis can occur when a child has a cold or flu, and it takes longer to treat. This may happen less often in the summer, but it occurs more often in the spring and winter when they are prone to respiratory infections. If the nostrils are still more than 80% blocked by adenoids after more than 1 year of medication, and if there is a history of recurrent sinusitis attacks and clinical symptoms of restless sleep, surgical treatment may be considered. Generally speaking, after adenoids are removed, the ventilation and drainage of the nasal cavity is restored and the chances of sinusitis occurring are significantly reduced. Of course, it can not be said that sinusitis will not be committed, it may be said that the possibility of suffering from sinusitis is very small, and even if sinusitis occurs, it medication is easy to treat and the course of treatment is shortened.
