Recently, many families of children have asked the same questions about how to diagnose adenoid hypertrophy, whether surgery is necessary, what is the conservative treatment method, etc. Therefore, I write a diagnosis and treatment process for the families of children for reference. 1. If a child (generally 2-8 years old) has symptoms such as recurrent nasal congestion (obvious at night), runny nose, snoring at night, breath-holding, open-mouth breathing, repeated throat clearing, etc., consider the possibility of adenoid hypertrophy; 2. outpatient examination, nasal endoscopy; 3. lateral nasopharyngeal film; 4. active treatment after diagnosis, see my related article “The danger of adenoid hypertrophy” for obvious nasal symptoms, especially For children with allergic diseases, such as allergic rhinitis and asthma, you can try nasal hormone therapy, see my article “Nasal hormone therapy for sleep apnea hypoventilation syndrome in children”, the drug is usually mometasone furoate nasal spray (Nesuna) fluticasone propionate nasal spray (Fusarium) budesonide nasal spray (Renolcort), the efficacy of 8-12 weeks is more appropriate, no symptoms after also adhere to the a period of time. General treatment after 1 month to the hospital for follow-up. 5.If conservative treatment is not effective, surgical treatment can be considered, and most children have their tonsils and adenoids removed together. (3) surgical appliances, “the choice of common surgical equipment for adenoids surgery”, currently our department mainly uses plasma radiofrequency, fast surgery, less bleeding, light postoperative pain, more importantly, it may deal with the adenoid tissue around the eustachian tube and posterior nostril, greatly reducing the recurrence rate. 6, of course, all surgeries have risks, see “adenoids, tonsillectomy surgical risks”, the family must be prepared in mind; 7, post-operative common problems, “adenoids, tonsil post-operative common problems”.
