Main etiology: Mostly due to untimely or effective treatment of acute sinusitis (symptoms within 12 weeks) or recurrent episodes resulting in adenoid hypertrophy or infection: nasal obstruction leading to abnormal mucosal function of the nasal cavity and sinuses. Allergic factors: 65% of children with sinusitis are associated with allergic reactions. Main manifestations: Nasal congestion and purulent nasal discharge Facial or headache: younger children are usually unable to give an accurate account and often present as irritability, irritability or crying. Chronic cough Behavioral changes: mental depression, poor memory, inactivity, etc. Hearing loss: Mostly secretory otitis media due to adenoid hypertrophy and pharyngeal edema Examination methods: Similar to adults, CT or nasal endoscopy of sinuses is usually performed. Treatment: Chronic sinusitis in children can have a tendency to heal spontaneously after puberty, so it can usually be controlled by pharmacological treatment, routinely using a combination of antibiotics, local glucocorticoids, mucus promoters, nasal rinses (for children who can cooperate), etc. for more than 3 months. At this point, a systematic evaluation is needed, including symptom scores, CT scans of the paranasal sinuses, etc. If the evaluation results suggest that the treatment is ineffective, then nasal endoscopic surgery should be considered. In summary, “medication” and “surgery” are both treatments for “chronic sinusitis” and are complementary to each other, and only a reasonable choice of surgery, together with comprehensive medication, can achieve the best The best treatment effect can be achieved only if surgery is chosen reasonably and combined with comprehensive medication. In the process of treatment we should avoid the following two situations: Fear of surgery, resistance to surgery Some people think that surgery is invasive, as long as the surgery will inevitably cause some harm to the body, hearing the word “surgery” will instinctively produce resistance to emotions. There are two sides to everything, there are advantages and disadvantages, drug treatment can only be effective if it reaches the lesion, for severe “chronic sinusitis” long-term drug treatment is ineffective patients, the nasal mucosa is highly edematous, or accompanied by nasal polyps nasal obstruction, only a reasonable choice of surgical treatment to remove the nasal lesion in a timely manner, for Only a reasonable choice of surgical treatment can remove the nasal lesion in time, provide a route of administration for drug treatment, achieve the best therapeutic effect, and significantly improve the quality of life. In contrast to the “fear of surgery”, some patients who have been suffering from “chronic sinusitis” for a long time and have not undergone comprehensive drug treatment are eager to have surgery, believing that “surgery The “surgery” can solve all the problems and quickly improve the symptoms. First of all, we must get out of the misconception that “surgery is better than medication to remove the root”, not all patients with chronic sinusitis must be treated surgically, and even in a sense, a significant portion of patients with chronic sinusitis can improve their symptoms through systematic medication. Especially for patients with “chronic sinusitis without nasal polyps”, surgery without medication may be overkill, and even postoperative symptoms such as empty nose and strong irritation in the nasal cavity may occur. Therefore, the choice of surgical treatment should be timely and cautious. Only the correct choice of treatment plan, surgical removal of lesions, together with comprehensive drug treatment can maximize the therapeutic effect and better maintain your health and high quality of life.
