Chronic sinusitis is a disease with nasal congestion, runny nose and headache as the main manifestations, which are the three typical symptoms of sinusitis, accompanied by loss of smell, memory loss and other obvious systemic symptoms. The disease has a long course, from several years to decades, with recurrent attacks that are difficult to cure. The majority of chronic sinusitis is a variety of bacterial infections in the sinuses.
Clinical manifestations 1, runny: mostly purulent, yellow, green or gray-green, pus can often flow through the posterior nostril through the nasopharyngeal cavity to the pharynx, the patient feels that there are secretions in the pharynx, and often spit out after the pharynx suction.
2, nasal congestion: caused by nasal mucosa congestion, inferior turbinate and middle turbinate hypertrophy or nasal polyps, sometimes also due to too much pus, nasal congestion is reduced after blowing out the secretions.
3, headache: chronic sinusitis is mostly manifested as a heavy head, acute attacks can have a headache, or only dull pain or boring pain, the location is relatively fixed, the time also has a certain pattern, but there are also not fixed, are due to poor drainage in the sinuses 4, hyposmia: mostly for the first two reasons, one is the nasal mucosa swelling, nasal blockage, airflow can not enter the olfactory area, the second is the olfactory area mucosa by chronic inflammation of long-term stimulation The second is chronic inflammation of the mucous membrane in the olfactory area, and the olfactory function is reduced or disappeared.
5. Systemic manifestations: a few people may have no obvious symptoms, but most of them have dizziness, loss of appetite, easy fatigue, poor concentration, memory loss and insomnia, etc.
Examination and diagnosis 1, rhinoscopy or nasal endoscopy: chronic congestion and swelling of the nasal mucosa, the area of the sinus opening can be seen with purulent secretions, more intuitive.
2.X-ray, CT or MRI examination: uniformly increased density in the diseased sinus cavity. Generally more commonly used CT examination, CT scan can make the lesion of the sinus more clearly revealed.
3, maxillary sinus puncture and irrigation: used both for examination and diagnosis, as well as for treatment.
In addition, chronic sinusitis should be distinguished from chronic rhinitis and acute sinusitis, and should also be distinguished from neuropathic headache for early diagnosis and early treatment.
