Sinusitis is a common disease affecting the nasal cavity area. It is an acute or chronic inflammation (with periods of remission and exacerbation
of symptoms). Sinusitis is considered chronic, in which the purulent inflammation lasts more than 3 months. According to the inflamed sinus anatomy, it can be differentiated into maxillary, frontal, ethmoid, and pansinusitis. The maxillary sinus is most commonly affected. A common cause of sinusitis is a seemingly harmless runny nose. Sometimes there is an infection (sinusitis) behind a harmless runny nose that does not go away for more than a week. Another reason is the curvature of the nasal septum, enlarged third tonsil, teeth problems, etc. The most common symptoms of sinusitis are headache, pain, and heaviness in the eyes and cheekbones area. Sinusitis may also provoke a cough. It is due to the flow of secretions from the nose down the throat and trachea.
The following complications are observed in sinusitis – orbital cellulitis, meningitis, permanent loss of smell, brain abscess, ear infection, encephalitis, etc. The diagnosis is made after assessing the symptoms, X-ray, computed tomography scan, ultrasound, etc.
