This picture depicts a CT scan image of paranasal sinuses with collection of pus in the sinuses on the left side. Sinusitis The sinuses are air filled cavities located in the bones of the face. The sinuses are divided into groups based on their location and are named maxillary, ethmoid, frontal and sphenoid sinuses. Sinusitis is inflammation or infection of one or more of the sinuses. Depending on the age of the child, infection may occur in the pair of sinuses located between the eyes (ethmoid) and/or the pair behind the cheekbones (maxillary), as both of these sinuses are present at birth. As children get older, they develop a pair of frontal sinuses (in the forehead) and a pair of sphenoid sinuses (behind the nose), which can also become affected. Sinusitis has symptoms of runny nose, stuffy nose, fever, headache, cough (especially at nighttime), post nasal drip (causes frequent throat clearing), bad breath, facial swelling and bleeding. Many times it is difficult to tell the difference between a cold and a sinus infection. A cold has many of the same symptoms but will usually get worse around the 3rd or 4th day and be improving by a week to ten days. A sinus infection is usually worsening instead of improving at a week to ten days. Sinusitis is caused by an infection within the sinus cavities. Anything which causes blockage of the natural drainage openings of the sinuses can lead to infection. This means colds, flu, allergy or bacterial infection may be responsible. Blockage may also occur from POLYPS, which may be caused by allergies or chronic infection. Once blockage of the natural drainage passageways has occurred,mucoid secretions are collected. This may lead to inflammation and, eventually, infection of trapped mucus, otherwise known as acute sinusitis. Diagnosis of sinusitis based mostly on the history. Sinusitis is also diagnosed by how long the symptoms last. If the child has a simple cold or flu, symptoms will usually last from 7 to 10 days. If the symptoms described previously persist beyond ten days, sinusitis is likely to have occurred and your child should be evaluated by a physician. The next step is an examination of the patient's ear, nose and throat. Occasionally special nasal endoscopes will be used to see farther into the nose. In addition, your doctor might order x-rays to completely evaluate the sinuses. These x-rays may include plain x-rays of the sinuses or a computed tomography (CAT) scan, which will give your doctor the most accurate information. As the first line of treatment, antibiotics are given for several weeks to clear the sinus infection. Nasal decongestants or nasal sprays may also be prescribed. If the diagnosis is acute sinusitis, symptoms should improve within the first few days.Three week course of antibiotics has to be given to prevent recurrence of infection. . chronic sinusitis which does not seem to go away completely with antibiotics, need surgical treatment of the sinuses using FUNCTIONAL ENDOSCOPIC SINUS SURGERY (FESS). Other procedures such as SINUS CULTURE or ADENOIDECTOMY may also be recommended. Serious complications of sinusitis include orbital cellulitis (an infection in the tissues around the eye), osteomyelitis (an infection in the bones), meningitis (infection in the fluid surrounding the brain and spinal cord),or brain abscess. These complications are rare.
