what is sinuses
Answers
Sinusitis is a type of disease that attacks the sinus wall, which is a small cavity located inside the skull bone, on the back of the nose
Discussion :
Sinusitis, also known as sinus infection or rhinosinusitis, is an inflammation of the mucous membrane lining the sinus wall.
Sinusitis can be caused by infection, allergies, air pollution, or structural problems in the nose. Most cases of sinusitis are caused by viral infections. Bacterial infections can occur and cause chronic sinusitis.
Symptoms of sinusitis include headache, facial pain, runny nose, and stuffy nose. Other signs and symptoms may include fever, a weakened sense of smell, sore throat, and coughing. This sinus cough is often worse at night.
Serious complications are rare, but acute sinusitis can occur if it lasts about 4 weeks, and chronic sinusitis can occur if the condition lasts more than 12 weeks.
Acute sinusitis usually does not require any treatment other than relieving symptoms with a decongestant or pain reliever. Acute sinusitis can be triggered by a cold or allergy and can heal by itself.
Chronic sinusitis can be caused by a bacterial infection and requires antibiotics to overcome the infection that causes this condition.
Answer:
The respiratory sinuses are air-filled, mucous-membrane lined cavities within the skull and facial bones surrounding the nose. There are four pairs of sinuses in the body that produce mucous. This mucous is drained out the nasal cavity. Sinuses help to warm and moisten the inhaled air. They produce mucus that helps to trap dust, microbes and other particles. Sinus cavities help in speech production, too.
