About Acute Sinusitis
The pathophysiology of acute sinusitis involves several factors:
- Infection: Acute sinusitis is commonly caused by bacteria, such as Streptococcus pneumoniae and Haemophilus influenzae. These bacteria can infect the sinuses and trigger an inflammatory response.
- Allergy: Allergic rhinitis can lead to the development of acute sinusitis. When a person with allergies is exposed to allergens, such as pollen or dust mites, it can cause inflammation in the nasal passages and sinuses, increasing the risk of sinus infection.
Non-modifiable (things that cannot be changed) risk factors for acute sinusitis include:
- Anatomic abnormalities: Structural problems within the sinuses, such as nasal polyps or deviated septum, can obstruct the normal flow of mucus and increase the risk of sinus infection.
Modifiable (things that can be changed) risk factors for acute sinusitis include:
- Smoking: Smoking damages the lining of the respiratory tract, making it more susceptible to infections, including sinusitis.
- Exposure to second-hand smoke: Being exposed to second-hand smoke can also irritate the sinuses and increase the risk of infection.
It's important to note that these risk factors may vary from person to person, and individual susceptibility to acute sinusitis can differ. If you have concerns about your risk factors or symptoms, it's best to consult with a healthcare professional for personalized advice.
The most common early symptoms of Acute Sinusitis include:
- Facial pain around the eyes or forehead
- Nasal discharge
- Feeling of pressure behind the eyes
- Inability to smell
- Cough that worsens at night
- Feeling unwell (malaise)
- Mild or high fever
- Tiredness
- Sore throat
- Unpleasant or sour breath
As Acute Sinusitis progresses or becomes more severe, additional symptoms may occur, such as:
- Thick green nasal discharge
- Headache
- Thickened or hardened mucus blocking nasal passages
- Mucus leaking down the back of the throat (postnasal drip)
- Tenderness or discomfort in the face, especially around the eyes, forehead, and cheeks
It's important to note that symptoms can vary depending on which sinus is affected. For example, frontal sinusitis may cause pain in the forehead that worsens when lying down, while ethmoid sinusitis may cause pain between the eyes and loss of smell. If you experience any of these symptoms, it's best to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.
To diagnose Acute Sinusitis, doctors commonly perform the following examinations, tests, and procedures:
- Physical examination: The doctor may tap on your frontal sinuses to assess pain and tenderness. They may also check your nasal cavity for signs of polyps and inflammation.
- Nasal endoscopy: This procedure involves using a thin tube with a light and imaging source to capture pictures of the inner sinuses. The doctor can then view these pictures on a computer screen to assess the condition of your sinuses.
Additional examinations, tests, and procedures to determine the stage or severity of Acute Sinusitis may include:
- Imaging tests: CT or MRI scans can provide detailed images of the sinuses, helping doctors assess the extent of sinusitis and identify any underlying causes.
- Allergy tests: These tests can help identify if allergies are contributing to sinusitis symptoms.
- Blood tests: Blood tests may be conducted to rule out other possible causes of sinusitis or to assess immune function.
- Nasal culture: A sample of mucus from your nose may be taken to check for infection.
- Transillumination: This involves shining a light against the sinus area to look for signs of inflammation.
Remember, these examinations, tests, and procedures should be performed by a healthcare professional. They will determine which ones are necessary based on your specific situation.
The goals of treatment for acute sinusitis include:
- Treating the underlying cause: Identifying and addressing the cause of sinusitis is crucial for effective treatment. This may involve treating infections, allergies, or other factors contributing to sinus inflammation.
- Reducing inflammation: Inflammation in the nasal passages can prevent proper drainage and exacerbate symptoms. Medical therapies that aim to reduce inflammation include:
- Intranasal corticosteroids: These medications, such as fluticasone and mometasone, reduce swelling in the nasal passages, allowing mucus to exit more easily and improving breathing.
- Oral corticosteroids: In cases where intranasal steroids are insufficient, short-term oral corticosteroids may be prescribed to further reduce inflammation.
- Thinning nasal secretions: Thinning the mucus in the sinuses can help improve drainage. This can be achieved through medical therapies such as hypertonic saline solution or nasal decongestants.
- Clearing up symptoms and preventing recurrence: Medications like antibiotics may be prescribed if a bacterial infection is present. Over-the-counter nasal sprays or decongestants can provide temporary relief by unblocking the sinuses and reducing congestion.
It's important to consult with a healthcare professional before starting any medication or therapy. They can provide personalized recommendations based on your individual situation. Additionally, health behavior changes like staying hydrated and practicing good nasal hygiene can also support treatment goals.
Medication dosing may be affected by many factors. Check with your healthcare professional about dosing for your individual situation. Side effects can occur. Check with your healthcare professional or read the information provided with your medication for side effect information.
