What is Sinusitis/Sinus Infection?

Sinusitis is a common condition that occurs due to the inflammation or swelling of the sinuses that surround your nose. Consult Dr Gan to find out more about how to manage your condition.

Sinusitis, or sinus infection, occurs when excess mucus builds up in your sinuses. Sinuses are small, air-filled spaces located in your facial bones that are connected to your nasal cavity or the inside of your nose. Since they surround the nose, they are also known as paranasal sinuses.

Causes of Sinusitis

Viral and bacterial infections

  • Anatomical abnormalities of the nose such as a deviated nasal septum
  • Nasal polyps
  • Allergic rhinitis
  • Tooth infections
  • Fungal infections (usually affects people with a weakened immune system)
  • Viral and bacterial infections

Common Symptoms of Sinusitis

Symptoms of sinusitis vary according to the length and severity of the sinus infection. In general, if you have 2 or more of the following symptoms accompanied by thick, green, or yellow nasal discharge, your doctor may diagnose you with sinusitis.

  • Blocked or runny nose
  • Postnasal drip
  • Thick nasal discharge
  • Reduced sense of smell and taste
  • Pain and tenderness around your cheeks, eyes or forehead
  • Cough or congestion

How is Sinusitis Diagnosed?

Sinusitis can be diagnosed by the following methods.

Physical Examination

To diagnose a sinus infection, your doctor will ask you about your symptoms and do a physical examination. They may gently press a finger against your forehead and cheeks (over your sinuses) to check for pressure and tenderness. They may also examine the inside of your nose with a light source to identify inflammation, nasal polyps, or other abnormalities.

However, if your symptoms persist, your doctor may refer you to a sinus specialist for further examination.

Using Nasal Endoscopy

Your sinus specialist may perform nasal endoscopy – a procedure to take a closer look at the nasal and sinus passages.

During the procedure, an endoscope (a small, thin, and flexible tube with a light and camera attached) will be inserted into your nose and be guided through your nasal and sinus passages.

Detailed images of the areas will be visible through the endoscope. A sample may also be obtained for culture testing to test for the presence of an infection.

Imaging Tests

In some cases, your sinus specialist may order a CT scan or MRI to determine if there is mucus blockage or any abnormal structures such as polyps in your nasal passages and sinuses.

Other tests

Your doctor will ask you about your symptoms and perform a physical examination to diagnose a sinus infection. They may gently press a finger against your forehead and cheeks (over your sinuses) to check for pressure and tenderness. They may also examine the inside of your nose with a light source to identify inflammation, nasal polyps, or other abnormalities.However, if your symptoms persist, your doctor may refer you to a sinus specialist for further examination.

Sinusitis Treatment

The treatment options vary depending on how long the symptoms last. A combination of options may also be used to treat your sinus infection.


In general, acute viral or early bacterial sinusitis may resolve without antibiotics. However, if your symptoms are more severe, your doctor may prescribe antibiotics. Antibiotics help eliminate a sinus infection by attacking the bacteria that causes it, but until the drugs take effect, they do not do much to alleviate symptoms. A typical course is usually between 7-21 days depending on your doctor’s instructions. Side effects include rashes, diarrhea, or stomach issues.

Don’t stop taking your antibiotics earlier than instructed as this can allow the bacterial infection to fester and not be fully resolved. On the other hand, the overuse of antibiotics can lead to superbugs, which are bacteria that cause serious infections and cannot be easily treated.

Your doctor may have you schedule another visit to monitor your condition.

Nasal Corticosteroids

Nasal corticosteroids (nasal steroid sprays) are used to prevent and treat inflammation. They are also effective in shrinking and preventing the return of nasal polyps. They are available over the counter or by prescription. Your doctor may also direct you to rinse your nasal cavity with a saline solution mixed with a corticosteroid such as budesonide.

Oral Corticosteroids

Oral corticosteroids are usually prescribed if you have nasal polyps or a severe case of sinusitis. They are typically only used to treat severe symptoms

Other tests

Antifungal drugs can be prescribed to treat a fungal infection but this is rarely needed. Allergies can be treated with antihistamines or allergy shots. Avoiding exposure to allergens in general can reduce the occurrence of allergic sinusitis

Sinus surgery

If you are responding to the above treatments, your sinus specialist may opt to perform functional endoscopic sinus surgery (FESS) or balloon sinuplasty.
Treatment may still be required following surgery to prevent the return of sinusitis.
Take note that insurers may require patients to provide in-depth evidence to show that surgery is for sinusitis and not for cosmetic surgery (to improve the appearance of your nose).

Functional Endoscopic Sinus Surgery (FESS)

FESS is usually performed under general anesthesia (when you’re asleep) and patients can often go home on the same day. During the procedure, the surgeon will insert an endoscope into your nose. It is a thin tube with a lens at one end that magnifies the inside of your nose. It allows the surgeon to see the opening of your sinuses and insert small surgical instruments.

The purpose of this surgery is to widen the natural drainage pathways between the sinuses and the nasal cavity, allowing mucus to get out of the sinuses. Hence, the surgeon will remove any thin bony partitions or tissues such as nasal polyps that are blocking the affected sinus. Potential common side effects and risks of this procedure include temporary discomfort and crusting inside the nose, bleeding from the nose, and infection. Ensure that you discuss the risks with your surgeon beforehand.

Balloon Sinuplasty

Balloon sinuplasty is typically performed in patients who have chronic sinusitis. This procedure is regarded as less invasive than traditional sinus surgery as it does not involve the removal of bone or tissue from the nose. It can be performed under local (temporary loss of sensation or pain in one part of the body) or general anesthesia. During the procedure, your surgeon will insert an endoscope into your sinus cavity. Next, they will insert a thin and flexible balloon catheter into your sinus passage. The balloon is slowly inflated to enlarge your sinus openings after which the surgeon will flush out built-up pus or mucus in the sinus cavity with saline solution.The balloon is then deflated and removed, leaving your sinus passages widened and sinuses free of built-up pressure.

Risks of this procedure include a slight alteration to the appearance of your nose after the surgery and infection. Ensure that you discuss the risks with your surgeon beforehand.

The head & neck region is a complex area that houses important organs and structures, including the ear, nose, and throat.

An unhealthy or problematic nose & sinuses can lead to other complications such as worsening of Asthma, snoring and obstructive sleep apnoea (OSA).

Allergic reactions are commonly characterised by a runny nose, stuffiness and persistent sneezing.

Unlike adults, children may not be able to express some of their symptoms accurately.

Throat and voice problems can affect and damage the throat if left undiagnosed and untreated.

Elderly ENT conditions can result in severe complications if left undiagnosed and untreated.
