Sinus or sinusitis is one of the most common diseases in some parts of the world. More than 9 million cases are caused by sinusitis and cost about $102 million just for treatment.
Sinusitis is inflammation of the sinus, the air-filled cavity that can be found in various parts of the skull: the frontal (the lower part of the forehead), the maxillary (the cheekbone), the sphenoid (the back of the nasal cavity), and the ethmoid (between the bridge of the nose and the eye). The four parts of the skull are known as paranasal sinuses.
Sinus Infection Symptoms Factors
Sinusitis or sinus infection symptoms is caused by certain factors, ranging from congenital abnormalities to viruses or bacteria, leading to sinus inflammation. Then, the sinuses will produce a very thick mucus, so the cilia cannot push the mucus into the throat.
Sinusitis has many types that are usually distinguished by its duration:
- Acute – Acute sinusitis occurs suddenly, but also does not last long. In fact, sinus inflammation usually goes away on its own, or can be cured with ordinary drugs like antibiotics.
- Sub-acute – Sinusitis is considered sub-acute if it occurs for more than 3 weeks but less than 12 weeks.
- Chronic – When a person has sinusitis for up to 3 months, it means that sinusitis is chronic. Although sinusitis persists for a long time but is usually not severe.
- Contagious – Sinusitis is usually not contagious, although it is caused by bacteria. However, when sinusitis occurs due to a virus, such as a cold or flu virus, the sinusitis becomes easily transmissible and is usually transmitted through the touch of a hand.
