What does the sinuses do?

Your sinuses are air spaces in your skull and facial bones that make up the upper part of your respiratory tract from your nose into your throat. The sinuses are in your forehead (frontal sinuses), inside your cheekbones (maxillary sinuses), and behind the nose (ethmoid and sphenoid sinuses).

What are sinuses and what purpose do they serve in the skull?

The skeletal system
QuestionAnswer
What are sinuses?mucosa-lined air- filled cavites in the bone.
What purpose do they serve in the skull?They lighten the skull serve as resonace chambers for speech
Why are they so susceptible to infection?their mucosa is continous with that of nasal passage into which they drain.
  • What is a sphenoid sinus infection?

    Isolated sphenoid sinusitis is a rare disease with potentially devastating complications such as cranial nerve involvement, brain abscess, and meningitis. It occurs at an incidence of about 2.7% of all sinus infections. 2. Although headache is the most common presentation symptom, there is no typical headache pattern.
  • What are the causes of a sinus headache?

    Sinus headaches are usually caused by an infection and inflammation of the nasal passages. That leads to congestion. And that causes pain and pressure in the forehead and behind the cheekbones.

B.

Why do we need your sinuses?

Function. The presence of sinus cavities within the cranial bone (skull) is essential for the following reasons: Sinus cavities allow for voice resonance. They help filter and add moisture to any air that is inhaled through the nasal passages.
  • Where does all of the snot come from?

    A stuffy nose, then, is your body's attempt to block and expel an infection attacking via your respiratory tract. The extra secretion of mucus to the nose — which comes from the cells that line your sinuses and upper reparatory tract — is the effort to flush out the nasal passages to send those unwelcome germs packing.
  • How do I get my sinuses to drain?

    7. Exercise.
    8. Perform a manual massage.
  • What is the difference between a sinus and a fistula?

    A fistula is an abnormal pathway between two anatomic spaces or a pathway that leads from an internal cavity or organ to the surface of the body. A sinus tract is an abnormal channel that originates or ends in one opening. In the literature, the terms fistulas and sinuses are often used interchangeably.
C.

How does the sinus work?

With healthy sinuses, the air circulates freely through the chambers and mucus drains into the nose. When the sinuses are free of swelling and thickened mucus and the cilia are working correctly, your sinuses drain freely, which keeps the sinuses clean.

  • Can sinus infection spread to brain?

    Also in rare cases, sinus infections in the rear center of one's head can spread into the brain. This can lead to life-threatening conditions like meningitis or brain abscess, Dr. Sindwani says. “Before antibiotics, people would die from sinusitis,” he says. But he emphasizes that such complications are unlikely.
  • What is ethmoid sinus disease?

    Your ethmoid sinuses are located near the bridge of your nose. Sinuses help to filter, clean, and humidify inspired air. They also keep your head from becoming too heavy. Ultimately, mucus made in the sinuses will drain to the nose. Upper respiratory infections or allergies can ultimately lead to ethmoid sinusitis.
