What is frontal sinuses in respiratory system?

Frontal sinuses are one of the four paired paranasal sinuses located in the human skull. They are situated in the frontal bone, just above the eyebrows. The frontal sinuses are lined with mucous membranes and are connected to the nasal cavity.

The main function of the frontal sinuses is to help warm and moisten the air that we breathe. They also play a role in resonating the voice, and in lightening the weight of the skull.

The frontal sinuses are usually not fully developed until adulthood. In some people, they may not develop at all.

Inflammation of the frontal sinuses is called frontal sinusitis. This can be caused by a variety of factors, including allergies, colds, and the flu. Symptoms of frontal sinusitis may include headache, facial pain, nasal congestion, and fever.

Treatment for frontal sinusitis typically involves antibiotics, decongestants, and pain relievers. In some cases, surgery may be necessary to drain the frontal sinuses or to remove blockages.
