Paranasal sinuses: anatomy and function photos

What is paranasal sinuses?

In the formation of respiration involves several organs, including the trachea, sinuses, larynx and nasal cavity. Anatomy and function of the sinuses is not known to everyone, despite the fact that they play an important role.

Knowing the structure and role of the sinus, it is possible to minimize the risk of chronic diseases, illnesses and severe complications. At the slightest defeat of these bodies need to take urgent measures to prevent negative consequences.

Anatomy of the paranasal cavities

Almost 95% of the population of the planet has 4 pairs of sinuses and they are all in the bones of the facial skull:

  1. The ethmoid labyrinth.
  2. Maxillary (maxillary).
  3. The frontal (front).
  4. Basic (wedge).

Anyway, they are all connected with the nasal cavity and are lined with a special mucous membrane. Because of this, almost every inflammation of the mucous membrane of the nose, sooner or later will go to the region of the sinuses.

You need to be very careful with the inflammation of the mucous membrane, as due to small amounts of nerve endings, the initial stage of destruction is practically free of any visible symptoms. It becomes clear there is a problem when it already becomes acute stage.

Newborns paranasal sinuses are underdeveloped and paranasal finally formed approximately by the age of 20.

Maxillary cavity

If you don’t know what is paranasal sinus of the nose, named after the scientist who described it, it is the maxillary. This is the largest sinus of all. They are in the upper part of the jaw, because of what they are called maxillary.

On the form, these sinuses are like a pyramid with three faces. The lower bound is so close to the roots of the teeth of the upper jaw, which is necessary to be very attentive to oral hygiene and at the slightest problem, to instantly respond to them. It can threaten an inflammation of the sinuses.

As for upper bounds, it is in proximity to the eye socket. As soon as possible to respond to inflammatory processes, as they can give serious complications on eyesight.

The thickest wall is considered the front. The rear panel has so-called anastomosis, which is the conduit through which this cavity is air. When it is clogged, it will start the inflammatory process.

Main cavity

The sphenoid sinuses are in the sphenoid bone of the face. In comparison with the others, these cavities are considered to be unpaired. They have a special partition that divides them in half. Shares do not communicate directly among themselves and often have a different volume.

Each cavity has multiple partitions:

  • front;
  • rear;
  • bottom;
  • top;
  • medial (internal);
  • lateral (shares the cavity with the important organs).

The frontal cavity

Frontal the sinuses located deep in the bones of the zygomatic arches. If they are prone to inflammation, palpation through the front wall, you can feel the pressure and pain.

Inside there is a special partition that separates the sinus into two. Often they are different sizes. This is due to the fact that the bone wall is not located exactly in the middle.

The ethmoid labyrinth

The location of a trellised labyrinth is located between the frontal and sphenoid cavities. He is represented in the form of cells, the number of which reaches 10-15 on each side. They all have a message, not only among themselves but also with the nasal cavity.

There is one unique feature, you’ll trellised labyrinth individually. The cell may be located in the front/rear sections or in the eye socket.

The role of the paranasal cavities

Paranasal cavity simultaneously perform several essential and non-essential functions:

  • speech. Due to the cavity creates the uniqueness of the voice tone;
  • olfactory. Is the ability to recognize odors and flavors;
  • protective. Due to the presence of cilia and mucous membranes, all chemical elements bearing damage, delayed and did not enter the body;
  • respiratory. Before entering the lungs, the air is warmed if necessary, and purified.

Any quality photo of computed tomography can clearly show the location and structure of the paranasal sinuses. It is very important when the first symptoms to immediately consult a specialist for diagnosis and early treatment while the disease did not progress to a more serious form.
