Sinus, nose, sinuses
Medical: Paranasal sinus
As the name suggests, the sinuses are located next to the nose in the bony face.
The paranasal sinuses usually become conscious when they become inflamed and sinusitis (= sinusitis) occurs. The paranasal sinuses fulfill important functions that also have to do with heating and humidifying the air we breathe.
If our facial skulls were entirely filled with bones and not by such cavities as the sinuses, our head would be very heavy and we would not be able to hold it upright for long.
Therefore one can ascribe to them the task of weight reduction. The cavities of the paranasal sinuses, together with the main nasal cavity, act as a kind of resonance space for improved voice and language formation.
Singers in particular suffer severe restrictions in their profession due to a sinus infection.

The paranasal sinuses include the paired maxillary sinuses (sinus maxillaris), the frontal sinus (frontal sinus), the pair of ethmoid sinuses with their ethmoid cells (ethmoid sinus and the sphenoid sinuses (sinus sphenoidales). lined.
Since all the paranasal sinuses are connected to the main nasal cavity, the hairs (cinema cilia) beat in the direction of the ducts (ostia).
The maxillary sinus is located on both sides of the main nasal cavity in the upper jawbone (maxilla) and fills it almost entirely. It is one of the largest sinuses. The maxillary sinus has a crescent-shaped opening (hiatus semilunaris) connected to the main nasal cavity. This is located just below the middle turbinate (Concha nasi media). Seen from the jaw cavities, the drainage point is located quite high up, which makes the transport of secretions (e.g. in the case of a cold) difficult.
The zygomatic bone also limits the sinuses.
If the maxillary sinuses are inflamed (maxillary sinusitis), these are particularly badly affected.

The frontal sinus (Frontal sinus) lies above the main nasal cavity and delimits the eye sockets (orbit) from above.
There is also a connection to the main nasal cavity via the crescent-shaped structure (Hiatus semilunaris) in the middle nasal passage (Meatus nasi medius), slightly above the opening of the maxillary sinus.
Inflammation of the frontal sinus (sinusitis frontlis = frontal sinus inflammation) particularly endangers the eye socket (orbit). If too much mucus and pus form, it breaks through into the orbit and the inflammation can spread to the eye (orbital phlegmon, orbital inflammation).

The Ethmoid sinuses (Ethmoid sinus, ethmoid cell) consist of eight to ten pea-sized, pneumatic capsules.
The anterior capsules open into the middle and the posterior capsules into the upper nasal passage (infundibulum ethmoidale). The ethmoid cells become inflamed less often than the maxillary sinus or frontal sinus, but one of the anterior ethmoid cells can force its way into the middle nasal passage (bulla ethmoidales), whereby the middle turbinate (concha nasi medius) is pushed towards the nasal septum.
A bulge in the middle nasal passage makes it difficult to breathe through the nose and can block the other openings in the sinuses.
The Sphenoid sinus (Sinus sphenoidales) has access to the upper nasal passage through a small opening (Recessus sphenoidales; Apertura sinus sphenoidales) above the main nasal cavity.
In the case of inflammatory processes in the sphenoid sinus, it is particularly important to prevent it from spreading to its vicinity. One of the most important neighbors is namely Pituitary gland (Pituitary gland), the important Hormones produced. If inflammation spreads to them, life-threatening illnesses can occur.

Sinus pain can have several causes.
Often times this pain is associated with a cold, but it can also be present without a cold. Although the sinuses are connected to the nasal cavity, the opening is often clogged because they are small in circumference compared to the size of the sinuses.

Especially with colds, ventilation problems and bacterial infections occur. This can be painful and should be treated by a doctor. This pain, which occurs in so-called sinusitis, can be aggravated by leaning the head forward.
If there is no cold with existing pain in the sinuses, then a chronic inflammation is usually to blame. This also clogs the openings in the nasal cavity and creates good conditions for bacterial infection. For this reason, both forms should be treated.
The aim of the therapy is to re-ventilate the paranasal sinuses. For this purpose, a decongestant nasal spray can be administered or the nose can be rinsed. In severe cases, cortisone can also be given. If an existing bacterial infection is suspected, antibiotics are used.

Sinusitis is usually the bacterial inflammation of the sinuses. The mostly purulent inflammation causes the mucous membranes to swell, which obstructs the exits and prevents the purulent mucus from flowing out.

The maxillary sinuses, which are part of the paranasal sinuses, are in close proximity to the deep-lying tooth components such as the root or the nerve of the upper jaw.
Because of this proximity, pathological processes in the maxillary sinuses can easily be transferred to the teeth. This also applies to the pathological processes that take place in the teeth and can easily reach the maxillary sinuses.
A sinus infection is therefore often accompanied by throbbing or stabbing toothache. The toothache is then often accompanied by typical symptoms such as a stuffy nose or sore throat.
Conversely, tooth root inflammation can also cause sinusitis. These usually take a long time and do not include any typical symptoms. If this is the case, a doctor must be consulted, as the focus of inflammation must be eliminated.

Inflammation of the sinuses can also spread to the jaw through the temporomandibular joint. This results in pain when moving within the joint and possibly toothache due to inflammatory processes that spread.

The consumption of alcoholic beverages can lead to a runny or blocked nose. The reasons for this have not been fully clarified.
However, the increased production of nasal secretions and the swelling of the mucous membrane can lead to a ventilation problem in the sinuses. This increases the likelihood of sinus infection, which is usually accompanied by a feeling of pressure and pain.
It can also lead to changes in breathing, which further irritates the mucous membranes.
The popularly named nasal polyps are swollen, bilateral enlargements (hyperplasia) of the nasal mucosa or the mucous membrane of the paranasal sinuses.
They are called polyps because the enlargement of the mucous membrane looks like a fungus on a tree trunk.
The enlargement of the mucous membrane usually starts in the maxillary sinus (maxillary sinus) or ethmoid sinus (ethmoid sinus) and grows in the direction of the middle nasal passage. The nasal passages can be almost completely closed when the growth is pronounced.
The exits (ostia) of the paranasal sinuses located there can be affected by the nasal polyps and almost completely closed. The quality of life can be significantly reduced by polyps.

To get relief from sinus discomfort, various home remedies can be used when the first symptoms appear. For example, it makes sense to inhale warm vapors in order to swell the irritated mucous membranes. To do this, put eucalyptus oil or chamomile flowers in a bowl of hot water and inhale the vapors under a towel for 10 to 15 minutes several times a day. Warming infrared light that is directed onto the sinuses can also accelerate the healing process. However, the use of heat only makes sense if it is perceived as pleasant. In the case of very severe inflammation, the symptoms can be aggravated by heat. Other home remedies for sinus treatment are compresses made of warm water and eucalyptus oil or lemon, in which a linen cloth or washcloth is soaked and then placed on the sinuses. A very important home remedy for sinus infections is high fluid intake to liquefy the mucus. Herbal and peppermint teas can also have a decongestant effect. In addition, care should be taken to ensure that the humidity in the living rooms is sufficient and that cigarette smoke is avoided in the area, as it irritates the mucous membranes.

If the symptoms of sinus infection do not improve despite the use of home remedies, a doctor should be consulted so that the disease can be completely cured and a chronic course can be prevented.
There are several ways to clear mucus from your sinuses and make breathing easier. Saline solutions, which you can either buy ready-made in the pharmacy or make yourself, are suitable for rinsing the sinuses. There are so-called nasal showers that you can use for this. You can also put the rinsing solution in a small bowl, cover one nostril and suck up water with the free nostril. The solution flows through the nose and comes out through the mouth. Rinsing the paranasal sinuses makes it easier to snort off the secretion and the salt water also has a disinfecting effect. Flushing should always be done over a sink, as the amount of mucus that will wash out of your sinuses can be unpredictable. The sinuses should not be rinsed more than four times a day.
Inhaling steam or essential oils can also open the sinuses, moisten irritated mucous membranes and clear the nose of mucus. To do this, you fill a bowl with boiling water (possibly with the addition of essential oils), bend over it with a towel over your head and inhale the rising steam. Just inhaling two to three times a day for a few minutes can effectively relieve the symptoms of a cold or sinus infection. It is important that you rinse the inhaler or bowl well after inhaling and then let it dry as there are bacteria that need little moisture to multiply. Particularly in infants and children, caution should be exercised with essential oils, as they can irritate the airways and trigger an asthma attack, which can lead to shortness of breath in an infant or child.
Expectorants can also be used to rid the sinuses of secretions. Various preparations are available without a prescription in pharmacies or drugstores, such as capsules with the active ingredient Cineolewhich has an expectorant and anti-inflammatory effect within a short time. A cold bath at body temperature can also help clear the sinuses.
However, you should not overdo it with measures to clear the sinuses, as the mucous membranes can be irritated quickly and nosebleeds can occur.
Due to its anatomy, an operation in the sinus area is a very demanding surgical measure that should be carefully considered. An operation can improve the quality of life in the case of a chronic sinus infection, in the majority of cases an operation improves the state of health, especially in people for whom medicinal treatment of the sinusitis does not work. In many cases, however, the symptoms return after the operation, for example nasal polyps that have been removed can grow back after a while.An operation on the paranasal sinuses always carries risks, for example important structures for moistening the nose can be damaged during the operation, which is why dry mucous membranes often occur after the operation. In rare cases, structures near the sinuses can also be injured. This creates the risk of meningitis, inflammation of the eyes or blindness. Temporary consequences of a sinus surgery can be an impairment of the olfactory ability or the bleeding.
Since a chronic sinus infection can have many different causes, it must be decided on an individual basis what type of surgery can help alleviate the symptoms in each individual case. The nasal concha is rarely reduced in size; the typical surgical measure nowadays is a so-called functional endoscopic operation of the paranasal sinuses (in short: FESS). Constrictions or nasal polyps can be removed. This method is very gentle and hardly painful; usually only a day's hospital stay is required after the procedure. The nasal septum can also be operated on endoscopically. There is also the option of shrinking swollen mucous membranes in the area of the paranasal sinuses using laser technology. By reducing the swelling of the mucous membranes, one hopes for a milder course in phases of infection, since blockages in the area of the paranasal sinuses do not occur so quickly. In rather simple cases of chronic sinusitis, a so-called balloon dilatation can be performed. A balloon is inserted into the nose using a catheter and slowly inflated at the entrance to the paranasal sinuses, which allows narrowed openings to be expanded. This method is relatively simple and involves few complications, but it is questionable whether this operation has any long-term benefit.
Even with a chronic sinus infection, a surgical procedure is often not expected to completely disappear; the frequency and severity of the symptoms can be alleviated, but most of those affected still require therapeutic care after an operation.
