They lie next to the nose and have the shape of an inverted pyramid. The maxillary sinus infection can be acute or chronic. In most cases, it is the result of a cold, more rarely, for example, mushrooms, allergies or inflamed tooth roots triggers this sinusitis.

Maxillary Sinusitis: causes and risk factors

The antritis can be caused by other forms of sinusitis such as bacteria, fungi, viruses or allergies. In most cases, it is preceded by a viral infection of the upper respiratory tract (especially the common cold), which may cause an additional bacterial infection due to swelling of the mucous membranes. This eventually leads to antritis (or other sinusitis).

Acute inflammation of the maxillary sinus can also develop if the maxillary sinus mucosa is damaged, for example in tooth extraction in the upper jaw or in fractures of the middle facial skull. Less commonly, maxillary sinusitis originates from the tooth roots of the maxillary teeth (such as tooth root inflammation). Physicians then speak of odontogenic (dentogenic) maxillary sinusitis (or maxillary sinus tubing).

Risk factors of antritis

Various factors favor the occurrence of maxillary sinusitis. In children, for example, these are tonsils that are enlarged due to chronic inflammation (adenoid vegetation). Also, a chronic purulent cold, anatomical bottlenecks in the nose, cystic fibrosis and swimming pool visits can pave the way for an antritis.

Important risk factors in adults include, for example, a curvature of the nasal septum, nasal polyps, allergies, fungal infections, infections in the teeth, opportunistic infections (such as AIDS), intolerance to analgesics (analgesic tolerance) and diving.

Maxillary Sinusitis: Symptoms

An acute sinusitis is associated with dull to throbbing pain and a feeling of pressure in the area of ​​the cheeks (maxillary sinuses). When bending over or hopping on one leg, the symptoms increase. In addition, in an antritis may cause toothache (in the upper jaw), headache, purulent nasal secretions, lower eyelid swelling, increased body temperature and overall fatigue.

Chronic maxillary sinusitis is associated with the formation of bad-smelling secretions in the nose and throat. In addition, there is often pain and pressure in the maxillary teeth of the affected maxillary sinus, but chronic antritis may be painless. Other possible symptoms include headache, coughing (due to secretions draining into the throat), odor disorders and obstruction of nasal breathing. In children, chronic maxillary sinusitis also causes irritability, fatigue and swelling of the lymph nodes.

Maxillary Sinusitis: Diagnosis

First, the doctor asks for the complaints and any existing underlying diseases (collection of medical history = history). Then follows a physical examination: In an antritis, the sampling causes pressure pain over the cheeks. Tapping the front molars (premolars) triggers pain or intensifies existing pain. Even with the rapid bending over of the head occur in the maxillary sinus inflammation pain in the cheek area.

As part of an ENT examination, the doctor will use an endoscope to examine the nose and throat. In maxillary sinusitis, pus is often found in the middle nasal meatus or posterior pharyngeal wall.

Sometimes a swab is taken during the examination to detect the causative agent of the inflammation as well as possible drug resistance (antibiotics).

If necessary, imaging techniques - X-ray, ultrasound, computed tomography (CT) - are also used to clarify antritis.

Also, a blood test (differential blood count, blood cell lowering rate, etc.) and an allergy test can be performed. They provide clues to the exact cause of the sinusitis.

Maxillary Sinusitis: Treatment

Antritis is primarily treated conservatively (non-surgically). An operation is rarely necessary.

Maxillary Sinusitis: Conservative Therapy

In acute antritis and acute episodes of chronic antritis can be applied several times daily decongestant nasal sprays. In addition, the doctor may recommend an anti-inflammatory agent such as diclofenac or ibuprofen. You may also use a herbal remedy (such as myrole or cineole). In allergic maxillofacial inflammation, the doctor will prescribe a locally used cortisone preparation (such as fluticasone), in a by the fungus Aspergillus Inflammation caused an antifungal (antifungal). If the cause of the sinusitis in the area of ​​the teeth (such as tooth root inflammation), this must be remedied by the dentist.

The administration of antibiotics in antritis is indicated only in certain cases. This applies, for example, to evidence of purulent inflammation with severe discomfort and / or fever over 38Β° C, imminent or occurred complications, limited immune defense (as in AIDS) or if the symptoms do not improve or even after five days of decongestants and anti-inflammatory agents even aggravated.

All these conservative measures can provide relief for chronic antritis. However, the inflammation will always come back, unless the cause or existing risk factors (such as anatomical bottlenecks) are eliminated, by surgical means.

Maxillary Sinusitis: Operation

In certain cases of maxillary sinusitis, surgery is necessary. This applies, for example, when antritis with conservative measures can not get under control or has led to serious complications, in maxillary sinus polyps as well as from the maxillary teeth emanating (odontogenic) purulent sinusitis. Thus, for example, the maxillary sinuses are punctured and rinsed with an aqueous antibiotic solution. Even existing bottlenecks (polyps, crooked nasal septum, etc.) are removed surgically, because otherwise it always returns to a Antritis can come.
