Inflammatory diseases of the maxillofacial area

CLASSIFICATION

Odontogenic infections (infections of the oral cavity), depending on the anatomical location, are divided into truly odontogenic

associated with damage to tooth tissue (caries, pulpitis);
periodontal
, associated with damage to the periodontium (periodontitis) and gums (gingivitis, pericoronitis), surrounding tissues (periosteum, bone, soft tissues of the face and neck, maxillary sinus, lymph nodes);
non-odontogenic
, associated with damage to the mucous membranes (stomatitis) and inflammation of the major salivary glands.

These types of infections can cause serious life-threatening complications from the cranial cavity, retropharyngeal, mediastinal and other localizations, as well as hematogenously disseminated lesions of the heart valve apparatus, sepsis.

Purulent infection of the face and neck

may be of non-odontogenic origin and includes folliculitis, furuncle, carbuncle, lymphadenitis, erysipelas, hematogenous osteomyelitis of the jaws.

Specific infections (actinomycosis, tuberculosis, syphilis, HIV) can also be observed in the maxillofacial area.

MAIN PATIENTS

Infections of the oral cavity are associated with the microflora that is constantly present here. Usually this is a mixed flora, including more than 3-5 microorganisms.

With truly odontogenic

infections, along with facultative bacteria, primarily viridans streptococci, in particular (
S.mutans, S.milleri
), anaerobic flora is released:
Peptostreptococcus
spp.,
Fusobacterium
spp.,
Actinomyces
spp.

In case of periodontal infection, five main pathogens are most often isolated: P.gingivalis, P.intermedia, E.corrodens, F.nucleatum, A.actinomycetemcomitans

, less commonly
Capnocytophaga
spp.

Depending on the location and severity of the infection, the patient’s age and concomitant pathology, changes in the microbial spectrum of pathogens are possible. Thus, severe purulent lesions are associated with facultative gram-negative flora ( Enterobacteriaceae

spp.) and
S.aureus
.
In elderly patients and hospitalized patients, Enterobacteriaceae
spp also predominate.

In the conditions of domestic bacteriological laboratories, it is quite difficult to isolate a specific pathogen of a certain odontogenic infection. However, it seems possible to localize pathogens that play a major role in the development of oral infections in supragingival and subgingival plaque.

PRINCIPLES OF TREATMENT OF INFECTIONS OF THE ORAL CAVITY AND MAXILLOFACIAL AREA

Treatment of odontogenic infection

often limited to local therapy, including standard dental procedures.

Systemic antibacterial therapy is carried out only when odontogenic infection spreads beyond the periodontal period (under the periosteum, into the bones, soft tissues of the face and neck), in the presence of elevated body temperature, regional lymphadenitis, and intoxication.

When choosing antimicrobial therapy in a hospital setting, in cases of severe purulent infection, it is necessary to take into account the possibility of the presence of resistant strains among anaerobes such as Prevotella

spp.,
F. nucleatum
to penicillin, which determines the prescription of broad-spectrum drugs, amoxicillin/clavulanate in monotherapy or a combination of fluoroquinolone with metronidazole.
Due to increasing levels of resistance by Streptococcus
spp.
to tetracycline and erythromycin, these drugs can only be used as alternatives. Since metronidazole has moderate activity against anaerobic cocci ( Peptostreptococcus
spp.), simultaneous administration of β-lactam antibiotics is necessary to increase effectiveness.

Preventive systemic use of AMPs when performing dental procedures in the oral cavity or periodontium does not guarantee a reduction in the incidence of infectious complications in somatically healthy patients. Convincing data on the sufficient effectiveness of topical antibiotics for oral infections have not been obtained. At the same time, oral bacteria are a reservoir of determinants of resistance to AMPs. Excessive and unjustified use of antibiotics contributes to their appearance and the development of resistance of pathogenic microflora.

Complications of abscesses and phlegmon

Purulent lesions of the maxillofacial area can be complicated by the following pathologies:

Sepsis is a serious condition of the body that is caused by the penetration of a bacterial infection into the circulatory system. Treatment of such a complication is difficult due to the development of body resistance to antibiotic therapy. Sepsis is often the cause of death. Mediastenitis in the form of purulent inflammation of the tissue of the mediastinum, where the heart, lungs and bronchi are located. Meningitis . Inflammatory damage to the meninges develops as a result of the spread of purulent infection through the lymphatic and blood vessels of the head.

Periandibular phlegmon, photos of which can frighten impressionable people, is always accompanied by an increased number of leukocytes and neutrophils in the blood, a shift in the leukocyte formula to the left and an increased ESR value. The diagnostic sign of phlegmon in the blood serum is C-reactive protein. Protein and white blood cells also appear in the urine.

PURULENT INFECTION OF SOFT TISSUE OF THE FACE AND NECK

Choice of antimicrobials

Drugs of choice: AMPs corresponding to the etiology of the primary source of infection.

Causes and pathogenesis of abscesses and phlegmons

Most purulent lesions of the maxillofacial area are odontogenic in nature. This means that the disease is formed due to the spread of infection from the inflamed root or periodontium. In such cases, streptococci and staphylococci from the primary lesion penetrate through the lymphatic vessels into the deep layers of the soft tissues of the face.

The state of immunity is of great importance in the development of the purulent process. A decrease in the body's protective abilities is a powerful predisposing factor for tissue suppuration.
