1. Odontogenic lymphadenitis develops as a reaction of lymph nodes to any inflammatory process, such as periodontitis, periostitis, or osteomyelitis of the maxilla. 2. Examination of lymph nodes should note size, tenderness, mobility, and whether nodes are single or in groups. Enlarged, tender, and mobile nodes usually indicate acute infection while fixed nodes can be suspicious for malignancy. 3. Diagnosis of lymphadenitis involves sampling fluid from affected lymph nodes for culture to identify the infecting germs. Treatment involves incision and drainage of abscesses, extraction of infected teeth, physiotherapy, and antibiotic therapy.

INTRODUCTION-

3. The major lymph nodes of the head a
nd neck area should be palpated with
the patient in an
upright position. Findings which shou
ld be noted in the patient record incl
ude enlarged palpable nodes, fixed n
odes, tender nodes and whether the
palpable nodes are single or present
in groups. Single or multiple nontend
er, and fixed nodes are very suspiciou
s for malignancy. Groups of tender n
odes usually occur in conjunction wit
h some type of acute infection. Occa
sionally nodes will remain enlarged a
nd palpable after an infection. This is
a relatively common occurrence esp
ecially within the submandibular gro
up of lymph nodes.
When examined, these nodes should be small (less than 1 cm), non-
tender and mobile.

5. Acute and
Chronic
Lymphadenitis
In this form there is an inflammation of the lymph
nodes, but no pus. Acute serous lymphadenitis is in
itial stage of development of the the inflammatory
process in lymph nodes. Start with discomfort, str
etching of the tissues, dull pain, difficulty swallowi
ng and head movements. The lymph nodes are te
nderness, enlarged, mobile with tight
elastic consistency, round and oval shape. An asym
metrical face usually looks and skin over swelling is
without changes. The general condition is not affe
cted and less affected, but in many cases can obse
rve high temperature.
During oral cavity examination the causative tooth
with positive percussion can be revealed.

6. Acute serosal lymphadenitis can turn into Acute
Purulent Lymphadenitis.
Appear considerate increase and indurations of
one or more lymph nodes. They are painless.
Appearance of the morbidity shows the
aggravation of inflammation in the main
focus.Acute purulent inflammation of lymph nodes
of the facial and neck region appears rarer than
chronic (blood changes, leucocytosis, ESR
increase).
Chronic lymphadenitis is the outcome of the acute process in lymph node.
Clinic of the chronic lymphadenitis is characterised by node increasing, by roundish or
oval form, precise and even contours, non solder with surrounding tissues.
During the palpation, the lymph node has solid elastic consistency, and
is painless. General state of the patient, and the body temperature is normal.
Sometimes occurs the capsule fusion of the lymph node and the purulence penetrate i
n the surrounding. In the result develops phlegmonous inflammation -
phlegmonous adenitis, accompanied by the surrounding tissues edema.

7. Adenophlegmon -
Adenophlegmon is an acute purulent
inflammation of the subcutaneous adipose
tissue of an abscessing nature, closely
associated with purulent processes in
regional lymph nodes (lymphadenitis).
This is an external or internal infection,
most often with coccoid flora. As a result of
a decrease in the body’s defenses of an
exogenous-endogenous nature (focal and
perifocal infection, especially in the area of
the tonsils, oral cavity, kidneys, past illness,
skin injury, more often post-injection,
pyococcal lesion of the dermis), the anti-
infective barrier of lymph nodes decreases.
Most often, adenophlegmon occurs in the
parotid and submandibular areas in
children.

8. It is clinically manifested by a manifest tumor
fluctuating under pressure, with hyperemic skin
in the central part, quite dense, painful on
palpation. The general condition of the patient
is characterized by symptoms of intoxication.
Diagnosis, taking into account a typical clinic,
does not cause difficulties, soft tissue
ultrasound, blood tests, punctate treatments
are additionally performed. Treatment
of adenophlegmon consists in immediate
surgical intervention.
Complications -
Advanced adenophlegmon of the
maxillofacial region and neck can cause life-
threatening complications, including
mediastinitis, cavernous sinus thrombosis,
meningitis. With the spread of a highly
virulent infection, the development of sepsis
is not excluded
