Abstract.
Benign odontogenic tumors of epithelial origin are a group of
diseases that, due to the variety of clinical course, pathomorphological features and
various treatment options, are of great interest to clinicians. Ameloblastoma is a
benign odontogenic tumor with an aggressive clinical course, which is formed from
an odontogenic epithelium in a mature fibrous stroma devoid of odontogenic
ectomesenchyma.
The purpose of the study: to study the MSCT semiotics of ameloblastoma.
Materials and method.
We examined 20 patients with ameloblastoma.
The age of the patients was 20-33 (2±1.2). Among them, 12 patients were women,
8 patients were men. Multispiral computed tomography (MSCT) was performed
in spiral mode on the Somatom Emotion 64 device (Siemens, Germany). MSCT
with contrast was performed after a native study with the introduction of a
contrast agent (nonionic contrast agent Unigexol (2 ml/ kg Unigexol 350 mg
iodine/ml, Unique Pharmaceutical Laboratories, India) with subsequent
scanning.
Results.
At MSCT, small tumors were detected in 8 patients (40%)
characterized only by marginal contrast enhancement, in 12 patients (60%) –
large volumetric formations spreading beyond the bone, containing a solid
component that moderately accumulates contrast, and low-density cystic areas.
All 20 patients (100%) had no spread beyond the bone. MSCT in the bone window:
8 patients (40%) had a single¬chamber, the remaining 12 patients (60%) had a
multi-chamber volumetric formation with scalloped edges. The type of "bubbles"
was visualized in 7 patients (35%), but this was not a pathognomonic sign of
ameloblastoma. Also in our study, 3 patients (15%) had a connection with an
uncut molar, 5 (25%) had resorption of the nearest teeth. In 10 cases (50%) –
pronounced thinning of the cortical layer of the lower, in 2 patients (10%) – the
upper jaw. An osteolytic focus of low density without matrix mineralization was
also observed in 4 (20%) cases.

Conclusion.
The analysis of computed tomography data allows: 1. to state
the presence of a voluminous formation, 2. to determine its prevalence, 3. to
characterize the boundaries and shadows, 4. to control postoperative changes.
There are characteristics that make it possible to obtain information about the
stage of development of pathology, its prevalence and to choose an adequate
treatment strategy, including surgical one. Moreover, contrast-enhanced MSCT
makes it possible tovisualize focal mural nodes better accumulating contrast: it
also makes it possible to assess the relative location of bone and tumor.

POST COVID
-
19 OSTEOMYELITIS ON UPPER JAW:
DIAGNOSIS AND TREATMENT

Many patients with mild or severe COVID-19 do not make a full recovery and
have a wide range of chronic symptoms for weeks or months after infection, often of
a neurological, cognitive or psychiatric nature. The epidemiological evidence,
diagnostic criteria and pathogenesis of post-COVID-19 syndrome are reviewed.
Post covid osteomyelitis on upper jaw is a rare, life-threatening disorder that
can complicate facial infection, sinusitis, orbital cellulitis, pharyngitis, or otitis or
following traumatic injury or surgery, especially in the setting of a thrombophilic
disorder. Early recognition of cavernous sinus thrombosis which, often presents
with fever, headache, eye findings such as periorbital swelling, and ophthalmoplegia,
is critical for a good outcome. Despite modern treatment with antibiotics and
anticoagulation, the risk of long-term sequelae, such as vision, diplopia, and stroke,
remains significant. This activity examines when cavernous sinus thrombosis should
be considered, how to properly evaluate this condition and the role of the
interprofessional team in caring for patients with this condition.
