Objectives: This study observed whether changes in diagnosis caused by analysis of three-dimensional images can lead to alterations in the treatment plans of impacted lower third molars (ILTMs). Methods: Sets of panoramic (PAN) – cone beam computed tomography (CBCT) of 218 patients were assessed for ILTM classification, contact with mandibular canal, contact and resorption of the lower second molar (LSM), intraoperative planning and post-operative expectations. Results: Percentage agreement and McNemar test compared PAN vs CBCT assessments. Logistic regression analyzed the dependency of change in surgical planning considering the changes in diagnostic features; descriptive statistics was used to observe the expectation of post-operative complications and paresthesia. Differences were found between PAN vs CBCT for classification of impaction and positioning, LSM relationship, choice for crown and root sectioning and expectation of post-operative complications (all with p < 0.001). Logistic regression indicated that the change in diagnosis caused by CBCT examination did not change the clinical decision to extract ILTM but altered the planning of intraoperative steps such as osteotomy, crown sectioning and relaxing incision. The expectation of post-operative complications decreased when professionals planned the ILTM removal using tri-dimensional images. Conclusions: We concluded that changes in the diagnosis after CBCT examination can lead to alterations in the treatment plan of impacted lower third molar.

Objective: We report a rare case of an intralingual ranula. The differential diagnosis, etiology, diagnostic features, and management are discussed. Case Report: An 18-year-old man presented with a mass that extended along the ventral surface of the tongue and up to the tip. The computed tomography scan clearly defined the extent of a cystic lesion. The pathologic diagnosis of an intralingual ranula was made. Conclusion: Lingual cysts have a varied etiology. Diagnosis hinges on histological examination of the cyst wall. Conservative resection and histological examination is the standard of care.

The introduction of new digital technologies into clinical practice and the improvement of X-ray equipment made it possible to widely use the method of cone-beam computed tomography and other X-ray methods of research. However, it is necessary to improve diagnostic methods by combining different research methods. Aim. Improvement of the method of investigation of the spatial arrangement of elements of the temporomandibular joint and medial incisors of the upper and lower jaw. Materials and methods. The study analyzed teleroentgenogram in the lateral projection and computed tomography of 292 people with no signs of organic pathology of the maxillofacial region. Generally accepted in orthodontics morphological points and anatomical landmarks were used. Results. The proposed method of combining computer tomography mandibular joint and medial cuts antagonists with teleroentgenograms of the head in lateral projection. The main reference points were the C points at the top of the articular process and the auditory passage of tomograms, which were combined with respect to the craniocerebral horizontal. When applying tomograms cutters guidance was conditional median vertical cutters, which were combined with lines forming mezhrassovyy angle teleroentgenogram, as well as the front vertical face (N – Pg), and the period Pg. Conclusion. The study proposed matching algorithm telerentgenogram and some portions of the tomograms of the temporomandibular joints and the medial incisors in the occlusal relationship.

AbstractSinusoidal obstruction syndrome (SOS) is a rare liver disorder due to hepatic vascular injury. Its rapid and accurate diagnosis is crucial for patient survival. SOS is often established clinically, based on Baltimore, modified Seattle, or European Society for Blood and Marrow Transplantation (EBMT) criteria. Unfortunately, such criteria are not highly specificity and fail to provide a timely, reliable differential diagnosis. The use of noninvasive imaging techniques, such as ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI), and fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT), has recently grown in this setting, some key imaging features offering diagnostic improvement. This review provides a synopsis of current noninvasive imaging techniques used for this purpose, summarizing accurate and reliable diagnostic features of SOS.
