“…Considering the importance of changes in the structure of bone tissue that occur in the process of adaptive remodeling, 1 determination of X-ray density indicators in children with unilateral CLP using CT of the skull with subsequent 3D reconstruction of images 1,2,[3][4][5][6] is an important diagnostic criterion in planning surgical and orthodontic interventions. 1 The use of the Hounsfield scale (HU) 1,2,7-13 allowed to quantitatively assess the degree of morphological changes in dentognathic deformations, which are widespread among children of the younger and older age groups with unilateral CLP, [14][15][16] with changes in anatomy, architectonics, physic-mechanical and biological properties of the bone tissue on the healthy side and on the cleft side.…”

Relevance: Physico-mechanical characteristics of the bone tissue of the jaws, in particular its density, determine the efficacy of orthodontic interventions and are a determining parameter when calculating the forces acting on the tissue via orthodontic appliances. Hounsfield X-ray attenuation scale (HU) was used to quantify density during computed tomography. The aim to analyze the X-ray density of bone tissue of the upper jaw in children with congenital unilateral cleft lip and palate using the method of computed tomography of the skull. Materials and methods: The subject of the analysis were measurement data of the X-ray density of bone tissues of the upper jaw of 42 children in the areas that correspond to the maximum stress under the influence of orthodontic appliances. Results: It was clinically established that among all patients included in the study group, cases with left-sided clefts quantitatively dominate over right-sided ones. The results of measurements in the younger age group at the points of intersection of the compact plates of the floor of the maxillary sinus and the zygomatic alveolar ridge (ZAS and ZAI) indicate that the density is 16.6% higher on the healthy side than on the cleft side; 17.6% higher on the healthy side in the most concave points of the nasolabial buttress (NS and NI); and 14.9% higher on the healthy side at the junction of the compact plate of the hump of the upper jaw and the sphenoid bone (TSS and TSI). The zygomatic process of the upper jaw at the level of the zygomatic-maxillary suture (ZZS and ZZI) is the only site where the results on the healthy side and the cleft side did not show a statistically significant difference

“…Cone-beam CT helps to obtain detailed information on the skull. 8 , 9 3D-RA can support the assessment of vascular structures to evaluate shunt points and drainage routes. 10 , 11 Therefore, a fusion image of both cone-beam CT and 3D-RA can be suitable for the accurate diagnosis and treatment of intraosseous clival AVF.…”

BACKGROUND Intraosseous clival arteriovenous fistulas (AVFs), in which the shunt drains extracranially from the posterior and anterior condylar veins rather than from the cavernous sinus (CS), are rare. Targeting embolization of an intraosseous clival AVF is challenging because of its complex venous and skull base anatomy; therefore, a therapeutic strategy based on detailed preoperative radiological findings is required to achieve a favorable outcome. Here, the authors report the successful targeted embolization of an intraosseous clival AVF using an ingenious access route. OBSERVATIONS A 74-year-old woman presented with left-sided visual impairment, oculomotor nerve palsy, and right facial pain. A fusion image of three-dimensional rotational angiography and cone-beam computed tomography revealed a left CS dural AVF and a right intraosseous clival AVF. The shunt flow of the clival AVF drained extracranially from the posterior and anterior condylar veins via the intraosseous venous route. Transvenous embolization was performed by devising suboccipital, posterior condylar, and intraosseous access routes. The symptoms resolved after the bilateral AVFs were treated. LESSONS Accurate diagnosis and proper transvenous access based on detailed intraosseous and craniocervical venous information obtained from advanced imaging modalities are key to resolving intraosseous clival AVF.

“…Imaging examinations, such as CBCT and multislice CT (MSCT) can be used to quantitatively complete this analysis. Previous studies utilized CBCT, multislice CT, and micro-CT scans to assess the quality and density of different bones [9,10]. Due to exposure parameters and tissue attenuation, CBCT may be applied to measure bone quality, but not bone density when high-density materials are not in the field-of-view (FOV).…”

Introduction: Dental implants are the treatment of choice for patients, who are either partially or fully edentulous. Bone quantity and quality at the surgical site are key factors in an implant success. Objectives: To investigate the possibility of performing density measurement with Hounsfield units (HU) using cone-beam computed tomography (CBCT) in different types of materials. Material and methods:The physical densities of 3 blocks (3 × 3 × 5 cm) made of 5 different materials (pine, beech, plaster, acrylic, and wax) were calculated. A VistaVoxS 3D CBCT device was used to scan each block using the following acquisition protocol: 5 × 5 field-of-view, 98 kVp, 11 mAs, and 0.08 voxel size. The resulting 15 CBCT scans after acquisitions were imported to AIS3DAPP 5.0 software. A virtual implant (16 mm × 5.2 mm) was centered in each block's image, and bone density tool available in the software was used to measure HU with the virtual implant's thirds. For each implant, mean HU values of the most anterior, posterior, left, and right sides were measured. Results: In general, each material produced different mean HU values. Plaster produced the highest values (2,160.9), followed by acrylic (126.39), wax (-170.65), beech (-655.78), and pine (90.12). Conclusions: CBCT HU were repeatable and higher in the high-density material studied. The bone density tool demonstrated to be useful and reproducible.
