“…The proximity of the sinus oor and root apices of the maxillary teeth is of critical importance in several clinical procedures such as endodontic surgery, orthodontic treatment, and implant placement. CBCT scans, with dedicated 3D software allow the reconstruction of the image in three orthogonal planes precise morphometric measurements, and provision of accurate information for case selection, treatment planning, and avoidance of collateral damage during the surgery [17][18][19].…”

“…However, in cases with accompanying signs and symptoms regarding sinuses or need for a thorough examination of the sinuses prior to surgeries, 3D imagings are the modalities of choice [9]. In this regard, CBCT provides accurate and distortion-free images of the craniofacial bones with lower absorbed radiation dose compared with multi-slice computed tomography [17][18][19].…”

Background: The purpose of the present study is to investigate the frequency and amount of extension of the maxillary sinus to the anterior region and to evaluate the vertical distance between the maxillary sinus floor and canine apices.Methods: Cone beam computed tomographic images of 300 individuals (154 males and 146 females) over 20 years (with mean age of 35.12 ± 8.40 years) were evaluated. The subjects were categorized into three age groups (20-30, 30-40 and 40-50 years). When maxillary sinus extended to the canine area, the vertical distance between them were recorded and their relationship were classified into three types: I (> 2 mm distance), II (2 mm < distance or in-contact) and III (interlock). Results: 413 out of 600 maxillary sinuses (68.8%) were extended into the canine area or beyond. Among them, 15 maxillary sinuses pneumatized into the incisor area (2.5%). The prevalence of the maxillary sinuses extended to the anterior region of the jaw was not significantly different between genders, but it was significantly less frequent in older age group and more frequent in the left side. The mean amount of anterior extension of maxillary sinus (mm) was significantly lower in older age group. Type I was the most frequent vertical relationship between the maxillary sinuses and canine apices with no significant difference in gender, side and age groups.Conclusions: Most of the maxillary sinuses extended to the canine area. Maxillary sinus extended into incisor area with the frequency of 2.5% . The amount of extension of the maxillary sinus to the anterior region and its vertical distance with canine apices decreased in older age group.

“…CBCT provides a powerful diagnostic tool for temporal bone disorders [7,9] with a high spatial resolution and three-dimensional visualization of high-contrast structures [16,17]. A slice thickness of up to 0.125 mm is possible at an acceptable low radiation dose [18], especially in limited FOV [19]. Previous studies of volumetric measurements by various researchers using CBCT included ablation volumes of the lung, pharynx, respiratory tract, skin tumors, and bones as well as the orbit and optical canal [20][21][22][23].…”

The aim of the study was to obtain volumetric data of the components of the inner ear using three-dimensional reconstruction of high-resolution cone-beam computed tomography (CBCT) images. Two hundred three CBCT image series of the temporal bone from 118 anatomically normal patients (55 women and 63 men; mean age: 49.4 ± 20.4 years) with different suspected disorders were included in this study. Normative volumetric measurements of the inner ear, the cochlea, the semicircular canals (SSC), and the vestibule were determined using a semi-automated reconstruction method of the Workstation. Volumetric measurements were successfully completed in all 118 patients. Mean inner ear, cochlear, and vestibule volumes were statistically significantly larger in males than in females on both sides (p < 0.001). Regarding the semicircular canals, no statistically significant (p = 0.053) volume difference was found. The difference between the volumes on both sides was not significant. No correlation between the patient’s age and the volume of the compartments was seen (p > 0.05). There was no significant difference between mean bony inner ear volumes when the clinical diagnoses were compared (p > 0.05 for all clinical diagnoses and volumes). Our study concluded that three-dimensional reconstruction and assessment of the volumetric measurements of the inner ear can be obtained using high-resolution CBCT imaging.

Background The purpose of the present study is to investigate the relationship between the maxillary sinus and the canine root apices in cone beam computed tomographic images (CBCT) and to assess the amount of extension of the maxillary sinus to the anterior region of the jaw in different sexes and age groups. Methods CBCT of 300 individuals (154 males and 146 females) over 20 years (with a mean age of 35.12 ± 8.40 years) were evaluated. The subjects were categorized into three age groups (20–30, 30–40, and 40–50 years). When the maxillary sinus extended to the canine area, the vertical distance between them was measured, and their relationship was classified into three types: I (more than 2 mm distance), II (less than 2 mm distance or in-contact), and III (interlock). Results 413 out of 600 maxillary sinuses (68.8%) were extended into the canine area or beyond. Among them, 15 maxillary sinuses pneumatized into the incisor area (2.5%). The prevalence of the maxillary sinuses extended to the anterior region of the jaw was not significantly different between genders. However, it was significantly less frequent in the older age group and more frequent on the left side. In addition, the mean amount of anterior extension of the maxillary sinus (mm) was significantly lower in the older age group. Type I was the most frequent vertical relationship between the maxillary sinuses and canine apices with no significant difference in gender, side, and age groups. Conclusions In most cases, the maxillary sinus extended to the canine area and sometimes reached the incisor region. This necessitates paying more attention to the maxillary anterior sextant during surgical procedures.

Abstract: Our results suggest that CBCT images provide reliable volumetric information that can be depended on for artificial organ construction, and which may aid the guidance of the operator prior to or during the intervention.
