“…The examiner established the region of interest (ROI) in the CBCT multiplanar reconstructions, using the lateral, medial, superior, inferior, anterior, and posterior walls of the maxillary sinus as limits. [ 18 ] Then, the threshold range (lower threshold: − 1000; upper threshold: − 678 to − 518 for the right sinus, and − 710 to − 572 for left sinus) was set, and semiautomatic filling of the selected region was performed after placing the “seeds” along the ROI. A manual adjustment was made if there was an area that was not defined.…”

Do the dimensions of the hard palate have a relationship with the volumes of the upper airways and maxillary sinuses? A CBCT study

Background As the hard palate is a central structure of the skull, and its close relationship with the nasal cavity, oral cavity, and maxillary sinuses, it would be of interest to study if there is a relationship between this bone and other structures of the stomatognathic system. Thus, this study aimed to assess the dimensions of the hard palate and associate them with sex, and skeletal and breathing patterns. Also, to investigate if there is a relationship between these dimensions and the volumes of the upper airways and maxillary sinuses. Methods Two hundred and ninety-eight CBCT scans of patients were classified according to sex, and skeletal and breathing patterns. Then, the linear dimensions of width and height of the hard palate at the regions of the first premolars and first molars, and the volumes of the upper airways and maxillary sinuses were measured using the CS 3D Imaging and ITK-SNAP software, respectively. Data were submitted to multi-way analysis of variance and linear regression, with a significance level of 5% (α = 0.05). Results Sex and facial type influenced the hard palate dimensions (p < 0.05). Males had greater width and height of the hard palate than females (p < 0.0001). It was observed greater width for brachycephalics at the first premolars region (p = 0.0032), and greater height for dolichocephalics at the first premolars (p = 0.0154) and first molars (p = 0.0038) regions. Skeletal malocclusion and breathing pattern did not influence the measurements of the hard palate (p > 0.05). There was a significant relationship between the width and height of the hard palate at the premolar’s region and the total volume of the upper airways (p = 0.018, and p = 0.038), and between both dimensions of the hard palate at the molar’s region and the total volume of the maxillary sinuses (p < 0.0001). Conclusions The hard palate dimensions are influenced by sex and facial type, but not by skeletal malocclusion or breathing pattern. Also, there is an association between these dimensions and the volumes of the upper airways and maxillary sinuses.

INTRODUCTION: Corpse recognition is a difficult procedure. Comparison of both ante mortem and post-mortem records is essential and assists in identification of corpses. Typical methods of identification however sometimes may be inconclusive. Gender determination is an important aspect in identification of corpses. Previously skull, pelvis and the long bones have been used in gender determination. It has been reported earlier that maxillary sinus remains intact even when skull and long bones may be badly disfigured in incarnated victims.AIM: The aim of this study was to examine whether the measurements of the maxillary sinuses may possibly be used for gender determination.MATERIAL AND METHODS: Computed tomography scans of total of 50 Adults patients within the age range of 25 to 65 years from the previous dental records were taken. Sample comprised of 25 (50%) males and 25 (50%) females. The width, height and length was measured in all cases using CT images.RESULTS: Maxillary sinus exhibits anatomic variability between genders. A significant difference in the length and height of maxillary sinus was observed with respect to males and females. (p<0.005)CONCLUSION: We conclude from the present study that the height and length of maxillary sinuses together with other bones can be used for gender determination when skeleton is not available.

Segmentation procedures for the assessment of paranasal sinuses volumes

et al. 2020

View full text Add to dashboard Cite

Background The paranasal sinuses are complex anatomical structures, characterised by highly variable shape, morphology and size. With the introduction of multidetector scanners and the development of many post-processing possibilities, computed tomography became the gold standard technique to image the paranasal sinuses. Segmentation allows the extraction of metrical and shape data of these anatomical components that can be applied for diagnostic, education, surgical planning and simulation, and to plan minimally invasive interventions in otorhinolaryngology and neurosurgery. Discussion Our aim was to provide a review of the existing literature on segmentation, its types and application, and the data obtained from this procedure. The literature search was conducted on PubMed (including Medline), ScienceDirect and Google Scholar databases, using the keywords as follows: ‘paranasal sinuses’, ‘frontal sinus’, ‘maxillary sinus’, ‘sphenoid sinus’, ‘ethmoid sinus’, in all possible combinations with the keywords ‘segmentation’ and ‘volumetric analysis’. Inclusion criteria were: articles written in English, on living human subjects, on the adult population and focused on paranasal sinuses analysis. Conclusion This article provides an overview of the types and main application of segmentation procedures on paranasal sinuses, and the results provided by the studies on this topic.

Development and validation of a formula based on maxillary sinus measurements as a tool for sex estimation: a cone beam computed tomography study

Abstract: The formula developed through measurements in the maxillary sinus using CBCT scans showed an accuracy of 84% for sex estimation and can be applied as a complementary method for human identification in the Brazilian population.
