Objective: Morphometry of frontal sinuses has been studied extensively in many countries. However, these findings cannot be generalized due to genetic and environmental factors affecting the skeletal structure. The main aim of this study was to morphometrically analyze the frontal sinuses in patients who underwent non-contrast computed tomography (NCCT) skull imaging at Teaching Hospital Peradeniya and to assess its association with age and sex.
Methods: This retrospective study included 300 NCCT skull images obtained by a multi-slice computed tomography(MSCT) scanner at the Teaching Hospital Peradeniya. This age- and sex-matched sample was selected using consecutive sampling and consists of seven age groups (20-29, 30-39, 40-49, 50-59, 60-69, 70-79, and 80-89). Right and left frontal sinus values (length, height, width of each sinus, and total width) were measured using the RadiaAnt DICOM Viewer 2020.2.3 software, and age and sex were obtained from the CT images. The association among the variables was analyzed using the t-test and binary logistic regression model.
Results: In our study sample, 59% ( = 177) were male and the mean age was 57.94 years. The means of left side sinus values were larger than right sinus values, which was statistically significant. A statistically significant association was seen between frontal sinus parameters and sex; those of males were higher than that of females. No significant association between the sinus size and age was observed.
Conclusion: Morphometric analysis of frontal sinuses using NCCT images is useful for the sex differentiation of unknown bodies for medico-legal purposes. Furthermore, the mean sinus values specific to the current study population will also be helpful in ethnic differentiation.

Polybrominated diphenyl ethers (PBDEs) have been classified as a new class of persistent organic pollutants by the United Nations Environment Programs in 2009. In environment, PBDEs can undergo the degradation process to form less brominated diphenyl ethers. In the present study, the 96 h LC value for 4-bromodiphenyl ether (BDE-3) was found to be 3.

Introduction And Aims: Implantation of the posterior maxilla with insufficient bone height faces challenges. Studies have shown that the use of ultrashort implants can avoid additional damage. This finite element analysis study aimed to evaluate the impacts of different lengths of ultrashort implants and three surgical approaches on stress, strain, and displacement in the posterior maxilla with varying bone heights.

Introduction: Tissue eosinophil counts (TEC) might serve as a biomarker linking chronic rhinosinusitis (CRS) and the presence of adult-onset asthma. This study aimed to determine if TEC in sinus mucosa/polyps in CRS patients is an independent indicator of asthma and to identify its optimal cut-off point.
Methods: This cross-sectional study was conducted on primary CRS patients scheduled for surgery.

: In this study, we review the diagnostic accuracy of magnetic resonance imaging (MRI) in detecting orbital and intracranial invasion of sinonasal malignancies (SNMs) using histopathological and surgical evidence as the reference standard. : A systematic search of studies in English was conducted in MEDLINE and Embase, limited to articles published since 1990. We included studies using preoperative MRI to detect the intracranial and orbital invasion of SNMs, with histological or surgical confirmation as the reference standard, and reported patient numbers in each class as required to assess diagnostic accuracy.

: Atrial fibrillation (AF) is a common arrhythmia in the emergency department (ED). We investigated the role of N-terminal pro b-type natriuretic peptide (NT-proBNP) in predicting both the outcome of AF cardioversion and the risk of AF recurrence or persistence on the 8th (D8) and 30th (D30) day post-cardioversion. : This prospective, observational study evaluated patients with recent-onset AF, managed by either pharmacological (PC) or electrical cardioversion (EC) in the ED.
