Analyzing the width of the maxillary sinus from private practice in Bogor, Indonesia
Scientific dental journal, 2018
Background: X-ray examinations are still a frequent diagnostic tool used by doctors in Indonesia. However, there is an apparent lack of descriptive data regarding the size and location of the maxillary sinus in Indonesian people. Objective: The aim of this study is to provide descriptive data on the size and location of the maxillary sinus among patients in the city of Bogor, West Java, Indonesia. Methods: Sixty eligible subjects aged 17 to 70 years old were randomized into six groups: male and female patients between 17 and 25 years old; male and female patients between 26 and 45 years old; and male and female patients aged 46 or older. Radiographic pictures were taken using the X-mind Novus Digital Panoramic X-ray unit and data were measured using the software Digora for Windows. Results: Using an analysis of variance, we found that men have significantly larger maxillary sinus dimensions than women (79.05 mm compared to 66.33 mm). It also reveals that there are significant differences (p<0.05) between male and female groups; whereas 2 groups aged less than 46 years old are significantly different with group aged 46 years or older in both gender. Conclusion: The study demonstrates that the size and location of maxillary sinus differ significantly between men and women in Bogor and that they follow a specific trend.
Comparison of maxillary sinus on radiograph among males and females
Dental Journal (Majalah Kedokteran Gigi), 2021
Background: An obstacle in forensic odontology is an incomplete body caused by post-mortem damage. The problem can be solved by using lateral cephalometric radiographs for victim identification. Sex determination can be performed on the maxillary sinus, which is the largest among the paranasal sinuses. Purpose: This study aims to analyse the maxillary sinuses’ width and height on lateral cephalometric radiographs among male and female subjects. Methods: The study samples were 60 lateral cephalometric radiographs (30 males and 30 females) between the ages of 20 and 40, with complete permanent dentition (or third molar absence). The height and the width of maxillary sinus measurement were performed using measurement tools of EzDent-i Vatech Software. Results: The average width of the maxillary sinus on males was 40.60 ± 1.56 mm, and the height was 35.02 ± 2.09 mm, while the width and the height on females were 36.93 ± 1.30 mm and 29.72 ± 1.76 mm, respectively. The independent t-test r...
Three-dimensional evaluation of maxillary sinuses in the Turkmen population, North of Iran
Journal of The Anatomical Society of India, 2021
Background and objective: Maxillary sinus disease is frequently observed in patients with unilateral cleft lip and palate (UCLP). The anatomical variations of maxillary sinus and maxilla may play a role in the high incidence of sinusitis. The aims of this study were to evaluate and compare the three-dimensional (3D) structural features of maxillary sinus and maxilla in UCLP adolescent patients between the defect and non-defect sides, and investigate the morphological relationship between the maxillary sinus and maxilla on the defect side by using cone-beam computed tomography (CBCT). Methods: CBCT images were acquired from 42 UCLP adolescent patients. Maxillary sinus and maxilla on the defect and non-defect sides were segmented respectively and assessed three dimensionally, and the comparison was performed by paired t-test. A multiple linear regression was conducted to investigate the morphological relationship between the maxillary sinus and maxilla on the defect side. Results: No statistically significant difference was observed in any parameter of the maxillary sinus between the defect and non-defect sides (P > 0.05). Significant differences were observed in the length, anterior width, anterior height, and volume of the maxilla between the defect side and non-defect sides (P < 0.05). The parameters of maxillary sinus were significant related to the posterior width and height of maxilla on the defect side. Conclusion: Adolescent patients with UCLP present similar 3D structural features of the maxillary sinus on both sides. Significant differences of the maxilla between the defect and non-defect sides were displayed in the area adjacent to the defect but not showed in the posterior portion of maxilla. Certain structures of the posterior portion of maxilla contribute to the variability of maxillary sinus.
Morphometric Study of Maxillary Air Sinus using Computed Tomography
International Journal of Anatomy Radiology and Surgery, 2017
Introduction: Maxillary air sinus is the largest paranasal air sinus. It exhibits dimorphic features and remains intact in victims who are incinerated therefore it can be used for identification of individual and gender determination. CT is most reliable method for measurements of maxillary sinus dimensions and anatomical variations related to it. Aim: The present study was conducted to find out the volume and maximum Anteroposterior (AP) diameter of the maxillary air sinus and the anatomical variations related to it. Materials and Methods: CT images of 100 healthy adults were subjected to the measurements of volume and maximum AP diameter of right and left maxillary air sinus using Autocontour software. Student's 't'-test was used to find out significant difference between males and females. Results: The volume of right and left maxillary sinuses in males were found to be 12.95±4.48 cm3, 13.26±3.94 cm3, and in females 10.59±3.37 cm3, 10.16±2.92 cm3 respectively. A stati...

This study is an anatomical study designed to benefit surgeons working in the region of the maxillary sinus. This paper investigates ethnic and gender variations in the shape of the maxillary sinus in dried crania from the Raymond Dart collection of human skeletons. The paper claims that an estimate of the area of the medial antral wall of the maxillary sinus is one of the best ethnic/gender group predictors. Helical, multislice computed tomography was performed using 1mm coronal slices length, depth, width and volume measurements for each sinus were taken. Classification by shape and estimated area of medial wall was attempted. Shape classification was found to be unsuccessful whilst medial wall classification into ethnic/gender groupings gave encouraging results. The area of the medial wall is related to ethnic/gender groups.

Objectives; Determination of sex utilizing skeletal remains still displays a difficult issue to forensic specialists, particularly when body fragments are only found in a mass disaster, car or plane accident, fires, and even in the investigations of crimes. Sinus radiography is one of these methods that was utilized for determining the sex of a person. Consequently, the present study aimed to evaluate the reliability of the morphometric dimensions of the maxillary sinus in determining sex, and age via computed tomography (CT) scan images as paranasal sinuses still undamaged whether the skull and other bones are seriously damaged or not. Methodology; The present work involved 30 adult cases (15 males and 15 females) referred to the radiodiagnosis department of Beni-Suef university hospital. Determining the length, height, and width of the right and left maxillary sinuses was performed using a CT scan, and statistical analysis was performed. Results; there was a statistically significant (P < 0.05) difference in the width of the left maxillary sinus between females and males, while the other dimensions of the left and right maxillary sinuses showed an insignificant difference (P > 0.05). Conclusion; Dimensions of the maxillary sinuses alone cannot be used as an accurate diagnostic parameter for age and sex determination. We recommend doing such a study on a more significant number of people of the same sex, race, age, and who share the same food, habits, and environmental factors, to make this technique definite and attain standardizations for use in the field of forensic medicine.
The maxillary sinuses are largest of the paranasal sinuses and contained within the body of maxilla. After birth, the maxillary sinus enlarges with the growing maxilla, though it is only full developed following eruption of the permanent dentition. When teeth are lost, the maxilla reverts towards its infantile shape. Thus, its height diminishes and the alveolar process is reabsorbed. In the present study, anteroposterior, transverse and dimensions of maxillary air sinus of 90 subjects divided into 9 age groups were measured by CT scan. The study concluded that there was gradual increase in all three dimension from age groups 0-25 years and thereafter, a decrease in dimensions was observed.

Background: Gender determination is considered to be an important step inidentification.For gender determination, anthropometric assessment is one of the main forensic assessments. Objective: The aim of this study was to investigate whether the morphometric dimensions of the maxillary sinuses can be used for gender determination. Subjects and Methods: A total of 147 patients from the age group of 20-70 were included in the study.Out of which 85(57.8%) were males and 62(42.2%) were females, and who came for head and paranasal sinusComputed Tomography (CT) scan in the duration of one year from June 2018 to April 2019 and who had complaints of head ache and suspected sinus diseases but without any pathological radiographic findings or history of trauma and in whom the CT Scans were considered normal as per the consultant radiologists.To obtain the Multiple detector computed tomography (MDCT)images, an MDCT Siemens Somatom Definition AS 64 SLICE machine with a high-resolution bone algorithm, 233 mm field of view, 120 kV, 395 mA, scanning time of 6.5 seconds and slice thickness of 1.0 mm was used to obtain the axial images. Results: The proportion of correctly identified females with right and left sinus was 74.2 % and 77.4% while using right and left sinus 76.5% and78.8% of males were correctly identified respectively. The combined proportion of correctly identified gender was 75.5% using the right sinus and 78.2% using the left sinus. Conclusion: All the parameters were equally and statistically significant in gender determination in our study making imaging of maxillary sinus on CT scan as an important anatomical structure as an aid in forensic anthropology for criminal investigations. Based on the multiple regression analysis a formula is also derived to easily and conveniently calculate the gender based on the values of maxillary sinus obtained on CT scan.
Sexual Dimorphism of Maxillary Sinus: A Morphometric Analysis using Computed Tomography
Journal of Lumbini Medical College, 2020
Introduction: Gender determination is the important aspect of forensic science. Most of the bones used for sex determination are badly disfigured and found in incomplete state, thus bones recovered intact are used. Maxillary sinus being recovered intact can be used for gender determination by measuring maxillary sinus dimension through computed tomography (CT). The aim of this study was to assess sexual dimorphism using morphometric maxillary sinus measurements through CT scan. Methods: This analytical cross-sectional study included CT scan images of 80 patients (40 males and 40 females). Maxillary sinus mediolateral (ML), superoinferior (SI), anteroposterior (AP) linear dimensions and volume were measured. All the measured parameters were then subjected to Student’s t-test to determine mean difference between males and females and discriminative statistical analysis to determine gender. Results: The mean value of maxillary sinus length, width, height and volume in males on both rig...
