Computed Tomographic Measurement of Maxillary Sinus Volume and Dimension in Correlation to the Age and Gender : Comparative Study among Individuals with Dentate and Edentulous Maxilla

OBJECTIVE: To evaluate change of the maxillary sinus volume according to patient age and gender by using a 3-dimensional (3-D) reconstruction of computed tomography images. STUDY DESIGN AND SETTING: One hundred seventy-three people (totaling 238 maxillary sinuses) who had undergone paranasal sinus CT scan between December 2000 and November 2003 and had no evidence of inflammation or hypoplasia in the CT finding and had no specific history of paranasal sinus surgery or maxillofacial trauma were retrospectively analyzed. The 3-D reconstruction images were obtained by using a surface-rendering technique (Vworks; CybeMed, Seoul, Korea) on a personal computer. The mean volume of maxillary sinus was evaluated according to patient chronologic age and gender. The ratio of the maximum horizontal and half-horizontal extension for the estimation of the morphological change of maxillary sinus and the degree of descent of the sinus below the nasal floor were evaluated in the 3-D image. RESULTS: The development of the maxillary sinus continued until the 3rd decade in males and until the 2nd decade in females. The mean maxillary sinus volume in early adults was 24,043 mm 3 (males) and 15,859.5 mm 3 (females). There was a significance difference in the sinus volume ( P < 0.05) according to gender, and there was a significant difference in the maxillary sinus volume according to age before it reached maximum. After its maximum growth period, however, there was no significant difference in the volume change of maxillary sinus and the descent below the nasal floor between two adjacent groups. CONCLUSIONS: The growth of the maxillary sinus continues until the 3rd decade in males and the 2nd decade in females. Therefore, a maxillary sinus operation affecting the bony structures before these ages might affect the development of the sinus and needs to be performed carefully

Perceived motor competence (PMC) is a psychological construct that may be influenced by various environmental factors. This study aimed to analyze differences in PMC of children from four diverse countries. The sample was comprised of 231 Brazilian, 129 Australian, 140 Portuguese, and 114 American children, aged 5–8 years. The PMC was assessed using the Pictorial Scale of Perceived Movement Skill Competence for Young Children. Differences in PMC among countries were verified using Kruskal-Wallis tests, separately by age and gender. For girls (from the age of six), differences were found in the leap, slide, hit, and catch, as well as the sum of object control skills and total score. For boys, differences were found among countries in the gallop, jump, slide, hit, catch, and roll, as well as the sum of locomotor and object control skills, and the total skill score. Overall, American children seem to perceive themselves more competent compared to children from other countries. Leisure and sport activities in each country may influence the construction of PMC.

Abstract Background The maxillary sinus has been considered as an important factor that affects the development of craniomaxillofacial bone. However, the correlation between the maxillary sinus and skeletal malocclusion is controversial. This study aimed to compare the dimensions of the maxillary sinus in patients with different vertical growth patterns and investigated the correlation between the maxillary sinus and craniofacial parameters.Methods This descriptive study included 90 patients from age 15 to 20 years old. According to the vertical growth patterns that were classified by MP-FH (angle between the mandibular plane and Frankfort horizontal plane), they were equally divided into three groups: high-, low- and normal-angle, and the gender ratio was 1:1. Cephalometric tracings were conducted from CBCT images, which were also used to measure the dimensions and volume of the maxillary sinus. Data were analyzed with one-way ANOVA, Pearson’s correlation coefficient, and multiple comparison LSD.Results The variables of the maxillary sinus, including the volume, length, and width, among different groups, were significant(p<0.05). The variables of mandibular body length were significantly correlated with the volume of the maxillary sinus (p<0.01), and the coefficient was 0.425.Conclusions The maxillary sinus volume, length, and width were larger in low-angle patients. The mandibular body length had a significantly positive correlation with the maxillary sinus volume.

BACKGROUND: The pandemic caused by SARS-Corona Virus-2 (COVID-19) is far from over. There has been ongoing new infections across the globe. The clinical course of the disease is varied among different individuals. The prediction of severity and mortality is very difcult but quite essential for timely escalation of the treatment. This is a comparative study of clinical, biochemical parameters among the survivors and non survivors of COVID-19 infection. METHODOLOGY: This is a retrospective study conducted in a tertiary care hospital in South India. This study was an audit of 39 survivors and 39 non survivors of COVID-19 infection. These patients were matched with age and gender. The clinical prole, Biochemical parameters and the clinical course among the two groups were compared and analyzed. RESULTS: 39 survivors and 39 non survivors were included in the study. The two groups were age and gender matched. The symptoms were fever, cough, breathlessness, fatigue, myalgia, body ache, diarrhea. Breathlessness was more common among patients who did not survive. Pneumonia severity index was class 1 and class 2 among patients who survived. PSI was class 4 and class 5 among the patients who did not survive. This difference was statistically signicant. It was seen that there were signicant number of comorbidities and inammatory markers like CRP, D DIMER, LDH, S. Ferritin seen among non survivors compared to the survivors. The study CONCLUSION: shows that presence of comorbidities has an adverse impact on the outcome of the patients with COVID-19 infection. The elevated inammatory markers like CRP, D Dimer and LDH predicted poor outcome. Pneumonia severity index was a useful marker to predict the outcome among patients of COVID.

Objective: The purposes of this study were to evaluate and compare the maxillary sinus volume (MSV) of patients with a unilateral cleft lip and palate (UCLP) between the cleft side and noncleft side and between adolescent patients with UCLP and a control (noncleft) group using cone beam computed tomography (CBCT). Methods: CBCT images of 44 UCLP patients (29 males and 15 females, with a mean [SD] age of 13.5 [5.0] years) and 44 (22 males and 22 females, with a mean [SD] age 14.9 [4.2] years) age- and sex-matched controls were evaluated in this study. Each maxillary sinus was assessed 3-dimensionally, segmented, and its volume was calculated. Results: There were no statistically significant differences between the age and gender distributions of the groups. There was a statistically significant difference in the MSVs of the cleft (10996.78±3522.89 mm3) versus the noncleft side (10382.3±3416.2 mm3; P < .05)] but no significant difference between the MSVs of the right and left sides ( P > .05). In the intergroup comparison, the mean MSVs of the UCLP patients (10701.52±3369.33 mm3) were significantly smaller than those of the control group (16054.08 ± 5293.96 mm3; P < .001). Conclusions: The MSVs of the UCLP patients showed a statistically significant decrease compared to those of the controls ( P < .001). There was also a significant difference in the MSVs of the cleft and noncleft sides of the UCLP patients ( P < .05).
