Abstract Background and aims : Measurements of the maxillary sinus volumes in computed tomography (CT) scans can be used for determination of gender when other methods are inconclusive. Maxillary sinus dimension measurements are valuable in studying sexual dimorphism and can assist in gender determination. The radiographic images can provide adequate measurements for maxillary sinuses that cannot be approached by other means. The purpose of the present study was to determine and compare the volume of the maxillary sinus between males and females of Tamil Nadu region using CT scans. Materials and methods : This study was carried out by using CT images of head region of 100 males and 100 females who underwent CT scanning for indications other than the pathology of the maxillary sinuses. The CT images obtained were of patients between 20 to 50 years of age. The maxillary sinus volume of each side were calculated by using the following formula: Maximal width X Maximal height X Maximal depth X 0.5. Comparison of data between genders and sides was done. The statistical inference was derived by applying unpaired student "t" test and the p value was obtained (p value <.05 was considered statistical significant). Results: Oncomparison of males with females, the mean volumes of maxillary sinuses on each side (left and right) had shown a statistically significant difference (p<.OOOl ). The maxillary sinus volumes of the males were found to be significantly higher than that of the females. Among males, the average mean volume of maxillary sinuses (right + left) is 15.15 ± 0.45 cm3. Among females, the average mean volume of maxillary sinuses (right + left) is 12.77 ± 1.34 em' which is significantly lesser than that of the males. Conclusion : It can be concluded that the volumes of the maxillary sinuses of males are larger than those of the females and this difference is statistically significant. Maxillary sinus dimension measurements can assist in gender determination.

Abstract Background and aims: Maxillary sinuses are the largest of the paranasal sinuses known for variability in their dimensions. The maxillary sinus dimensions can be better ascertained in living by using computed tomography instead of plain radiography. This study was planned for highlighting the variations in the dimensions of the maxillary sinuses of population of Tamil Nadu region. The aims of the present study were to estimate dimensions of the maxillary sinuses on computed tomographic (CT) scan of the head of patients from Tamil Nadu and to compare the data gender wise and sidewise. Material and methods: Maximum width, height and depth of maxillary sinus of both sides were measured in CT - head images of 100 males and 100 females of 20-50 years of age in Tamil Nadu. Comparison of data between genders and sides by applying unpaired student "t" test was done. Results : The mean depth, height and width of both right and left maxillary sinuses were comparatively less in females than the males and the difference was found to be statistically significant ( P <.0001). On comparison between the sides of maxillary sinuses, the depth and the height of maxillary sinus did not show any significant difference in the measurements (p >.05), whereas the width of the left side (23.96 mm) was higher than that of the right side (23.69) and the difference was found to be statistically significant (P<.05). The combined average maxillary sinus dimensions (in mm) for both genders in the study population of Tamil Nadu are as follows: Right side depth: 33.71 ± 1.00; Left side depth : 33.65 ± 1.22; Right side height: 34.66 ± 2.71; Left side height: 34.74± 2.48; Right side width: 23.69 ± 0.78 and Left side width: 23.96 ± 0.86. Conclusion: The dimensions of maxillary sinuses in males were found to be larger than those of females and this difference was statistically significant. The average width of the maxillary sinuses on the left side is significantly more than that of right sided sinuses. Computed tomography measurements of maxillary sinuses may be useful in gender determination.

Objective A radioanatomic study of surgically relevant variations in the greater palatine canal (GPC) on computed tomography (CT) was performed to determine susceptibility during endoscopic endonasal procedures. Study Design Blinded radioanatomic analysis. Setting Tertiary university hospital. Subjects and Methods Fifty consecutive paranasal CT scans (100 sides) were analyzed. Measurements were standardized to landmarks such as the inferior turbinate (IT) and floor of the nasal cavity (FNC) to assess variability and vulnerability of the nerve. Measurements included (1) incidence of maxillary sinus pneumatization posterior to the GPC, (2) distance from the posterior wall of the maxillary sinus to the GPC at the IT and FNC, (3) width of bone containing the GPC, (4) incidence of medial GPC dehiscence, and (5) angle of the GPC extending from the IT to FNC. Results Ninety-one percent of maxillary sinuses were pneumatized posterior to the GPC. The distance from the posterior wall of the maxillary sinus to the GPC was 2.8 ± 1.7 mm (range, –2.3 to 5.9) at the posterior attachment of the IT and 4.1 ± 3.1 mm (range, –6.3 to 11.9) at the FNC. The width of bone containing the GPC was 3.3 ± 1.3 mm (range, 1-8.9), and the medial bony GPC was dehiscent in 38% of cases. In the sagittal plane, the angle of the GPC between the IT and the FNC was 31.9 ± 6.9 degrees (range, 10.8-45). Conclusion The GPC has considerable anatomic variability relative to important surgical landmarks in endoscopic procedures. Preoperative review of CTs to assess vulnerability may prevent postoperative complications.

Purpose. Gender determination is considered to be an important step in the reconstruction of the biological profile in forensic medicine. Maxillary sinus can be used for identification of sex when other methods are indecisive. Computed tomography (CT) provides an excellent method for examining maxillary sinuses. Hence the aim of the study was to determine the accuracy of gender determination using maxillary sinus with CT. Materials and Methods. CT images were used to measure the mediolateral, superoinferior, and anteroposterior dimensions and the volume of the maxillary sinuses in 100 patients (50 males and 50 females) to determine the gender of an individual for forensic identification. Discriminative analysis was done using the values derived and the t-test for independent samples was used to compare these values in males and females. Results. The accuracy rate was found to be 84% in males and 92% in females with the mean accuracy of 88%. Conclusion. Our study concludes that gender determination can be done using measurements of maxillary sinus through CT when other methods are unavailable. The prediction rate can be increased by including volume of the maxillary sinus.

The aim of the study was to determine the range of maxillary sinus volume and linear dimensions in adults, taking into account the gender and the side of the location using cone-beam computed tomography (CBCT) images.This study used the CBCT images of 136 patients (263 maxillary sinuses), who were presented to Minsk health facilities, with dental and maxillary sinus pathologies, aged over 20 years with no history of upper jaw surgery and with the presence of upper posterior teeth (from the first premolar to the second molar inclusive). The height, depth and width of the sinus weremeasured manually on CBCT scans. The maxillary sinus volume (V) was calculated by the formula: V = height × depth × 1/3 width.The volume of the maxillary sinus was varied from 5.53 to 24.03 cm3. The mean values of the sinus width, height and depth were 27.13 ± 3.83 mm, 35.83 ± 4.36 mm, and 38.98 ± 3.38 mm respectively.Despite a high variability of the maxillary sinus volume values, we did not find a statistically significant difference between the right and left sides in both males and females. The maxillary sinus linear dimensions and volume in females were statistically significantly less than in males.

Introduction: Quantification of maxillary sinus volumes might be a complicated and annoying process, but it is beneficial for clinicians, for example, but not limited to plastic and maxillofacial reconstruction, and artificial implants rehabilitation. Its volumetry may alter by many factors and may exhibit diversity. Aim: To determine the relationship of age and gender to the volume of the maxillary sinus in normal Sudanese subjects, and to verify if there is diversity bilaterally in both sexes. Materials and Methods: A retrospective observational study was conducted in the Department of Radiology, Royal Care Hospital, Khartoum, Sudan, during the period from August 2018 to July 2019. It consisted of Computed Tomography (CT) images of adults aged more than 17 years from both genders of Sudanese subjects, who underwent a CT scan of the Paranasal Sinuses (PNS) that showed positive clinical signs and symptoms, and proved to be normal. The obtained data was statistically analysed by Statistical Package for Social Sciences (SPSS) version 21.0. A paired-sample t-test was applied to compare between the volume of the right and left maxillary sinuses. An independent t-test was used to evaluate the relations between the gender and the volume of the maxillary sinuses. Pearson’s r test used to find possible correlation between age and maxillary sinuses volume. Results: A total of 81 CT images (46 males and 35 females, aged 17-78 years) were studied. There is negative correlation between age and maxillary sinuses volume. The advancement of age seems to reduce the size of the maxillary sinuses in male and female groups (r=-0.029; p=0.9, and r=-0.313; p=0.07, respectively). Conversely, gender had no significant effects in the maxillary sinuses volume (p=0.9). The mean total volume of the maxillary sinuses in male and female was 38.70±12.12 cm3 and 38.34±11.50 cm3, respectively. When bilaterally compared there was no significant differences were found in its volume in either sex {Male (p=0.07), female (p=0.11)}. Conclusion: The combination of CT scanning with the Cavalieri principle is a direct and accurate technique that can be safely applied to estimate the volume of the maxillary sinuses. Additional large prospective studies might be required to support the findings of this study.

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 the most reliable method for measurement of maxillary sinus dimensions. This study has been carried out to check the accuracy and reliability of maxillary sinus in gender determination using morphometric parameters. Materials and method: CT images of 100 healthy adults (54 males and 46 females) were subjected to the measurements of various dimensions. T test was used to find out the significant difference between male and females. P value was calculated. The statistical analysis was performed using word excel sheet windows 2007 and SPSS software version 21.0 was used for statistical analysis. Result: Parameters were calculated on right and left maxillary sinus. Anteroposterior diameter, height and volumes on both sides were found to be more in males as compared to females and it was statistically significant. Width of the sinuses on both sides was also more in male than in female but was statistically nonsignificant. Conclusion: The results of the present study and knowledge of anatomy of maxillary sinus as seen in CT scan will help in identification of individual, sex determination and minimizing the risk during surgery

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.

ABSTRACT Objectives: To evaluate the maxillary sinus volumes in unilaterally impacted canine patients and to compare the volumetric changes that occur after the eruption of canines to the dental arch using cone beam computed tomography (CBCT). Materials and Methods: Pre- (T0) and posttreatment (T1) CBCT records of 30 patients were used to calculate maxillary sinus volumes between the impacted and erupted canine sides. The InVivoDental 5.0 program was used to measure the volume of the maxillary sinuses. The distance from impacted canine cusp tip to the target point on the palatal plane was also measured. Results: Right maxillary sinus volume was statistically significantly smaller compared to that of the left maxillary sinus when the canine was impacted on the right side at T0. According to the T1 measurements there was no significant difference between the mean volumes of the impaction side and the contralateral side. The distance from the canine tip to its target point on the palatal plane were 17.17 mm, and the distance from the tip to the target point was 15.14 mm for the left- and right-side impacted canines, respectively, and there was a significant difference between the mean amount of change of both sides of maxillary sinuses after treatment of impacted canines. Conclusions: Orthodontic treatment of impacted canines created a significant increase in maxillary sinus volume when the impacted canines were closer with respect to the maxillary sinus.
