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.

AbstractThe maxillary sinuses of 40 patients suffering from primary atrophic rhinitis (ozaena) were studied radiologically, antroscopically and histopathologically. Sixty percent of the patients showed thick bony walls and a small cavity of the maxillary sinus on X-ray and on antroscopy. On the other hand, 25 percent of the cases revealed signs of infection including mucopurulent secretion on antroscopy associated with corresponding histopathological changes. It is concluded that poor pneumatization of the antrum plays a more important role in the pathogenesis of ozaena than infection.

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.

The National Institute of Standards and Technology (NIST) certifies a suite of Standard Reference Materials (SRMs) to address specific aspects of the performance of X-ray powder diffraction instruments. This report describes SRM 1976b, the third generation of this powder diffraction SRM. SRM 1976b consists of a sintered alumina disc, approximately 25.6 mm in diameter by 2.2 mm in thickness, intended for use in the calibration of X-ray powder diffraction equipment with respect to line position and intensity as a function of 2θ-angle. The sintered form of the SRM eliminates the effect of sample loading procedures on intensity measurements. Certified data include the lattice parameters and relative peak intensity values from 13 lines in the 2θ region between 20° and 145° using CuKα radiation. A NIST-built diffractometer, incorporating many advanced and unique design features was used to make the certification measurements.

Abstract. The mucoperiostitis and local osteitis are radiological symptoms of the fungal ball of the maxillary sinuses. The condition of the mucoperiosteum and the adjacent bone in the alveolar bay of the maxillary sinus predict the results of dental implantation and subantral augmentation. The endoscopic access to the sinus by the antrostomy in the middle meatus and infraturbinal have been used to avoid excessive tissue injury during the removal of the fungal ball. Aim: To assess the condition of the bone and mucoperiosteum of the maxillary sinus in patients with fungal ball after rhinosurgery by the antrostomy with additional osteoplastic infraturbinal access. Methods and materials: The data of 102 patients who underwent surgery for the fungal ball of the maxillary sinus were analyzed, and subsequently - subantral bone augmentation and dental implantation were performed. In patients of the first group (67 people) - endoscopic intervention was performed by antrostomy in the middle meatus, and in 2nd group (35 people) - additional osteoplastic infraturbinal access was used. Result: Computed tomography data were evaluated before endoscopic sinus surgery and before subantral augmentation. The frequency of signs and severity of osteitis according to Kannedy Osteitis Score, after the intervention did not change significantly, and was established as 0.90 ± 0.07 in patients of group №1 and 0.77 ± 0.08 – group №2. The total frequency of complications with subantral augmentation in the comparison groups was 17.91 ± 4.68% and 17.14 ± 6.37%, respectively. Symptoms of osteitis in patients with fungal ball of the maxillary sinus after endoscopic removal, in the first 4 - 6 months of observation tend to regress, but do not disappear. Conclusions: The incidence of osteitis in computed tomography in patients with maxillary sinuses fungal balls in 4.8 months after endoscopic removal tends to decrease and is 77.61 ± 5.09% when approach through the middle meatus and 74.29 ± 7, 39% in patients with combined infraturbinal approach. The use of additional infraturbinal approach in patients with a fungal ball does not adversely affect the results of subsequent subantral augmentation and dental implantation.

ABSTRACT Introduction The present study was undertaken to evaluate the anatomy of the maxillary sinus in relation to its position and the height of its septa, using cone beam computed tomography (CBCT). Materials and methods In this descriptive retrospective study, 300 CBCT images of maxillary sinuses of patients with posterior maxillary edentulism were evaluated. The maxillary sinus septa were evaluated in relation to their prevalence, height, and position; t-test and Mann–Whitney tests were used for the analysis of data. Results Sinus septa were detected in 44% of the subjects, with equal frequencies in the anterior, middle, and posterior positions. The mean height of the septa was 3.6 ± 1.56 mm. Conclusion In a population of Iranian subjects, in half of the cases, the sinus septa might be present in the anterior, middle, and posterior positions. Clinical significance In order to avoid intraoperative problems during sinus lift procedures, it is necessary to accurately evaluate the sinus, preferably with the use of CBCT.

Aim: The aim of the study was to examine the prevalence of maxillary sinus septa (MSS) in a Turkish population, using cone-beam computed tomography (CBCT).
  Methodology: The CBCT images of 350 untreated patients (178 male, 172 female ranging in age between 18 and 65) were included in this study. The presence or absence of MSS was determined in axial, sagittal, and coronal planes by considering gender and side. For statistical evaluation, a chi‐square test was used to determine any differences in the prevalence of MSS with significance set at 5%.  Results: MSSs were observed in 201 out of 700 sides (28.71%) and 141 out of 350 patients (40.28%), of which, 70 were in males and 71 in females. MSS were also observed in a higher prevalence on the bilateral side. (17.14%). Female patients showed higher prevalence (41.27%) than the male patients (39.32%). Conclusion: MSS was observed in 40.28% of examined Turkish subjects and detected more frequently in females and on the bilateral side.   How to cite this article: Laçin N, İzol BS.
