Evaluation of the Prevalence of Maxillary Sinuses Abnormalities through Spiral Computed Tomography (CT)

Introduction Maxillary sinus disease is common and numerous disorders can affect this anatomical area. Abnormalities can be classified as: non-neoplastic, neoplastic benign, and neoplastic malignant. Objective Evaluate through CT the prevalence of diseases in maxillary sinuses, using the Radiology Department's database of a hospital in São Paulo city. Methods The sample consisted of 762 facial CT scans that we divided into three groups: Group A (12–19 years old); Group B (20–49 years old); Group C (above 50 years old); and male or female. We considered the following pathological processes: I - Mucoperiosteal Thickening; II - Chronic Sinusitis; III - Chronic Odontogenic Sinusitis; IV - Rhinosinusitis; V - Polypoid Lesions; VI - Bone Lesions; VII - Neoplasms; VIII - Antrolith; IX - Foreign Bodies; X - Oroantral Fistula. Results Our study found that 305 exams (40.02%) were normal and 457 exams (59.97%) were abnormal. We found the following disease frequencies: focal mucoperiosteal thickening (21.25%); polypoid lesions (10.76%); chronic sinusitis (7.48%); chronic odontogenic sinusitis (2.29%); neoplasms (2.03%); rhinosinusitis (1.77%); bone lesions, foreign bodies and oroantral fistula in 0.65%; 0.13% and 0.06% respectively. There was no significant difference between male and female, and Groups A, B, or C when relating the frequencies of abnormalities found. There was no significant difference between male and female and the age group for the side of the altered maxillary sinus. Conclusion We observed a high prevalence of sinus maxillary diseases. Mucoperiosteal thickening; acute, chronic, and odontogenic sinusitis; polypoid lesions and neoplasms have high prevalence in maxillary sinuses. Thus, facial CT exam was effective for the evaluation of diseases in maxillary sinuses.

Abstract Introduction The endoscopic access to lesions in the anterolateral wall of the maxillary sinus is a challenging issue; therefore, the evaluation of access should be performed. Objective To assess the accessibility of three endoscopic ipsilateral endonasal corridors. Methods Three corridors were created in each of the 30 maxillary sinuses from 19 head cadavers. Accessing the anterolateral wall of the maxillary sinus was documented with a straight stereotactic navigator probe at the level of the nasal floor and of the axilla of the inferior turbinate. Results At level of the nasal floor, the prelacrimal approach, the modified endoscopic Denker approach, and the endoscopic Denker approach allowed mean radial access to the anterolateral maxillary sinus wall of 42.6 ± 7.3 (95% confidence interval [CI]: 39.9–45.3), 56.0 ± 6.1 (95%CI: 53.7–58.3), and 60.1 ± 6.2 (95%CI: 57.8–62.4), respectively. Furthermore, these approaches provided more lateral access to the maxillary sinus at the level of the axilla of the inferior turbinate, with mean radial access of 45.8 ± 6.9 (95%CI: 43.3–48.4) for the prelacrimal approach, 59.8 ± 4.7 (95% CI:58.1–61.6) for the modified endoscopic Denker approach, and 63.6 ± 5.5 (95%CI: 61.6–65.7) for the endoscopic Denker approach. The mean radial access in each corridor, either at the level of the nasal floor or the axilla of the inferior turbinate, showed a statistically significant difference in all comparison approaches (p < 0.05). Conclusions The prelacrimal approach provided a narrow radial access, which allows access to anteromedial lesions of the maxillary sinus, whereas the modified endoscopic Denker and the endoscopic Denker approaches provided more lateral radial access and improved operational feasibility on far anterolateral maxillary sinus lesions.

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.

Abstract Background: The purpose of the present study is to investigate the frequency and amount of extension of the maxillary sinus to the anterior region and to evaluate the vertical distance between the maxillary sinus floor and canine apices.Methods: Cone beam computed tomographic images of 300 individuals (154 males and 146 females) over 20 years (with mean age of 35.12 ± 8.40 years) were evaluated. The subjects were categorized into three age groups (20-30, 30-40 and 40-50 years). When maxillary sinus extended to the canine area, the vertical distance between them were recorded and their relationship were classified into three types: I (> 2 mm distance), II (2 mm < distance or in-contact) and III (interlock). Results: 413 out of 600 maxillary sinuses (68.8%) were extended into the canine area or beyond. Among them, 15 maxillary sinuses pneumatized into the incisor area (2.5%). The prevalence of the maxillary sinuses extended to the anterior region of the jaw was not significantly different between genders, but it was significantly less frequent in older age group and more frequent in the left side. The mean amount of anterior extension of maxillary sinus (mm) was significantly lower in older age group. Type I was the most frequent vertical relationship between the maxillary sinuses and canine apices with no significant difference in gender, side and age groups.Conclusions: Most of the maxillary sinuses extended to the canine area. Maxillary sinus extended into incisor area with the frequency of 2.5% . The amount of extension of the maxillary sinus to the anterior region and its vertical distance with canine apices decreased in older age group.

ABSTRACT Foreign bodies in the paranasal sinuses after critical accidents are rare occurrences that have sporadically been reported worldwide. Firearm projectiles, daggers, knives, glass fragments, stones, teeth, and wood can get lodged in the soft and hard tissues of the face. The management and prognosis in these cases depend on the composition and location of the foreign body as well as on the presence or absence of infection. Although there are reports involving the soft tissues of the face, the ethmoid, sphenoid, frontal, and maxillary sinuses are the most frequently involved sites. The main manifestation of this condition is sinusitis arising from infection and/or inflammation caused by the foreign body, which is a contaminated object. We report a case of removal of a firearm projectile located in the maxillary sinus of a 34-year-old patient under local anesthesia.

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.

Background: In forensic science, skeletal examination is often done with primary focus on identification. Complete identification is a rare event in this type of examination. However, anthropological identification can be done in skeletal examination. Skull is the second best for determination of sex next to pelvis. Maxillary sinuses are paranasal sinuses, and a feature for sexual dimorphism which remains intact in partially charred. The study of maxillary sinus is best done on Computed Tomography.Objectives: The primary objective of this study is to evaluate bilateral maxillary sinus for sexual dimorphism using Computed Tomography.Methodology: A total of 104 CT head cases were studied of which 52 were male and 52 female. The anterior posterior length, transverse width and height of bilateral maxillary sinus were measured in male and female through their DICOM images using inbuilt electronic calliper. Descriptive analysis for mean, paired t test to compare right and left maxillary sinus in both male and female, and student t test for compare male and female were used for analysing the value measured and calculated.Results: Male maxillary sinus (Right 12.76±4.62 & Left 12.39±3.81) was found be to larger than that of female (Right 12.16±4.78 & Left 11.80±4.49). Right and left maxillary sinus of both the sexes showed no significant difference when paired t test was used. Using independent t-test showed no sexual dimorphism between the two sexes.Conclusion: Maxillary sinus is not good tool for sex determination in Nepalese population. However further studies could be done on larger population sample, as smaller sample size could be the limitation of this study.

OBJECTIVE: To evaluate the relative area of the maxillary sinus in edentulous posterior maxilla with regard to linear area, bone septa and sinus pathologies. METHODS: A retrospective longitudinal study was conducted of tomographic exams in 60 individuals between 35 and 75 years of age, with the inclusion criteria being the uni- or bilateral edentulous posterior maxilla. Measurements were taken by the program in 101 maxillary sinuses. The horizontal and vertical measurements of each sinus were multiplied and resulted in a linear area in mm2. RESULTS: Of the 101 maxillary sinuses evaluated, 14 presented sinus pathologies (13.86%) and 22 (21.78%) with bone septa. The mean mesio distal distance was 38.4 mm (p ≤ 0.05), mean height 34. 5 mm (p ≤ 0.05) and mean linear area of 1335.88 mm² (p = 0.05). The Student's-t and analysis of variance (ANOVA) tests were applied for statistical analysis There were no statistically significant difference in the height and width of the edentulous maxillary sinuses between genders, but there was a variation in the linear area and the finding of the presence of bone septa and sinus pathologies. CONCLUSION: The conclusion of this study corroborates those of previous study about the need for imaging exams with the purpose of obtaining information about the dimensions of the maxillary sinus, as guidance with regard to the quantity of graft material, choice of donor region, and presence of septa. These data serve as guidance in the sinus lift technique and the presence of sinus pathologies, which involve treatment before bone graft surgeries.

During the surgical removal of maxillary molars, tooth or fragment displacement into the maxillary sinus may occur. The presence of foreign bodies inside these cavities leads to complications such as mucoceles, cellulitis, oroantral fistulae and maxillary sinusitis, to prevent the arise and worsening of complications, these events must be addressed in an early stage. This article aims to report the removal of a tooth root from the maxillary sinus, through the modified Caldwell-Luc (CLM) approach and describe the current indications for the Caldwell Luc technique. It reports an upper third molar surgery in which a patient had the distal root of the left superior third molar displaced into the maxillary sinus, later showing signs of sinus opacification and loss of patency of the maxillary ostium obstructed by the root. After antibiotic treatment, the root was recovered through the CLM technique by local anesthesia, without complications. Foreign bodies in the maxillary sinuses must be urgently addressed, avoiding the development of infectious conditions, the CLM approach is the choice approach to manage these complications by a simple and safe way.

The maxillary sinuses diseases are an actual clinical problem today. The aim of our study was to determine the frequency of pathology of the maxillary sinuses of different origin and its age dynamics in adults. 500 series of anonymized tomograms of adults were analyzed: 22-35 years (1st group) and 36-60 years (2nd group in men) and 36-55 years (2nd group in women). Cone-beam computed tomography (CT) of the nose, paranasal sinuses, and upper jaw was performed on a Point 3D Combi 500 cone-beam tomograph. RealScan software was used to analyze the test results. The results of the study showed that among the adults who applied for examination of the maxillary sinus, only 20% had no pathology. Patients of the first age group are most often diagnosed with pathological changes of the maxillary sinus, which have a rhinogenic origin. In persons of the second age group, regardless of gender, the pathology of the maxillary sinus of odontogenic origin is most often diagnosed. With age, the number of pathologies of odontogenic origin increase both in men and in women, and the number of pathologies of other origin, including rhinogenic - decreases.
