BMC Med Res Methodol 2024; 24:50. [PMID: 38413856 PMCID: PMC10898185 DOI: 10.1186/s12874-024-02183-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Accepted: 02/18/2024] [Indexed: 02/29/2024] Open
Abstract
INTRODUCTION The determination of identity factors such as age and sex has gained significance in both criminal and civil cases. Paranasal sinuses like frontal and maxillary sinuses, are resistant to trauma and can aid profiling. We developed a deep learning (DL) model optimized by an evolutionary algorithm (genetic algorithm/GA) to determine sex and age using paranasal sinus parameters based on cone-beam computed tomography (CBCT). METHODS Two hundred and forty CBCT images (including 129 females and 111 males, aged 18-52) were included in this study. CBCT images were captured using the Newtom3G device with specific exposure parameters. These images were then analyzed in ITK-SNAP 3.6.0 beta software to extract four paranasal sinus parameters: height, width, length, and volume for both the frontal and maxillary sinuses. A hybrid model, Genetic Algorithm-Deep Neural Network (GADNN), was proposed for feature selection and classification. Traditional statistical methods and machine learning models, including logistic regression (LR), random forest (RF), multilayer perceptron neural network (MLP), and deep learning (DL) were evaluated for their performance. The synthetic minority oversampling technique was used to deal with the unbalanced data. RESULTS GADNN showed superior accuracy in both sex determination (accuracy of 86%) and age determination (accuracy of 68%), outperforming other models. Also, DL and RF were the second and third superior methods in sex determination (accuracy of 78% and 71% respectively) and age determination (accuracy of 92% and 57%). CONCLUSIONS The study introduces a novel approach combining DL and GA to enhance sex determination and age determination accuracy. The potential of DL in forensic dentistry is highlighted, demonstrating its efficiency in improving accuracy for sex determination and age determination. The study contributes to the burgeoning field of DL in dentistry and forensic sciences.

Three-dimensional evaluation of the maxillary sinus in patients with different skeletal classes and cranio-maxillary relationships assessed with cone beam computed tomography. Sci Rep 2023; 13:2098. [PMID: 36747077 PMCID: PMC9902527 DOI: 10.1038/s41598-023-29391-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Accepted: 02/03/2023] [Indexed: 02/08/2023] Open
Abstract
The objective was to evaluate the relationship between the dimensions of the maxillary sinuses (MSs) and various cephalometric parameters. MS volume (MSV), MS surface (MSS), linear maximum depth (LMD), linear maximum width (LMW), and linear maximum height (LMH) were calculated on CBCT scans of 99 adults. Two sets of two-way (ANOVA) assessed the influence respectively of ANB and SNA angles and of the gender on MS dimensions. Pearson's correlation was calculated between MS dimensions and different cephalometric variables. Reliability and accuracy of the proposed method was tested with intra-operator and inter-operator intraclass correlation coefficient (ICC). Two-way ANOVA showed no statistically significant difference in MSV, MSS and LMH between ANB groups, whilst males were associated with bigger sinuses. LMW showed statistically significant difference in both ANB and gender groups. LMD showed no statistically significant difference. The second Two-way ANOVA showed significantly larger MSV, MSS and LMD in patients with increased or reduced SNA angle but not between genders. LMW and LMH also showed a significant difference between genders. All linear measurements showed a significant interaction of the two factors. The intra-observer and inter-observer ICC scored high for all the tested measurements. MSV and MSS showed a positive correlation with S-N, PNS-A, S-Go, N-Me, N-Ans and the distance between Mx points. LMW had a negative correlation with Ba-S-N angle and N-Me, LMH with Ba-S-N angle, S-Go and Mx r-Mx l and LMD with N-Me and N-ANS. LMW had a positive correlation with Mx r-Mx l, LMH with S-N, S-N^Ans-Pns, N-Me, N-Ans and LMD with S-N, Ba-S-N, PNS-A, S-Go and distance between Mx points. In conclusion, MSV and MSS did not differ between the three skeletal classes, males showed significantly larger MS than in females. Concerning the influence of the cranio-maxillary relationship (SNA) and gender on MS dimension, subjects with a retrusion (SNA < 80°) or protusion (SNA > 84°) of the maxillary alveolar bone had larger MSV, MSS, LMW, LMH and LMD than subjects with a normal cranio-maxillary relationship (SNA 82 ± 2°). A statistically significant high positive correlation was observed between S-N, Pns-A, S-Go, Mx-R/Mx-r and MS dimension. Further studies that evaluate similar outcomes in different races may be able to enrich our knowledge on this topic.

A systematic review and meta-analysis. JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2023; 124:101310. [PMID: 36261062 DOI: 10.1016/j.jormas.2022.10.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 10/02/2022] [Accepted: 10/14/2022] [Indexed: 12/13/2022]
Abstract
PURPOSE This systematic review and meta-analysis aimed to investigate anatomical changes in the maxillary sinus after LeFort I osteotomy. METHODS The study protocol was developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols, and it was registered with the International Prospective Register of Systematic Reviews under registration number CRD42021236412. RESULTS Our search strategy yielded 64 articles. Of these, 31 were duplicate studies, and 33 were independently reviewed by two authors for eligibility. Of these 33 studies, 24 were excluded as they did not meet the inclusion criteria. Finally, nine studies met the criteria for inclusion, and they were critically reviewed. CONCLUSION This systematic review and meta-analysis revealed that maxillary sinus volume decreases after one-piece and multisegment osteotomies in both skeletal class II and class III male and female patients, with one-piece LeFort I osteotomy technique showing a greater reduction in the sinus volume than the multisegment osteotomy technique. The maxillary sinus thickness remained constant postoperatively.

Abstract
AIM To compare the maxillary sinus volume (MSV) of posterior cross bite (PCB) patients before and after rapid maxillary expansion (RME) by cone-beam computed tomography (CBCT). METHODS A total of 24 patients' CBCT scans that underwent RME therapy for their orthodontic treatment were used. CBCTs were obtained before (T1), immediately after (T2), and 6 months after (T3) RME. MSVs were calculated by using the 3D module of Dolphin 11.0 software. Repeated measures ANOVA (RMANOVA) was used to identify the MSV differences. RESULTS The results showed no significant differences between the right and left MSVs of the T1 group (p>.05). No significant differences were found between the right and left side MSV of the T2 group (p>.05). There were no significant differences between the right and left side MSV of the T3 group (p>.05). According to the intergroup comparisons, the RMANOVA test results revealed statistically significant right (F = 459.37, p<.001), left (F = 409.34, p<.001), and mean (F = 489.33, p<.001) MSV differences between groups. Multiple comparisons of the right, left, and mean MSV between the T1 and T2, T2 and T3, and T1 and T3 groups with Bonferroni's test revealed no significant differences between the T1 and T2 (p>.05) and T2 and T3 (p>.05) groups. However, significant differences were found in the right (p<.05), left (p<.05), and mean (p<.05) MSV between the T1 and T3 groups. The right, left, and mean MSV of the T3 group were significantly higher than those of the T1 group. CONCLUSION No significant change was detected in the MSV immediately after RME. However, MSV was significantly increased at the end of the retention period.

Abstract
AIM To assess the relations between the divergence angle of the maxillary molar roots and their proximity to the maxillary sinus floor using CBCT. METHOD This study comprised CBCT scans of the maxilla, including at least the inferior one-third of the maxillary sinus and at least one molar present in any quadrant with complete eruption and root formation. Evaluation included the vertical relations between the maxillary molar root apices and the maxillary sinus floor (MSF), and the root divergence was measured from the root apices to the floor of the pulp chamber. The chi-square test was used for the associations between the study parameters. For the correlation between root divergence angles and MSF vertical relationship types, the Spearman test was used. A P-value < 0.05 was considered significant. RESULTS A total of 100 scans were analyzed, including 316 permanent maxillary first and second molars. The MSF Type II vertical relationship was the most prevalent (39.6%), followed by Type I (31.3%). The highest divergence angle was found between the distobuccal and palatal roots (mean = 44.9 ± 10.5°). For the mesiobuccal-distobuccal angle groups, there were higher percentages of the MSF Type I and II relationships among the angle groups < 1° and 21-45°. For the mesiobuccal-palatal angle groups, a higher prevalence of the MSF Type II relationship was found in the <21⁰ and >45⁰ angle groups, and a higher prevalence of the Type I relationship was found in the 21-45⁰ angle group. For the distobuccal-palatal angle groups, higher percentages of the MSF Type II relationship were found in the three angle groups. For all teeth, there was a significant positive correlation between the MSF vertical relationship and the mesiobuccal-palatal angle (r = 0.116; P = 0.039). CONCLUSION There was a positive correlation between the divergence angle of the roots and their vertical relationship with the MSF. Clinicians should assess the divergence between the roots before performing extraction or endodontic treatments.

Abstract
OBJECTIVE To evaluate, by means of cone beam computed tomography (CBCT), the volume change of maxillary sinuses in patients that underwent orthodontic maxillary posterior en masse intrusion anchored with miniplates. MATERIALS AND METHODS The sample consisted of pretreatment (T1) and posttreatment (T2) CBCT scans obtained from 14 patients (4 male and 10 female), with a mean age of 32.4 years, that underwent orthodontic maxillary posterior en masse intrusion anchored with miniplates in the zygomatic crest. The mean treatment duration was 20 months and the mean intrusion movement was 2.4 mm. Maxillary sinus volume was measured by means of the software ITK SNAP (version 3.8.0) in T1 and T2 CBCT scans. The changes in sinuses volume were calculated by T1-T2 values. Data were analyzed statistically with Wilcoxon test at 5% of level of significance and the method error was analyzed with Wilcoxon test, intraclass correlation and Dahlberg's formula. RESULTS The mean difference (T1-T2) was -242.85 mm³ (p = 0.396) for the right sinus and -32.5 mm³ (p = 0.875) for the left sinus. A slight increase in the volume of the sinuses was shown although these results were not statistically significant. CONCLUSION The orthodontic maxillary posterior en masse intrusion anchored with miniplates did not influence significantly the maxillary sinus volume.

Abstract
OBJECTIVES The purpose of present study is to assess the maxillary sinuses patients with COPD morphometrically and volumetrically using cone-beam computed tomography (CBCT) images and compared these findings according to in age and gender of control groups. METHODS CBCT images of 80 individuals that exist from 40 patients with COPD and 40 healthy individuals (6 females, 34 males) in the tomography archive were retrospectively analyzed. The volume and surface area of maxillary sinuses in COPD and control group were measured by semi-automatic segmentation method and obtained findings were statistically examinated according to age, gender. RESULTS The study was observed that there was no statistically significant difference between the right maxillary sinus area and the groups, but left maxillary sinus and total sinus area of COPD group were observed to be significantly lower than the control group (p < 0.05). Maxillary sinus volume was found to be statistically significantly lower in patients with COPD than in healthy controls (p < 0.05). CONCLUSIONS CBCT is a practical and effective imaging method for the evaluation of maxillary sinuses. It is thought that inflammatory diseases that cause sinonasal changes such as COPD may affect maxillary sinus sizes.

Abstract
INTRODUCTION Structural or anatomic differences may arise during the development of the maxillary sinus and the process of fusion of the palate in the presence of cleft lip and palate. The present study aimed to compare the maxillary sinus volume of patients with unilateral cleft lip and palate and a control group (noncleft patients). METHODS In this retrospective case-control study, 160 cone-beam computed tomography images of 80 unilateral cleft lip and palate patients (41 males and 39 females; mean age, 12.7 ± 6.03 years) and 80 control patients (43 males and 37 females; mean age, 13.1 ± 6.27 years) were evaluated through the ITK-SNAP software (Cognitica, Philadelphia, Pa) to access the maxillary sinus volume. Analysis of covariance and regression analysis were used to assess the differences between the groups while considering the relationship between maxillary sinus volume, age, and sex. RESULTS No statistically significant differences were found in the maxillary sinus volume analyzing a unilateral cleft lip and palate and a control group (P = 0.677). Considering the cleft group, there is a tendency for the maxillary sinus volume of the cleft side to be smaller than its contralateral (P < 0.001). Statistically significant differences were found in the maxillary sinus volume, regarding the age and sex of cleft and noncleft patients (P < 0.001 for age; P = 0.001 for sex). CONCLUSIONS According to these results, the presence of unilateral cleft lip and palate did not affect the maxillary sinus volume, comparing cleft and noncleft patients. A biphasic growth pattern of the maxillary sinus and a presence of sexual dimorphism were found.

Abstract
Background: Paranasal sinus pneumatization is a complex process, and numerous computed tomography (CT) studies document developmental variations in the setting of underlying sinus disease. The purpose of this study was to investigate variation in paranasal sinus pneumatization in a population of nondiseased subjects using a metric validated for tracking individual anatomic variants as well as total sinus volume. Methods: A total of 591 consecutive sinus and maxillofacial CT scans were considered for study inclusion. After patients with inflammatory sinus or respiratory disease were excluded, 323 CT scans were scored using the Assessment of Pneumatization of the Paranasal Sinuses (APPS) instrument, and relevant demographic data were recorded for each scan. APPS findings were compared according to demographic characteristics and laterality. Results: Laterality and sex were associated with differences in paranasal sinus pneumatization in a nondiseased population. Based on APPS score, the left side (4.95) was more pneumatized than the right (4.74, P=0.006), and males (10.16) were more extensively pneumatized than females (9.18, P=0.005). We found no correlation of age with sinus pneumatization (ρ=0.025). The probability of perceptible asymmetry in any given individual's paranasal sinus pneumatization was 69%, and the probability of left-sided dominance was 53%. Conclusion: Substantial anatomic variation exists in paranasal sinus anatomy, even among patients without sinus disease. Significant differences are found between males and females and between the left and right sides. Continued systematic research of paranasal sinus anatomy may facilitate a standard for CT sinus assessment that will aid clinician evaluation of anatomic variation and surgical decision making.

Abstract
OBJECTIVES Atrophic resorption of the maxillary alveolar ridge is a complication that makes implantological rehabilitation critical. Our aim was to develop a novel computer aided procedure for the accurate quantitative assessment of maxillary residual ridge resorption including pneumatisation of the maxillary sinus that goes beyond previously described approaches and to apply it to a large dataset. MATERIALS AND METHODS To develop and refine the method, we performed a retrospective analysis using computed tomography data from 405 patients to generate segmented, three-dimensional models of zygomaticomaxillary bones and maxillary sinuses. Using anatomical landmarks and orientation lines or planes, all models were aligned automatically to subsequently generate cross-sectional images (n = 2835), enabling the classification of atrophy as well as the quantification of volumes and caudal extensions of the maxillary sinuses. RESULTS We developed and implemented an accurate and reproducible workflow for the semi-automated analysis of volumetric maxillary images. Comprehensive statistical analysis of the large quantitative dataset revealed various correlations of maxillary process heights and sinus volumes with atrophy class, age and region and identified conjectural trends over the patient group. CONCLUSIONS The method was used successfully to process a large dataset to classify atrophy, to measure alveolar height parameters, and to quantify maxillary sinus volume, bottom volume and pneumatisation. CLINICAL RELEVANCE Apart from the anthropometric value of the generated dataset, the method could be applied to provide additional and more accurate data to assess the necessity of bone augmentation in the context of three-dimensional planning before implantation.

Three-Dimensional Evaluation of Maxillary Sinus Changes in Growing Subjects: A Retrospective Cross-Sectional Study. MATERIALS 2020; 13:ma13041007.

Abstract
This study aims to evaluate changes of maxillary sinuses in growing subjects. Cone Beam Computed Tomography (CBCT) scans of 146 patients were divided according to gender and age (6–8, 9–11, 12–14 years old). Left, right and total maxillary sinus volume (MSV-R, MSV-L, MSV-Tot) and surface (MSS-R, MSS-L, MSS-Tot), left and right linear maximum width (LMW-L, LMW-R), depth (LMD-R, LMD-L) and height (LMH-R, LMH-R) were calculated using Mimics Research 22. Kruskal–Wallis Test and showed a statistically significant increase in both genders for all variables. Pairwise comparisons in females are always statistically significant in: LMH-R, LMH-R, MSS-Tot, MSV-Tot. All other variables showed a statistical significant increase between 9–11 and 12–14, and between 6–8 and 12–14 age groups, apart from LMSW-R, LMSW-L, LMSD-R, LMSD-L between 6–8 and 12–14 age groups. Pairwise comparisons in males are always and only statistically significant between 9–11 and 12–14, and between 6–8 and 12–14 groups. Symmetrical measurements (right and left) evaluated using Wilcoxon test retrieved no statistical significant difference. Comparisons between measurements on male and female subjects using Mann–Whitney test showed a statistical significant difference in 6–8 years group in MSV-R, MSV-L and MSV-Tot, and in 12–14 age group in MSV-R, MSV-L, MSV-Tot, MSS-r, MSS-l, MSS-Tot, MSW-R, MSW-L, MSD-R, MSD-L. Intraclass Correlation Coefficient (ICC) assessing inter-operator and intra-operator concordance retrieved excellent results for all variables. It appears that maxillary sinus growth resembles the differential peak of growth in male and female subjects. Sinuses starts to develop early in female subjects. However, in the first and last age group female sinuses are statistically significantly smaller compared to male ones. In male subjects, sinus growth occurs mainly between the second and third age group whilst in female subjects it starts between the first and second age group and continues between the second and the last. Sinus has a vertical development during the peak of growth, which is the main reason for its increase in volume.

Abstract
BACKGROUND The intranasal endoscopic prelacrimal recess approach (PLRA) to the maxillary sinus (MS) has been reported to treat many MS and skull base diseases. However, previous studies revealed that the width of the prelacrimal recess (PLR) shows a large individual variation. The purpose of this study was to ascertain the prevalence of the PLR in MS according to gender and age. METHODS A series of 701 maxillofacial cone beam computed tomography (CBCT) scans from adult patients were analyzed retrospectively. Patients were divided into five age groups (18-24 years, 25-34 years, 35-44 years, 45-54 years, and ≥ 55 years) and by sex. The frequencies of occurrence of the PLR in the MS were calculated and compared. RESULTS According to the findings obtained from our study, PLR was present in 81.5% of maxillary sinuses. No differences were found when the data distributions of right and left sides were compared. For individuals, the right and left sides were not always symmetrical. The probability of PLR was lesser among women than among men, but this differences was not significant. Another finding of our study was that the percentage of PLR decreased with increasing age among patients aged < 55 years, however, increased again among patients aged ≥ 55 years. CONCLUSION The anatomy of PLR varies among individuals. Careful analysis of individual anatomical structure characteristic is recommended when considering intranasal endoscopic PLRA to the MS. Besides, the age variation of PLR should be considered in order to avoid complications.

Abstract
OBJECTIVES Among children with β-thalassaemia, skeletal changes and abnormalities, such as decreased volume or obliteration of the sinus, result primarily from hypertrophy and expansion of the erythroid marrow due to ineffective erythropoiesis. This study evaluated the volumes and surface areas of the maxillary sinuses of children with β-thalassaemia using cone beam computed tomography (CBCT), and compared these findings with corresponding measurements in age- and sex-matched control children. METHODS CBCT images were retrospectively evaluated for 16 children with β-thalassaemia, 19 children with a class I skeletal pattern (class I group), and 18 children with a class II skeletal pattern (class II group). After three-dimensional analyses and segmentation of each maxillary sinus, the volumes and surface areas were calculated. RESULTS The volumes and surface areas of the right (p > 0.05 and p > 0.05) and left maxillary sinuses (p > 0.05 and p > 0.05) and SNA angles (p > 0.05) were not significantly different among the groups. The ANB (p < 0.05) and SNGoMe (p < 0.05) angles were significantly greater and the SNB (p < 0.05) angle was significantly smaller in the class II and thalassaemia groups than in the class I group. CONCLUSION Children with thalassaemia tended to have lower maxillary sinus volumes and surface areas on both right and left sides, compared to those of children with class I and class II skeletal patterns; however, these differences were not statistically significant. In children with thalassaemia, a large intermaxillary discrepancy (ANB) indicated a tendency toward the class II skeletal pattern.

Abstract
AIM Sinus maxillaris is an important anatomical formation in many branches of dentistry due to its proximity to the field of work. Various methods have been used in literature to measure the maxillary sinus volume (MSV) such as cadavers, stereology, two-dimensional conventional radiographs, computed tomography (CT), magnetic resonance imaging (MRI). The aim of this study is to evaluate the change of maxillary sinus volume according to age and gender with MIMICS 19.0 (Materialise HQ Technologielaan, Leuven, Belgium) which is one of three-dimensional modeling software. MATERIALS AND METHODS This study was performed in 200 patients selected by a retrospective review of the archives of the Dicle University, Faculty of Dentistry, Department of Oral and Maxillofacial Radiology. Patients were divided into five age groups (18-24 years, 25-34 years, 35-44 years, 45-54 years, and ≥ 55 years) and by sex. Cone-beam computed tomography (CBCT) images of the patients were transferred to the MIMICS software and the MSV was measured. All statistical analyses were performed using the SPSS (Statistical Package for Social Sciences, version 21) software. RESULTS There was no statistically significant difference between the right and left maxillary sinus volume according to the findings obtained from our study, and maxillary sinus volume in males was found to be significantly higher than that of females. Another finding of our study is that the maxillary sinus volume decreases with age increase. Especially it was also found that the sinus volume in males in the 18-24 age group was statistically significantly higher than females. CONCLUSION Consequently, maxillary sinus volume measurements can be made on CT, CBCT, MRI scans using reconstruction software.

Abstract
This is a prospective observational cross sectional study comprising of 57 patients who were having symptoms of chronic rhinosinusitis which were evaluated with the help of computed tomography scan (coronal and axial sections) to measure the thickness of all walls of maxillary sinus and it's volume. Computed tomographic imaging of sinonasal region has become the gold standard in the evaluation of patients with chronic sinusitis. The maxillary sinus is pyramidal in shape with lateral wall of nose forming its base and its apex is directed towards zygomatic process. All three dimensions of the maxillary sinus were measured and the volume of each maxillary sinus was also calculated. Hyperostosis of maxillary sinus tended to increase maxillary sinus walls thickness which ultimately results into decrease in maxillary sinus volume in chronic rhinosinusitis patients.

Abstract
OBJECTIVES The aim of this retrospective study was to investigate the correlations of maxillary sinus volume with nasal septal deviation, concha bullosa, impacted teeth, and missing teeth in the maxillary posterior region on maxillary sinus volume using cone-beam computed tomography (CBCT) images. METHODS The study cohort comprised 252 CBCT images of 252 patients retrospectively selected from the records in our CBCT archive. All CBCT images were exported to 3D modeling software for calculation of maxillary sinus volumes. Nasal septal deviation cases were grouped as mild, moderate, and severe. Concha bullosa was classified as lamellar, bulbous, and extensive. Maxillary sinus volume differences were evaluated by comparing the bilateral sinus volumes in patients with nasal septal deviation, unilateral concha bullosa, and unilateral impacted or missing maxillary posterior teeth. RESULTS The findings revealed that males had a significantly higher mean sinus volume than females (p < 0.01) and that sinus volume tended to decrease with age (p < 0.05). In moderate and severe nasal septal deviation cases, the maxillary sinus volume was significantly smaller on the same side as the deviation than on the contralateral side (p < 0.05). There were no significant correlations between maxillary sinus volume and concha bullosa, unilateral impacted teeth, or unilateral missing teeth (p > 0.05). CONCLUSIONS The present findings suggest that maxillary sinus volume is smaller on the same side as the deviation in moderate and severe septal deviation cases and that the maxillary sinus volume tends to decrease with increasing age.

Abstract
Objective To investigate the effect of hard palate angulation caused by septal deviation on the volume of the maxillary sinus. Methods Coronal computed tomographic (CT) scans of 1568 patients aged from 18 to 60 were examined. CT scans of 402 patients were included in the study. On these scans, the maxillary sinus volume, the angle of the nasal septal deviation, and the angulation of the hard palate were calculated using the ImageJ software. Each maxillary sinus volume was statistically compared with each other and with those in the control group. Correlations between palatal angulation and septal deviation were determined. Results Deviated nasal septum whether with or without deflection of the hard palate was noted to have caused changes in the volume of the maxillary sinus in both female and male patients. The volume of the maxillary sinus on the deviated side was less than that of the opposite side, and the differences between the volumes of both sinuses were statistically significant (p<0.05). No significant differences were noted when compared with the control group. A positive correlation was observed between the nasal septal deviation angle and the angulation of the hard palate. Conclusion Regardless of whether or not it affects the hard palate, nasal septal deviation reduces the volume of the maxillary sinus on the deviated side but does not affect the total volume of the maxillary sinuses. Significant differences between the volumes on the two sides can lead to facial asymmetry.

Abstract
OBJECTIVE The present study aimed to determine the structure and morphology of the maxilla in patients with cleft lip and palate to ensure safe Le Fort I osteotomy. PATIENTS A total of 34 sides of 17 patients with unilateral cleft lip and palate (nonsyndromic cases) were included in this study. The control group included 10 sides of 5 patients who exhibited skeletal mandibular protrusion without malformation. METHODS Finite element analysis was performed to examine the distribution of occlusal force over the maxilla, and continuous 3-dimensional measurement was performed at the sites of stress concentration. RESULTS In patients with cleft lip and palate, bones at the lateral border of the piriform aperture and the anterior wall of the maxillary sinus were significantly thicker than those in controls ( P < .05). Furthermore, the attachment of the pterygomaxillary junction was wider and thicker ( P < .05), and the anterior distance to the descending palatine artery was shorter ( P < .01) in patients with cleft lip and palate than in controls. Our results further indicated that alveolar bone grafting may significantly influence bone thickness and the attachment state of the pterygomaxillary junction. CONCLUSIONS Our results suggest that the complications of LFI can be reduced in patients with cleft lip and palate by ensuring proper understanding of each patient's maxillary anatomy and bone thickness, as well as the location of the descending palatine artery and the attachment state of the pterygomaxillary junction.

Abstract
Volume measurements of maxillary sinus may be useful to identify diseases affecting paranasal sinuses. However, literature shows a lack of consensus in studies measuring the volume. This may be attributable to different computed tomography data acquisition techniques, segmentation methods, focuses of investigation, among other reasons. Furthermore, methods for volumetrically quantifying the maxillary sinus are commonly manual or semiautomated, which require substantial user expertise and are time-consuming. The purpose of the present study was to develop an automated tool for quantifying the total and air-free volume of the maxillary sinus based on computed tomography images. The quantification tool seeks to standardize maxillary sinus volume measurements, thus allowing better comparisons and determinations of factors that influence maxillary sinus size. The automated tool utilized image processing techniques (watershed, threshold, and morphological operators). The maxillary sinus volume was quantified in 30 patients. To evaluate the accuracy of the automated tool, the results were compared with manual segmentation that was performed by an experienced radiologist using a standard procedure. The mean percent differences between the automated and manual methods were 7.19% ± 5.83% and 6.93% ± 4.29% for total and air-free maxillary sinus volume, respectively. Linear regression and Bland-Altman statistics showed good agreement and low dispersion between both methods. The present automated tool for maxillary sinus volume assessment was rapid, reliable, robust, accurate, and reproducible and may be applied in clinical practice. The tool may be used to standardize measurements of maxillary volume. Such standardization is extremely important for allowing comparisons between studies, providing a better understanding of the role of the maxillary sinus, and determining the factors that influence maxillary sinus size under normal and pathological conditions.

Abstract
Allergic rhinitis (AR) is associated with various developmental issues that affecting dentition. We aimed to determine whether AR is associated with an increased risk of traumatic dental injuries (TDIs) in Taiwanese individuals. We used the Taiwan National Health Insurance Research Database (NHIRD) to conduct a nested case-control study. We compared an AR cohort with a matched cohort of patients without AR. New TDI cases were determined during our study period. To compare TDI risk between our study cohorts, we used Cox proportional regression analysis, and hazard ratios (HR) with 95% confidence intervals (CI) were calculated to quantify the association between AR exposure and TDI risk. In total, 76749 patients with AR (31715 male; 45034 female) were identified. In the AR and the non-AR cohorts, 312 patients in total had TDI. Patients with AR had a significantly higher risk of TDI than those without AR (aHR = 1.92; 95% CI = 1.459-2.525; P < 0.001). The risk of TDI was markedly higher in the AR cohort, except in the 3-12-year-old group, and with a CCI ≥ 1. AR patients had a future risk of TDI, indicating a potentially linked disease pathophysiology. The association between AR and TDI is greater among general patients. Clinicians and caregivers should be aware of potential TDI co-morbidity in patients with AR.

Abstract
Sinus augmentation is a routine surgical procedure in dentistry. At present, various animal models are available for the research purpose on this topic. In particular, for the first time, we have performed a morphological study on sheep sinus, using cone beam computed tomography (CBCT), to precisely define the anatomy of the ovine sinus. Then, we compared the sheep and human sinus morphological parameters, in order to uniform the research approach to the sinus augmentation procedures and to standardize this experimental model. Six fresh heads of adult female sheep were studied with CBCT and histologic examination to determine the dimensions and the organization of the ovine maxillary sinus. The comparison of the dimensional values between man and sheep shows evident differences between the two species; CBCT offers detailed information for studying normal maxillary sinus. Human and sheep maxillary sinus show anatomical differences that must be taken into account in experimental procedures.

Abstract
PURPOSE The objective of this study was to assess the effects of concha bullosa variation on maxillary sinus volume and uncinate angle. METHOD The study group included 169 patients (338 sides) who underwent either surgical or medical treatment with the diagnosis of chronic rhinosinusitis. The paranasal sinus computed tomography of these patients was analyzed to measure maxillary sinus volume, uncinate angle and existence of concha bullosa. Subsequently, these variables were evaluated to find out possible relationship inbetween. RESULTS Mean maxillary sinus volume and uncinate angle at right and left sides were 15.21 ± 0.47 and 15.51 ± 0.48 mm(3), 30.57 ± 0.62° and 30.20 ± 0.68°, respectively. There was no difference between patients with or without concha bullosa in regard to maxillary sinus volume and uncinate angle at both sides. Maxillary sinus volume and degree of uncinate angle did not show any significant correlation at both sides; r = -0.124, p = 0.107 and r = -0.136, p = 0.078. CONCLUSION In conclusion, concha bullosa is a common anatomical variation at nasal cavity. The existence of concha bullosa does not have any association with the volume of maxillary sinus and angle of uncinate process.

Khajehahmadi S, Rahpeyma A, Hoseini Zarch SH. Association between the lateral wall thickness of the maxillary sinus and the dental status: cone beam computed tomography evaluation. IRANIAN JOURNAL OF RADIOLOGY 2014; 11:e6675. [PMID: 24693302 PMCID: PMC3955858 DOI: 10.5812/iranjradiol.6675] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/06/2012] [Revised: 04/28/2013] [Accepted: 07/17/2013] [Indexed: 11/16/2022]
Abstract
Background: Assessment of the lateral wall thickness of the maxillary sinus is very important in decision making for many surgical interventions. The association between the thickness of the lateral wall of the maxillary sinus and the dental status is not well identified. Objectives: To compare the thickness of the lateral wall of the maxillary sinus in individuals with and without teeth to determine if extraction of the teeth can lead to a significant reduction in the thickness of the maxillary sinus lateral wall or not. Patients and Methods: In a retrospective study on fifty patients with an edentulous space, the thickness of the lateral wall of the maxillary sinus,one centimeter above the sinus floor in the second premolar (P2), first molar (M1) and second molar (M2) areas was determined by cone beam computed tomography scans(CBCTs) and a digital ruler in Romexis F software (Planmeca Romexis 2.4.2.R) and it was compared with values measured in fifty dentated individuals. Three way analysis of variance was applied for comparison after confirmation of the normal distribution of data. Results: The mean of the wall thickness in each of these points was lower in patients with edentulous spaces; however it was not significant. There was no association between gender and the thickness of the lateral wall of the maxillary sinus, but location was associated with different thicknesses. Conclusions: The differences in the thickness based on the location and dental status necessitates assessment of the wall thickness of the maxillary sinus in addition to the current evaluation of bone thickness between the sinus floor and the edentulous crest before maxillary sinus surgery.

Three-dimensional volumetric computed tomographic scoring as an objective outcome measure for chronic rhinosinusitis: clinical correlations and comparison to Lund-Mackay scoring.

Abstract
BACKGROUND We aimed to test the hypothesis that three-dimensional (3D) volume-based scoring of computed tomography (CT) images of the paranasal sinuses was superior to Lund-Mackay CT scoring of disease severity in chronic rhinosinusitis (CRS). We determined correlation between changes in CT scores (using each scoring system) with changes in other measures of disease severity (symptoms, endoscopic scoring, and quality of life) in patients with CRS treated with triamcinolone. METHODS The study group comprised 48 adult subjects with CRS. Baseline symptoms and quality of life were assessed. Endoscopy and CT scans were performed. Patients received a single systemic dose of intramuscular triamcinolone and were reevaluated 1 month later. Strengths of the correlations between changes in CT scores and changes in CRS signs and symptoms and quality of life were determined. RESULTS We observed some variability in degree of improvement for the different symptom, endoscopic, and quality-of-life parameters after treatment. Improvement of parameters was significantly correlated with improvement in CT disease score using both CT scoring methods. However, volumetric CT scoring had greater correlation with these parameters than Lund-Mackay scoring. CONCLUSION Volumetric scoring exhibited higher degree of correlation than Lund-Mackay scoring when comparing improvement in CT score with improvement in score for symptoms, endoscopic exam, and quality of life in this group of patients who received beneficial medical treatment for CRS.

Abstract
Nasal obstruction most commonly occurs due to mucosal abnormalities and those in cartilage-bone structure such as nasal polyp, septum deviation, concha hypertrophy and chronic sinusitis in adults. Adenoid vegetation is the most prominent cause in childhood. In the present study, we aimed to investigate whether maxillary and palatal bone developments continue in patients with abnormalities causing nasal obstruction. As computerized tomography is the optimal imaging modality in nasal cavity abnormalities, CT scan findings of patients with Control nasal polyp, chronic sinusitis and septum deviation were retrospectively evaluated; and palatal curve changes were compared. In our study, it was found that maxillary bone curve was widened in adult patients with nasal polyp; this angle was further narrowed in those with chronic sinusitis; and maxillary bone curve narrowing and increase in the distance to palatal bone was smaller in patients with septum deviation than those in chronic sinusitis. In the light of these findings, we concluded that, in adults, maxillary and palatal bone developments continue in certain circumstances including nasal polyp, chronic sinusitis or septum deviation.

Abstract
AIMS Nose being the primary mode of air intake in humans can be obstructed in certain conditions and mouth takes over the process of breathing. As a result, there is a reduced or complete loss of function of nose, which shows underdevelopment or stunted growth (change in form). This can lead to impaired pneumatization that can result in dimensional changes in the sinus. OBJECTIVE To assess volume alterations in maxillary sinus as secondary and as compensatory mechanism to altered functional matrices by comparing overall maxillary sinus volume of mouth breathers with normal breathers in the age group 12-14 years and to evaluate effect of gender on maxillary sinus volume. MATERIAL AND METHOD Maxillary sinus volume calculated using manual segmentation method from CBCT scans of 25 normal breathers and 25 mouth breathers were compared. RESULTS Mean maxillary sinus volume of mouth breathers was significantly less than normal breathers (p < 0.05). CONCLUSION Mouth breathers showed lesser maxillary sinus volume but it is still uncertain whether the reduction in the volume of maxillary sinus is because the form of the maxillary sinus is affected due to improper functioning of nasal cavity or due to the underlying pathological condition resulting in poorly growing sinus.

Abstract
OBJECTIVE The aim of this study was to evaluate the developmental relationship between the volumes of paranasal sinuses and adenoid tissue by using a 3-dimensional (3D) reconstruction technique. STUDY DESIGN Cross-sectional study. SETTING Tertiary referral center. SUBJECTS AND METHODS Multislice computed tomography (MSCT) images were obtained using 3D reconstructions and a volume-rendering technique (VRT) in 69 boys and 35 girls aged 3 to 16 years, and bilateral maxillary, frontal, and sphenoid sinus volumes, as well as adenoid tissue volume marked in axial-coronal-sagittal planes, were calculated. The patients were grouped in 3 categories according to adenoid tissue volumes, and comparisons were made. RESULTS There was no significant difference between the right maxillary volume and left maxillary volume (P = .93). No significant difference was noted between the groups in terms of age and gender. There was no significant correlation between frontal, sphenoid, right and left maxillary, or total maxillary sinus volumes in all 3 groups of patients. CONCLUSION When classified according to adenoid tissue size, it was observed that increasing adenoid tissue volumes did not significantly affect the development of paranasal sinuses. Developmentally, there are no statistically significant correlations between the volumes of paranasal sinuses and adenoid tissues.
