Abstract
OBJECTIVE The aim of this study is to evaluate the maxillary sinus (MS) volume and pathologies, nasal septum (NS) deviation, and MS septa formation in children with and without cleft lip and palate (CLP); also to investigate the possible causes of MS pathologies. MATERIALS AND METHODS Cone Beam Computed Tomography (CBCT) images of 200 (100 CLP, 100 control) children (5-18 years old) were evaluated from the computer database of Marmara University Faculty of Dentistry. Children with a history of maxillofacial trauma, diseases that affect bone metabolism, orthognathic surgery, extrinsic pathologies of the MS, and accompanying syndromes were excluded. NS deviation, MS septa formation, volume, and pathologies evaluated using Mimics® software. In statistical evaluations; Student t test, paired sample t test, Chi-Square test, Fisher's Exact Chi-Square test, Continuity Correction, Chi-square analysis in one-eyed layout, McNemar test, and logistic regression analysis were used. RESULTS Total MS volume was smaller in the CLP group (21 232 mm3) than in control children (23 763 mm3) (P:0.026). NS deviation and MS pathology were more frequent in the CLP. In logistic regression analysis, there was no significant relation between the presence of NS deviation and pathology in MS. The presence of CLP increased the risk of MS pathology by 2.6 times. CONCLUSION We found that children with CLP have less MS volume and an increased rate of NS deviation and MS pathology compared to the control group. Further radiological and clinical studies are needed to explain the predisposing factors of MS pathology in children with CLP.

Abstract
OBJECTIVES This study is performed to compare the paranasal sinus volumes in paediatric unilateral cleft palate (UCP) and healthy patients. METHODS Cone-beam computed tomography (CBCT) images of 80 patients (40 boys, 40 girls) with UCP and 80 healthy individuals (40 boys, 40 girls) were evaluated. Paranasal sinus volumes were segmented and measured using ITK-SNAP software. Descriptive statistics, Kolmogorov-Smirnov, paired sample t-test and student t-test were performed for statistical analysis. RESULTS The volumes of ethmoid, frontal and sphenoid sinus on the cleft side were not significantly different than the non-cleft side (p>0.05) in UCP patients. Maxillary sinus volume of the cleft side in UCP patients was significantly lower than the non-cleft side (p<0.05). Mean maxillary sinus volume in UCP patients was 11825.23±509.95 mm3 at the cleft side and 13497.85±358.07 mm3 at the non-cleft side. While the mean volumes of ethmoid and sphenoid sinuses of patients with UCP were not significantly different from healthy individuals (p>0.05), the mean volumes of maxillary and frontal sinuses were significantly lower than healthy individuals (p<0.05). The mean maxillary sinus volume in UCP patients was 25323±597.8 mm3 and 26666±874.3 mm3 in the control group. The mean frontal sinus volume in UCP patients was 5633±323.1 mm3 and 5735±315.2 mm3 in the control group. CONCLUSIONS UCP caused a significant reduction in maxillary and frontal sinus volumes. The results of the current study show that paranasal sinus volumes in patients with UCP should be examined in more detail to make more risk-free and effective treatment plans.

Abstract
OBJECTIVES To determine pre-operative cleft volume and evaluate cleft´s impact on surrounding anatomical structures in children and adolescents with orofacial clefts using cone bean computed tomography (CBCT) imaging. METHODS The present retrospective study retrieved CBCT examinations of 68 patients from a previous study. The examinations had been exposed either before (n = 53) or after (n = 15) alveolar bone grafting. Pre-operative volume of cleft was determined, and type and location were evaluated. Morphological changes on the adjacent anatomical structures, including the incisive foramen, the nasal septum and floor, and the inferior turbinate, were assessed. RESULTS Mean bilateral cleft volume was 0.76 cm3, while mean unilateral cleft volume was 1.08 cm3; the difference was significant (p < 0.001). Variation in cleft volume, however, was large. The incisive foramen was not visible in the majority of cases with bilateral clefts (71%); the difference was significant (p = 0.001). In cases with unilateral clefts, the nasal septum in 87% was curved towards the cleft or graft side. Also, the mean size of the widest part of the inferior turbinate was 8.8 mm on the cleft or graft side and 10.4 mm on the non-cleft side. The difference was significant (p < 0.001). CONCLUSIONS When required, CBCT is a feasible method for quantitatively illustrating alveolar clefts and their impact on the morphological development of surrounding structures. Variation in cleft volume was large.

Abstract
OBJECTIVE The development of the maxillary sinus is different in patients with cleft lip and palate (CLP) compared to non-CLP individuals. To investigate the prevalence and features of maxillary sinus septa (MSS) in patients with CLP in comparison with the non-CLP population. DESIGN Retrospective study. INTERVENTION Cone beam computed tomography (CBCT) evaluation. SETTING CLP center in Shiraz faculty of dentistry, Iran. PATIENTS A total 306 sinuses (88 cleft and 218 noncleft) on 153 images (CLP group: n = 66; control group: n = 87) were examined to determine the prevalence of septa and characterize them. MAIN OUTCOME MEASURES Sinus septa were characterized according to height, orientation, angle, origin, and location. The chi-square test, Mann-Whitney U test, and Fisher's exact test were used for statistical analysis. RESULTS The prevalence of septa was 28.9% and 32.1% in the CLP and control groups, respectively. No significant difference was found between the study groups in terms of prevalence, location, and orientation of MSS. The average height and angle of septa were significantly higher in the control group compared to the CLP group. Inferior origin was significantly more prevalent in the control group than in the CLP group (P = .004). CONCLUSION There was no difference in the prevalence of MSS between patients with CLP and non-CLP individuals. However, certain features of the septa were different in patients with CLP.

Abstract
Cleft lip and palate (CLP) is one of the most common congenital craniofacial anomalies, which can change the morphology of the skull, face, and maxillary sinus due to the disruption in the fusion of palatal shelves. This study aimed to investigate the volume and dimensions of the maxillary sinus in unilateral CLP patients along with comparing the healthy and affected sides. This cross-sectional study was conducted on 27 cone-beam computed tomography stereotypes (14 male and 13 female) of patients with unilateral CLP. Maxillary sinuses were traced separately on each side and analyzed by OnDemand3D software in a separate room with low light. The height and base area of the maxillary sinuses were measured on each side. After dividing each sinus into smaller pyramids, the volume of the sinus was obtained using the partial frustum model method and analyzed by paired t test. There was no significant difference between cleft and noncleft sides in terms of mean volume and height of the sinus ( P > 0.05). The average area of the sinus base on the cleft side was 32.77 mm 2 more than the noncleft side, and this difference was statistically significant ( P = 0.027). The mean upper maxillary sinus volume on the cleft side was 541.62 mm 3 larger than the noncleft side, but this difference was not statistically significant ( P = 0.075). Considering the age groups, the average upper sinus volume on the cleft side in patients under 20 years old was 4.66 mm 3 less than the noncleft side. In the age group of more than 20 years, the average volume of the upper sinus on the cleft side was 978.66 mm 3 more than the noncleft side. The mean volume of the lower sinus on the cleft side was 505.92 mm 3 lower than the noncleft side, and this difference was statistically significant ( P = 0.010). The average area of the sinus base of the cleft side was significantly higher than the noncleft side. Also, the lower sinus volume of the cleft side was significantly lower than the noncleft side. However, no significant difference was observed in upper sinus volume between the cleft and noncleft sides.

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.

Abstract
OBJECTIVES To compare the maxillary sinus volume between both sides in adult patients with upper occlusal canting (>2 mm cant) and a control group (≤2 mm cant) using cone-beam computed tomography scans. MATERIALS AND METHODS This retrospective study included a total of 84 scans (42 scans per group) according to predetermined selection criteria. OnDemand 3-D™ software was used for volumetric and linear measurements of the maxillary sinus. Maxillary occlusal canting was determined at the level of the maxillary first molars. It was defined as the vertical difference between right and left sides relative to the Frankfort horizontal plane. Non-parametric tests were applied. RESULTS The median difference in the maxillary sinus volume between the sides was statistically significant between the control and cant groups (P < 0.001). Also, the median difference in the maxillary sinus craniocaudal height and apex sinus distance between the sides was statistically significant between the control and cant groups (P < 0.05 and P < 0.001, respectively). CONCLUSION In adult patients, maxillary occlusal canting of more than 2 mm was associated with asymmetric maxillary sinus volumes. In the cant group, maxillary first molars on the canted-down side were in close proximity to the sinus floor, which suggests a limited leeway for molar intrusion.

Abstract
The paranasal sinuses (maxillary, frontal, ethmoid, and sphenoid sinuses) are complex anatomical structures. The development and growth of these have been investigated utilizing a number of different methods ranging from cadaveric analysis to modern cross sectional imaging with 3D modeling. An understanding of normal pediatric paranasal sinus embryology and development enables us to better determine when pathology may be affecting the normal developmental process. Cystic fibrosis, chronic sinusitis, deviated nasal septum and cleft lip and palate are some of the conditions which have been shown to effect paranasal sinus development to varying degrees. Functional endoscopic sinus surgery (FESS) is becoming increasingly common and an understanding of sinus anatomy together with when periods of rapid growth occur during childhood is important clinically. Although concerns have been raised regarding the impact of FESS on facial growth, there is limited evidence of this in regards to either changes in anthropomorphic measurements or clinical assessments of symmetry post operatively.

Abstract
The aim of this systematic review and meta-analysis was to evaluate the maxillary sinus characteristics of patients with cleft lip and palate (CLP). The study included manuscripts which met the following criteria: (1) study of individuals with CLP in any age group or gender and (2) study of individuals in whom assessment of maxillary sinus characteristics had been done by cone-beam computed tomography. Studies with (1) individuals having special health-care needs and (2) individuals with any syndrome affecting the development of the head and neck were excluded. In total, 11 articles were included in the review, based on the inclusion and exclusion criteria. Pooled maxillary sinus volume (MSV) on the cleft sides of patients with unilateral cleft lip and palate (UCLP) was found to be 9433.14 mm3 (95% CI, 7453.99-11 412.30), which was significantly smaller than that of controls. The meta-analyses also revealed significantly reduced MSV on the cleft sides of patients with UCLP. The differences between cleft and noncleft sides of the patients with UCLP were not found to be statistically significant. Strength-of-evidence was found to be moderate in 4 characteristics, along with 10 out of 11 articles showing low risk-of-bias. It was concluded that MSV was reduced and mucosal thickening was increased/present in patients with CLP as compared with controls. The differences between MSV of cleft and noncleft sides of the patients with UCLP could not be established. However, heterogeneity was found in terms of sample size, stratification of samples by age, and evaluation of some confounding factors.

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
OBJECTIVES The detection of anatomical variation impairments in patients with cleft lip and palate (CLP) is crucial in combined orthodontic and maxillofacial surgical treatments. Therefore, this study aimed at evaluating the anatomical maxillary sinus characteristics, nasal septum deviation (NSD), and mucosal thickening of the maxillary sinus in patients with CLP using cone beam computed tomography (CBCT). DESIGN The CBCT images were classified into 3 groups of unilateral cleft lip and palate (UCLP; n = 40), bilateral cleft lip and palate (BCLP; n=14), and noncleft (control; n = 54). Subsequently, the maxillary sinus linear dimensions were assessed. Height, width, depth, infundibulum height, and ostium width were assessed as quantitative measures, whereas nasal septum deviation and mucosal thickening were assessed as qualitative measures. One-way analysis of variance and χ2 tests were utilized to identify any significant differences among the groups regarding the aforementioned variables. RESULTS Significant differences were observed among the groups regarding maxillary sinus height and depth, NSD, and mucosal thickening. Moreover, UCLP and BCLP groups showed higher incidence of NSD and mucosal thickening. However, the size of maxillary sinus height and depth was lower in the UCLP and BCLP groups. CONCLUSION The results showed that BCLP and UCLP groups obtained lower maxillary sinus height and depth compared to the control group. On the other hand, incidence of the NSD and mucosal thickening was significantly higher in UCLP and BCLP groups than those in the control group.

OBJECTIVE The aim of this study was to evaluate the posterior superior alveolar canal (PSAC) in patients with cleft lip and palate (CLP) as compared to patients with no cleft lip and palate (NC) using cone-beam computed tomography (CBCT). MATERIALS AND METHODS This was a retrospective multicenter study based on two steps: (1) evaluating intra- and inter-calibration and (2) detecting the presence or absence of PSAC and its location, diameter, and anastomosis with anterior superior alveolar canal. RESULTS A total of 300 patients were selected for the study, out of which 150 were categorized as CLP (75 men, 75 women; mean age: 29.8 years) and 150 were categorized as NC (75 men, 75 women; mean age: 40.3 years). PSAC in patients with CLP and NC was visible in 100% of the cases, in men and women, bilaterally. PSAC location in CLP was middle and upper third of the maxillary sinus as compared to NC (lower third) (chi-squared < 0.001). PSAC mean diameter in CLP was 1.12 mm. It was larger compared to 0.6 mm in NC (t-test < 0.0001). CONCLUSION PSAC location in patients with CLP was predominantly in the middle and upper third of the maxillary sinus, compared with NC. PSAC mean diameter in CLP was 1.12 mm. It was larger compared to that of 0.6 mm in NC. CLINICAL RELEVANCE These anatomical variations in CLP are important and should be acknowledged by surgeons for the following reasons: (1) to perform pre-surgical planning, (2) to avoid bleeding, and (3) to avoid neurosensory alterations.

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 AND OBJECTIVE Maxillary sinus disease is frequently observed in patients with unilateral cleft lip and palate (UCLP). The anatomical variations of maxillary sinus and maxilla may play a role in the high incidence of sinusitis. The aims of this study were to evaluate and compare the three-dimensional (3D) structural features of maxillary sinus and maxilla in UCLP adolescent patients between the defect and non-defect sides, and investigate the morphological relationship between the maxillary sinus and maxilla on the defect side by using cone-beam computed tomography (CBCT). METHODS CBCT images were acquired from 42 UCLP adolescent patients. Maxillary sinus and maxilla on the defect and non-defect sides were segmented respectively and assessed three dimensionally, and the comparison was performed by paired t-test. A multiple linear regression was conducted to investigate the morphological relationship between the maxillary sinus and maxilla on the defect side. RESULTS No statistically significant difference was observed in any parameter of the maxillary sinus between the defect and non-defect sides (P > 0.05). Significant differences were observed in the length, anterior width, anterior height, and volume of the maxilla between the defect side and non-defect sides (P < 0.05). The parameters of maxillary sinus were significant related to the posterior width and height of maxilla on the defect side. CONCLUSION Adolescent patients with UCLP present similar 3D structural features of the maxillary sinus on both sides. Significant differences of the maxilla between the defect and non-defect sides were displayed in the area adjacent to the defect but not showed in the posterior portion of maxilla. Certain structures of the posterior portion of maxilla contribute to the variability of maxillary sinus.

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
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
PURPOSE The aim of this study was to measure the cortical bone thickness of the infrazygomatic crest area in individuals with unilateral cleft lip and palate using cone beam computed tomography for placement of miniplates used for bone anchored maxillary protraction. MATERIALS AND METHODS CBCT scans were obtained from 31 non-syndromic UCLP children diagnosed with maxillary hypoplasia (17 males, 14 females, mean age: 11.9 years). 5 horizontal and 5 vertical reference planes were drawn at the infrazygomatic crest area. The cortical bone thickness at 25 intersection points on the cleft side and the non-cleft side was measured. RESULTS The mean cortical bone thickness of the 25 measured points was 1.19 mm on the cleft side and 1.17 mm on the non-cleft side with no significant difference. The greatest cortical bone thickness was found to be at the most superior, posterior point (H+6, V+0), which was 1.49 mm on the cleft side and 1.47 mm on the non-cleft side. The thinnest mean cortical bone thickness was measured at the most inferior, anterior point (H-2, V-8), which was 0.94 mm on the cleft side and 0.95 mm on the non-cleft side. There was no significant difference between males and females.

Abstract
OBJECTIVES/HYPOTHESIS Individuals with orofacial clefts often experience respiratory problems because of nasopharyngeal abnormalities. Pharyngeal airway morphology is thought to differ among the various cleft types. We measured three-dimensional (3D) airway volume using cone-beam computed tomography (CBCT) analysis to evaluate and compare pharyngeal airways in Japanese preschoolers with and without orofacial clefts. STUDY DESIGN Retrospective case-control study. METHODS We enrolled 83 subjects (37 boys, 46 girls; mean age = 4.66 ± 0.56 years) with nonsyndromic orofacial clefts and 16 noncleft healthy subjects (seven boys, nine girls; mean age = 5.30 ± 0.52 years) as controls. The subjects were divided into five groups. Four groups were based on the cleft type: isolated cleft palate, unilateral cleft lip and alveolus), unilateral cleft lip and palate, and bilateral cleft lip and palate. The fifth group included the noncleft controls. All subjects were examined with CBCT, and the 3D airway volume was measured. We analyzed group differences statistically using analysis of covariance with the Bonferroni post hoc pairwise comparison tests for the corrected means. RESULTS Compared with the noncleft group, each cleft group exhibited significantly decreased total and nasal airway volumes and increased superior and inferior pharyngeal airway volumes. The differences were all statistically significant. CONCLUSIONS Our findings suggest that anatomical differences exist in pharyngeal airway volumes among various cleft groups and in those without a cleft.

Abstract
Trans-sutural distraction osteogenesis (TSDO) promotes midface growth in growing cleft lip and palate (CLP) patients with midfacial hypoplasia. The superficial skeletal changes after therapy revealed rotation advancement of the midfacial skeleton associated with differential displacement in each segment, but reports rarely focus on the changes of internal structures, including circummaxillary sutures, the maxillary tuberosity and the maxillary sinus, which may play a crucial role during this process. This study evaluated the computed tomographic (CT) images of 26 growing CLP patients who received bone-borne TSDO therapy. The results revealed that the most prominent new bone formation occurred in the pterygomaxillary suture and pushed the P-point forward. The maxillary first molar exhibited significantly greater advancement compared with the P-point due to the growth of the maxillary tuberosity. The contribution ratio values of the advancement of the maxillary tuberosity and P-point to the maxillary first molar were 26% and 74%, respectively, in UCLP and 25% and 75%, respectively, in BCLP. Furthermore, the maxillary sinus volume was also significantly increased. In conclusion, midface growth with bone-borne TSDO therapy depends on both secondary displacement promoted by sutural bone formation mainly in the pterygomaxillary suture and primary displacement by growth of the maxillary tuberosity and maxillary sinus volume.

Abstract
PURPOSE Ectodermal dysplasia (ED) is a congenital syndrome characterized by abnormal development of ectodermal structures, such as skin, hair, nails, teeth, or salivary glands. Patients with ED demonstrate craniofacial dysmorphology, midfacial hypoplasia and hypodontia. The aim of this study is to evaluate volume and surface area of maxillary sinus and craniofacial structures in patients with ectodermal dysplasia (ED) using cone-beam computed tomography (CBCT) images. METHODS The CBCT images of 20 patients with ED (study group) and 20 healthy individuals (control) which are equal in terms of age and gender were evaluated. After a three-dimensional analysis and segmentation of each maxillary sinus, the volume and surface area were calculated. Craniofacial dimensions were measured on the sagittal planes of the CBCT images. The results of the ED and control groups were statistically compared. RESULTS The right and left sinus volumes and surface areas were significantly lower in the ED group than in the control group (p < 0.05) while the SNA was significantly higher (p < 0.05). ANB and SN-GoMe were also lower in patients with ED than in controls (p < 0.05). The difference in SNB values between the two groups was not significant (p > 0.05). CONCLUSIONS The volumes and surface areas of both maxillary sinuses were found to be smaller in patients with ED compared to healthy individuals. Class III malocclusion with maxillary retrusion is a characteristic craniofacial feature of these patients.

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
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).

Abstract
OBJECTIVE This study aimed to compare sinus volume and dimensions in patients with high-, low-, and normal-angle vertical growth patterns using cone-beam computed tomography (CBCT). MATERIALS AND METHODS According to skeletal vertical face growth patterns, 60 adults (31 female, 29 male, average age: 29.90 ± 10.91 years) were divided into three groups equally: high-angle, low-angle, and normal-angle groups. Cephalometric tracings were obtained from CBCT images and SN-GoGn (angle between Sella-Nasion line and Gonion-Gnathion line) cephalometric angular measurements used for the classification of skeletal vertical pattern evaluations. Morphological and dimensional changes in the maxillary sinuses were evaluated on CBCT images. Data were analyzed using the one-way ANOVA, Kruskall-Wallis, and Mann-Whitney U statistical tests. RESULTS There were no statistically significant differences among the groups in terms of age (p > .05). The low-angle vertical growth pattern group showed significantly better results than the high-angle group in the right maxillary sinus length parameter (p < .05). CONCLUSION According to the results, the high-angle subjects showed statistically lower values in terms of maxillary sinus length and width than the low-angle subjects. There were no effects of vertical face development on right and left maxillary sinus volumes. The results of this study may be useful in maxillary sinus evaluation when planning for orthognathic surgery and orthodontic mini screw application in various vertical face patterns.
