“…Numerous skeletal differences are observed amongst ethnic groups, particularly between Asian and other ethnic groups, as reported by Algahefi et al The anteroposterior dimension of the skull in Caucasian subjects is larger than that in Chinese subjects. Except for the anterior sinus index and Sg-N-G angle, which were significantly larger in Chinese patients, the S-N and S-G dimensions and SN G-M angle were statistically significant in Caucasians compared with Chinese patients [15].…”

Background This study aimed to compare the maxillary sinus dimensions and surface area in accordance with skeletal malocclusion, gender and ethnicity factors in a sample of Chinese and Yemeni patients. Methods This cross-sectional study analysed 180 maxillary sinuses using 180 lateral cephalometric radiographs. The patients were subdivided into two ethnic groups: Chinese and Yemeni. Each ethnic group comprised 90 patients, and men and women were divided equally. Each ethnic group was classified into three skeletal classes using ANB and Wits appraisal (skeletal Classes I, II and III). Pearson’s correlation coefficient was also used to assess the relationship between maxillary sinus dimensions and cephalometric parameters. Results Men had larger maxillary sinuses than women; skeletal Class II had a higher length and surface area increase than other skeletal classes, although skeletal Classes I and II were almost equal in height. Except for the maxillary sinus length, none of these findings were statistically significant. The maxillary sinuses in Chinese are larger than those in Yemenis (P = 0.000). These variables were positively correlated with SNA, SNB and Co–A. The maxillary sinus length and Co–Gn were positively correlated. The NA–APO and NA–FH angles were also correlated with the maxillary sinus surface area. However, the gonial and GoGn–Sn angles negatively affected the maxillary sinus dimension and surface area. Conclusions Men had larger maxillary sinuses than women in both ethnic groups, and Chinese individuals had larger maxillary sinuses than Yemenis. Skeletal Class II malocclusion of both ethnicities had larger maxillary sinus dimensions. Furthermore, the maxillary sinus dimensions correlated with cephalometric parameters.

“…Various factors, such as race and malocclusion, could affect the size of the maxillary sinuses [14][15][16][17]. According to Shrestha, in skeletal Class II malocclusion, the maxillary sinus is greater than that in skeletal Class III [16].…”

“…They were conducted in six nations, with India having the highest number (n = 3) 23,24,35 . The rest of the studies were carried out in Iran [ 13 ], Nepal [ 35 ], Yemen [ 26 ], China [ 26 ], and Turkey [ 36 ]. There was a total of 1101 participants, who were examined with cephalometric X-rays and had different skeletal malocclusions.…”

“…The effect of the frontal air sinuses’ formation on the development of various skeletal malocclusions has been studied [ 13 , [23] , [24] , [25] ], but the results have been controversial. Some studies report a relationship with class III skeletal malocclusion [ 13 , [23] , [24] , [25] , [26] ], and other studies report a relationship with class II skeletal malocclusion [ [27] , [28] , [29] ]. Other studies have linked the frontal sinus with the vertical growth pattern [ [30] , [31] , [32] ].…”

The present study explored the association between the craniofacial sagittal skeletal patterns and frontal sinus dimensions in Germans. This cross-sectional study included orthodontic patients with age ranging from 11 to 18 (80 males, 82 females). Lateral cephalograms were used in the cephalometric and frontal sinus analysis. Cephalometric analysis was performed to measure SNA, SNB and ANB angles. Frontal sinus measurements were performed to obtain the frontal sinus height, antero-posterior dimension and frontal sinus lateral projection area. The frontal sinus dimensions were compared between genders with Mann Withney test. Kruskal Wallis and Dunn's post-hoc tests were used to compare the mean differences between the skeletal malocclusions. Spearman’s correlation test and linear regression model were also performed. Statistical significance was set at 5%. Regarding skeletal malocclusion, 71 patients presented class I, 81 class II and 10 class III skeletal malocclusion. The frontal sinus height (p=0.009), frontal sinus antero-posterior dimension (p=0.001) and frontal sinus lateral projection area (p=0.007) were bigger in males than in females. The frontal sinus antero-posterior dimension was significantly greater in the class III when compared to the class I (p=0.010) and class II (p=0.027). Frontal sinus lateral projection area was also bigger in class III than class I (p=0.039). In the linear regression model a significant association was observed between frontal sinus lateral projection area and class III (skeletal class I as a reference). In conclusion, our result suggests that the frontal sinus lateral projection area might present morphometric differences in German teenagers with skeletal class III malocclusion.
