Evaluation of Maxillary Sinus Volume in Cleft Alveolus Patients Using 3-Dimensional Computed Tomography

Abstract Background The maxillary sinus has been considered as an important factor that affects the development of craniomaxillofacial bone. However, the correlation between the maxillary sinus and skeletal malocclusion is controversial. This study aimed to compare the dimensions of the maxillary sinus in patients with different vertical growth patterns and investigated the correlation between the maxillary sinus and craniofacial parameters.Methods This descriptive study included 90 patients from age 15 to 20 years old. According to the vertical growth patterns that were classified by MP-FH (angle between the mandibular plane and Frankfort horizontal plane), they were equally divided into three groups: high-, low- and normal-angle, and the gender ratio was 1:1. Cephalometric tracings were conducted from CBCT images, which were also used to measure the dimensions and volume of the maxillary sinus. Data were analyzed with one-way ANOVA, Pearson’s correlation coefficient, and multiple comparison LSD.Results The variables of the maxillary sinus, including the volume, length, and width, among different groups, were significant(p<0.05). The variables of mandibular body length were significantly correlated with the volume of the maxillary sinus (p<0.01), and the coefficient was 0.425.Conclusions The maxillary sinus volume, length, and width were larger in low-angle patients. The mandibular body length had a significantly positive correlation with the maxillary sinus volume.

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.

OBJECTIVE: To evaluate change of the maxillary sinus volume according to patient age and gender by using a 3-dimensional (3-D) reconstruction of computed tomography images. STUDY DESIGN AND SETTING: One hundred seventy-three people (totaling 238 maxillary sinuses) who had undergone paranasal sinus CT scan between December 2000 and November 2003 and had no evidence of inflammation or hypoplasia in the CT finding and had no specific history of paranasal sinus surgery or maxillofacial trauma were retrospectively analyzed. The 3-D reconstruction images were obtained by using a surface-rendering technique (Vworks; CybeMed, Seoul, Korea) on a personal computer. The mean volume of maxillary sinus was evaluated according to patient chronologic age and gender. The ratio of the maximum horizontal and half-horizontal extension for the estimation of the morphological change of maxillary sinus and the degree of descent of the sinus below the nasal floor were evaluated in the 3-D image. RESULTS: The development of the maxillary sinus continued until the 3rd decade in males and until the 2nd decade in females. The mean maxillary sinus volume in early adults was 24,043 mm 3 (males) and 15,859.5 mm 3 (females). There was a significance difference in the sinus volume ( P < 0.05) according to gender, and there was a significant difference in the maxillary sinus volume according to age before it reached maximum. After its maximum growth period, however, there was no significant difference in the volume change of maxillary sinus and the descent below the nasal floor between two adjacent groups. CONCLUSIONS: The growth of the maxillary sinus continues until the 3rd decade in males and the 2nd decade in females. Therefore, a maxillary sinus operation affecting the bony structures before these ages might affect the development of the sinus and needs to be performed carefully
