Prevalence and morphological variations of maxillary sinus septa in different age groups: a CBCT analysis

Abstract

Prevalence and morphological variations of maxillary sinus septa in different age groups: a CBCT analysis BACKGROUND: There are limited data from Saudi Arabia on the prevalence and characteristics of maxillary sinus septa. OBJECTIVE: Determine the prevalence and morphological characteristics of septa in the maxillary sinus and their relationship to gender and age using cone beam computed tomography (CBCT). DESIGN: Cross-sectional SETTING: CBCT images acquired from the maxillofacial radiology department in a dental school. PATIENT AND METHODS: CBCT scans of 1010 maxillary sinuses from 505 patients were analyzed to determine the prevalence, location, type, and orientation of maxillary sinus septa. Descriptive statistics, chisquare tests and t tests were used to analyze the data. MAIN OUTCOME MEASURES: The prevalence, location, type, and orientation of maxillary sinus septa. SAMPLE SIZE: 1010 sinuses from 505 patients. RESULT: Approximately 46% of the studied patients had maxillary septa, which were present in 370 (37%) sinuses. About 64% of the septa were present on the right side and 85.7% of all septa were mediolaterally oriented. The mean height of the septa was 6.06 mm (0.84) in the right sinuses and 5.70 mm (0.93) in the left sinuses. Multiple septa were found in 101 patients (20%). Among males, 58.5% had septa compared to 34% of females (P<.001.) A significant positive association was found between age and the presence and number of septa, P<.001. CONCLUSIONS: Maxillary sinus septa were highly prevalent with various heights and directions among the studied sample. Careful assessment of different anatomic variation must be conducted prior to any maxillary sinus augmentation, particularly in older patients. LIMITATIONS: Cross-sectional evaluation of CBCT images from one dental school patient population; thus, the findings cannot be generalized to other populations. CONFLICT OF INTEREST: None.

Maxillary Sinus Septa: Prevalence and Association With Gender and Location in the Maxilla Among Adults in Sana'a City, Yemen

“…The result of the current study showed no association between septal incidence and sex as septal prevalence was almost equal in both sexes (males=52.96% vs females=54.2%, with OR=0.95, 95% CI=0.69-1.3, p=0.75) (Table 3). These results were different from the observations reported by Shen et al, 9 Al-Zahrani et al, 36 Orhan et al, 37 ; the male septal rate was higher than that of female patients. Obtained results also differ from those reported by Park et al, 1 and Malik et al, 38 where the septum rate is higher in females than in males 1, 38 .…”

Analysis of the Prevalence, Location, and Morphology of Maxillary Sinus Septa in a Northern Chinese Population by Cone Beam Computed Tomography

“…Incidence Rate. Previous studies indicated that the incidence of maxillary sinus septa is various and the range of prevalence is from 26.5% to 69% [8,9,14,[17][18][19][20][21][22][25][26][27].…”

“…In addition, this study found that there was no significant difference in the incidence rates among different age groups. Most studies obtained the same conclusion while few others did not, and this might be the result of the difference of age categories [22]. 4.5.…”

“…The height of maxillary sinus septum also varied with the positions, sides, and population. The mean height was in a range between 1.63 ± 2.44 mm and 13.11 ± 3.82 mm [14,18,[20][21][22]. More attention should be paid to the anatomy variation of maxillary sinus septa before maxillary sinus floor elevation.…”

Anatomical Changes in a Case with Asymmetrical Bilateral Maxillary Sinus Hypoplasia

“…We evaluated the MSH in all three anatomical planes, as well as on three-dimensional renderings. Other CBCT studies of the maxillary sinus either only listed the MSH among other anatomic variations of the sinus [ 28 ] or did not mention MSH [ 29 ].…”
