Abstract
This study analyzed the presence of antral septa in the maxillary sinus. A septum is a barrier of cortical bone and may split the sinus into two or even more than two cavities. Between 13% and 35% of the sinuses have these septa. Different methods to detect the presence of maxillary septum before dental surgery can be used. To know the prevalence of a septum before an external sinus floor elevation could be necessary to avoid surgical complications. CT-scan images collected from 120 maxillary sinuses of 60 patients from two dental clinics, which were processed by Fan beam CT scan, GEMS ZeusRP/ Simplant and GE/Dental Scan by Radiology department of Cathay General Hospital were included in this study. The locations and distribution of spikes and septum’s were identified from the images and recorded. According to the most frequent areas, 3 categories were classified: Second premolar (P2), first molar (M1) and second molar (M2) according to the related tooth position. The difference between sides, sites and incidence were compared. Out of 60 patients, 17 showed no septum identified in both sinuses and 8 showed on one sinus. The rest can be detected on both sides. The incidence of a spike in the maxillary sinus in patients is 43/60. From 120 sinuses, 68 sinuses with 85 spikes or septum’s were identified. The incidence of a spike in the maxillary sinus on sinus is 85/120. Three areas were categorized as second premolar (P2), first molar (M1) and second molar (M2) according to the correlated tooth position. Spikes were 33 in second premolar (P2) position, 22 in first molar (M1) and 30 in second molar (M2) position; 48 on the right side and 37 on the left. The incidence of a spike in the maxillary sinus in patients is high (71.67%) and on sinus (70.83%). The incidence of sinus with spike is higher on right (39 vs. 29). The incidence of spikes detected slightly higher on right sinuses (48 vs. 37). Spikes were detected higher in second premolar (P2) and second molar (M2) than first molar (M1).
