Objectives: The aim of this study is to determine the incidence, location, and orientation of maxillary sinus septa in formalin embalmed cadavers. Materials and Methods: The study was conducted on 210 cadaveric heads available in our department. After taking the mid-sagittal section the specimens were opened from the medial aspect and the sinus cavity was explored for the presence of maxillary sinus septa, their anatomical plane, location and dimensions. Results: The mean linear distance between maxillary sinus floor and its anatomical ostium was 26.76±5.21 mm and 26.91±4.96 mm on right and left side, respectively. A total of 59 maxillary sinus septa (28.1%) were observed in 210 maxillary specimens. Septae were most common, 33 septa (55.9%), in the middle region (between first and second molar tooth) of the sinus cavity. The maxillary sinus membrane (Schneiderian membrane) adhered tightly to the maxillary sinus and over the septae. Significantly more maxillary sinus septa were observed in edentulous maxillae in comparison to the dentate upper jaw. Conclusion: Knowledge of location of maxillary sinus ostium is mandatory for the rhinologist for drainage of secretions in maxillary sinusitis. The morphological details of maxillary sinus septa, particularly their location and anatomical planes, will guide dentists in performance of safe implant surgeries. The maxillary antrum septa of category I and II may complicate the procedure of inversion of bone plate and elevation of sinus membrane during maxillary augmentation surgeries. The category III septa observed in the sagittal plane were embedded by one of the branches of the infraorbital nerve in it, and if accidentally cut will lead to infraorbital nerve palsy in maxillary sinus surgeries.

Plate fixation has become the preferred approach for treating displaced midshaft clavicle fractures. However,plate fixation of the clavicle presents several unique challenges, including its complex bony architecture and its immediatesubcutaneous location. In many cases, we have observed that precontoured implants do not conform to the clavicularanatomy, and many patients complain of postoperative implant-related discomfort. A total of 111 clavicles, both left andright sides, were examined to match two commonly used designs of anatomical pre-contoured superior anterior clavicleplates, with and without lateral extension. The anteroposterior (AP) plane congruence of the plate to the underlying bone, thevertical gap between the bone and plate, and the length of the plate that was off the bone either anteriorly and/or posteriorlyat both ends of the clavicle were measured. The scoring system was used to determine the fit of the implant on the clavicle asanatomic, good, or poor. We found that the maximum superior bow of the clavicle was lateral to the midline by 30.75 mmand 30.5 mm on the right and left sides, respectively. The magnitude of the bow was 4.28 mm and 4.46 mm on the right andleft sides, respectively. We also found that the plate was a poor fit in 75.86% of cases on the left side and 73.5% of cases on theright side. Manipulating the plates during surgery was very difficult in the AP plane.
