An Enlarged Right Jugular Foramen

Jugular foramina are two openings in the base of the skull. Difference in diameter between two sides is noted, while right sided foramen is usually mentioned as the larger one. Rare cases have been reported with an enlarged jugular foramen. We report such a case with a right jugular foramen of a diameter 24mmX13mm. Microsurgery in the near future may exploid cases with greater openings. KEY WORDS: Base of the skull, Dry bone, Microsurgery.

A triple Cranial Vault lesion of Hyperostosis Frontalis Interna, Osteoma and Meningioma in a Cadaveric Skull

Cranial vault lesions are rare and may alter skull figure. Among them, osteomas are the most frequent entities found on burial remains. We present a skull (dry bone) which was unearth in the cemetery of Serres city in Northern Greece and was then donated to the Anatomy Department of the Democritus University of Thrace. The specimen presents a triple lesion and an odd figure, a reason which may explain why it was neglected for a long time period as an unwanted remain of a probably stigmatized person. Radiology (computed tomography) revealed a peculiar combination of a meningioma, an osteoma and a hyperostosis frontalis interna. KEY WORDS: Cranial Radiology, Meningioma en plaque, Hyperostosis.

Reproducibility and diagnostic value of a new wedge-guided bitewing image receptor-holding device

Objective To assess the reproducibility of a wedge-guided bitewing image receptor-holding device (IRHD-WG) compared to a commercially available bitewing image receptor-holding device (IRHD-XCP). Methods and materials Ten operators randomly acquired bitewing radiographs of four posterior regions (Premolar, Molar 1, Molar 2, Molar 3) distributed in two dry bone skulls and mandibles using 2 IRHDs (IRHD-WG and IRHD-XCP). The radiographs corresponding to the same region and IRHD but acquired by different operators were paired for reproducibility comparison. A total of 360 pairs of radiographs were randomized for analysis. Objective analysis consisted of extracting the pixel values from each radiograph and comparing the values between each pair by intraclass correlation coefficient. For subjective analysis, the IRHDs images were digitally removed. Five oral radiologists blinded for the study conditions classified the radiograph pairs according to their similarity and diagnostic value. The answers’ relative frequencies were compared by the chi-square test (α = 0.05). Results The IRHD-WG presented a higher reproducibility (Mean = 0.850; SD = 0.144) than the IRHD-XCP (Mean = 0.615; SD = 0.287) in the objective analysis. Radiographs acquired with the IRHD-WG were more similar than those acquired with the IRHD-XCP (p < 0.001). The diagnostic value of bitewing radiographs acquired with the IRHD-WG was considered superior to those acquired with the IRHD-XCP (p < 0.001). Conclusion For the objective and subjective analyses of reproducibility, the IRHD-WG performed better than the commercial IRHD-XCP.

Stature Estimation from Dry Bone and Radiographic Clavicular Measurements in A Thai Population

Stature is one of the main biological features which can be used to classify unidentified skeletal deceased. Also, precise population data is crucial for forensic anthropology frameworks. Nonetheless, the studies concerning this subject in Thailand are limited and regularly focus on long bones. This study attempts to establish stature estimation equations from clavicular dry bone and radiographic measurements. Both sides of the clavicular bones are separated from 25 female and 112 male deceased in an autopsy room situated in Bangkok, Thailand. Twelve variables of each side of the clavicle are measured. The study outcomes show that stature can be estimated by applying 3 variables in a stepwise regression analysis model in unidentified sex remains, with R2 = 0.49 and standard error of estimation (SEE) 5.238 cm. Moreover, the height of the sternal end of clavicle bones can be used to estimate stature in cases of fragmented clavicles recovered from crime scenes with R2 = 0.238 and SEE 6.353 cm. Maximum length shows the best correlation and model fit with stature (R = 0.562, R2 = 0.316 and SEE 6.020 cm) from radiographic measurements. Therefore, this study presents a complementary, beneficial method for forensic anthropologists to create biological profiles of unidentified skeletal remains in cases where the long bones are not obtainable. Moreover, stature estimation from radiographic measurements can be applied in cases of partial skeletonisation.
