    Absence of Frontal Sinus in Turkish Individuals
    (Yonsei University College of Medicine, 2003) Aydinlioǧlu, A.; Kavakli, A.; Erdem, S.
    The frontal sinus has been used for personal identification since the early part of the 20th century as a result of its tremendous interindividual variation. The frontal sinus is present in approximately 90% of adults. However, some populations have a higher proportion of people without a frontal sinus. This study investigated the frequency of the absence of frontal sinuses in Turkish individuals. The present study was performed retrospectively on the CT scans of the paranasal sinuses in the axial and coronal planes from a series of 1200 cases. A bilateral absence and a unilateral absence of sinuses were found in 3.8% and 4.8% of cases, respectively. The clinical significance of the frontal sinuses and their absence are also discussed.

    Foramen Jugulare: a Local Investigation and a Review of the Literature
    (2001) Aydinlioǧlu, A.; Yeşilyurt, H.; Diyarbakirli, S.; Erdem, S.; Daştan, A.
    The jugular foramen varies in size and shape. Because of the variations and the surrounding structures, successful surgery is difficult in this region. For this reason, numerous studies have investigated the detailed anatomy of the foramen. The purpose of the present study is to investigate the possible local variations of the foramen jugulare. In this work, Eastern Anatolian skulls were examined in order to investigate the local variety. Extracranial opening of the foramen was only measured in diameters as maximum anteroposterior (AP) and mediolateral diameter (ML) of both right and left foramen. The height of the jugular fossa was taken as the dome height (DH). The results were in mm (right-left) as: AP (12.2-10.9); ML (13.7-12.3); DH (14-13.7). The present study suggested that local differences of the jugular foramen in relative size and shape might occur. These differences are probably peculiar to the region or probably the result of some particular clinical situation.
