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.
Local Differences in the Position of the Mental Foramen
(2008) Yeşilyurt, H.; Aydinlioǧlu, A.; Kavakli, A.; Ekinci, N.; Eroǧlu, C.; Hacialioǧullari, M.; Diyarbakirli, S.
The mental foramen has been reported to vary in position in different ethnic groups. Repeated failures during injections and operative procedures involving the mental foramen suggest the presence of local differences in a given population. The aim of the present study was to investigate possible local differences of the mental foramen in Eastern Anatolian individuals in the Turkish population. The present investigation is based on the examination of 70 adult mandibles. The study consisted of three measurements, to include the relations of the mental foramen to the following: 1) the lower teeth; 2) the body of mandible; 3) the mandibular symphysis and posterior border of the remus of the mandible. The most common position of the foramen was in line with the longitudinal axis of the second premolar tooth (relation IV), at the midpoint of the mandibular body height and at 1/3.5 of the distance from the mandibular symphysis to the posterior border of the ramus. Local differences of the mental foramen may occur in a population. Prior to surgery knowledge of the most common location of the foramen peculiar to a local population may enable effective mental block anaesthesia to be provided. Copyright © 2008 Via Medica.
The Relationship of Sex Differences To the Anatomy of the Corpus Callosum in the Living Human Being
(Turkish Neurosurgical Society, 1996) Aydinlioglu, A.; Diyarbakirli, S.; Yuceer, N.; Keles, P.; Unal, O.; Erdogan, A.R.
The area of the midsagittal section of the corpus callosum, particularly in the region of the splenium was found to be greater in women than in men. The magnetic resonance imaging of seventy adults was examined and showed the same association previously observed, between sex differences and area of the corpus callosum and its splenium. The quantitative results supported a relationship between variations in callosal anatomy and sex differences in human beings. Findings are discussed in the light of the related literature.
Variations of Abductor Pollicis Longus and Extensor Pollicis Brevis Muscles: Surgical Significance
(1998) Aydinlioǧlu, A.; Tosun, N.; Keles, P.; Akpinar, F.; Diyarbakirli, S.
To investigate variations of the abductor pollicis longus and the extensor pollicis brevis muscles, an anatomic study was performed on 15 cadaver forearms. Some variations were observed as reported in previous studies. An unusual insertion of the abductor pollicis longus muscle and the extensor pollicis brevis muscle also was encountered during the dissection. Both tendons of these muscles were found to have inserted into the inferior side of the base of the first metcarpal bone together, instead of dorsal side. Our study suggested that the extensor pollicis brevis muscle and the abductor pollicis longus muscle differentiate from a common muscle.
