This review gives detail information about the mental foramen location, shape, size and numbers and its variation between races. Studies have shown that there are variations in the position of mental foramen in different populations. It may lie between the apices of premolars, below the apex of first or second premolars. This variations mandate accurate detection of foramen during examination a...

AIM The objectives were to study the morphology of the foramen magnum in dry skulls and to evaluate its antero-posterior diameter, transverse diameter and the foramen magnum index. MATERIAL AND METHODS The foramen magna of 53 dry human cadaver skulls that were obtained from the neuroanatomy laboratory were examined. Different shapes of the foramen magnum were macroscopically n...

BACKGROUND AND PURPOSE A patent foramen ovale has been reported to be significantly more frequent in young stroke patients than in matched control subjects, and paradoxical embolism has been suggested as the main mechanism of stroke in this situation. The present study was designed to test this hypothesis. METHODS Sixty-eight consecutive patients under 55 years of age presenting with an ische...

Evidence shows a clear racial variation in the position of the mental foramen. Therefore, detailed knowledge of the morphometry of the mental foramen in different populations is essential in clinical dentistry when administering regional anesthesia, and performing peripheral surgery in the mental region of the mandible. The goal of this study was to elucidate the morphological features and prec...

The ramus of mandible presents on its medial surface a little above its centre an irregular foramen called the mandibular foramen. This foramen is guarded by a thin sharp tongue shaped projection in its proximity called the lingula. This foramen transmits the inferior alveolar nerve and the corresponding artery to the mandibular canal (Grays) [1]. Here in , the nerve supplies the pulps of all t...

Knowledge of the position of the mental foramen is important both when administering regional anesthesia and performing periapical surgery in the mental region of the mandible. This study determines the position of the mental foramen in a selected Malay population. One hundred and sixty nine panoramic radiographs of Malay patients retrieved from a minor oral surgery waiting list were selected t...

The purpose of this study was to investigate the position of the mandibular foramen from deciduous (Hellman's stage IIA) to early permanent dentition (Hellman's stage IVA). Panoramic radiographs of 311 Taiwanese children were used. The results revealed that the distances between the mandibular foramen and ramus anterior plane were greater than those between the mandibular foramen and ramus post...

The jugular foramen at the base of the skull varies in shape and size the foramen lies at the petrous part of temporal bone and behind by the occipital bone. It’s irregular in shape. Usually the right foramen is larger than the left. The variation in the foramen is observed in different racial group and sexes. The shape and size of foramen is inversely related to size of sigmoid sinus. Petrosal...

Human skull is shown to exhibit numerous sexually dimorphic traits. Estimation of sex is a challenging task especially when a part of skull is brought for medicolegal investigation. The present research was planned to evaluate the sexing potential of the dimensions of foramen magnum in forensic identification by craniometric analysis. Length and breadth of the foramen magnum was measured using ...
