purpose: in this study we aimed to investigate the benefits of far-lateral approach without partial condylectomy in patients with foramen magnum meningiomas over surgical approach with condylectomy. methods: from 1980 to 2011, a total of 17 patients with foramen magnum meningiomas were treated surgically via far-lateral approach without condylectomy. the follow up period of this study was 6 to ...

BACKGROUND Information on the position of the mental foramen is important for dental surgeons. Variations in its position can be a cause of complications during local anesthesia or surgical procedures. The usual position of the mental foramen in an Iranian population has not been previously reported. AIMS The purpose of this study was to determine the most common location of the mental forame...

PURPOSE The purpose of this study was to improve the treatment methods for the mental foramen by comparing the directly measured values with the radiographic measured values. MATERIALS AND METHODS One hundred and twelve mental foramina (72 males, 40 females) that were exposed during the operation were examined. The patients' age ranged from 12 to 69 years, with a mean age of 41.8 years. All p...

Since instrumentation of the apical foramen has been suggested for cleaning and disinfection of the cemental canal, selection of the file size and position of the apical foramen have challenging steps. This study analyzed the influence of apical foramen lateral opening and file size can exert on cemental canal instrumentation. Thirty-four human maxillary central incisors were divided in two gro...

The mental foramen can be found in various locations, ranging from the root of the first lower premolar to the roots of the first molar. The anterior loop is described as the mental canal, which rises from the mandibular canal and runs outward, upward, and backward to open at the mental foramen. The knowledge of the location of the mental foramen and the existence of an anterior loop is importa...

The aim of the study is toreview the anatomical variations of supraorbital, Infraorbital and mental foramen related to gender and side in the dry skull. From our review, we found that supraorbital foramen lies 23.9mm right and 25.6mm left from the nasion approximately. Similarly we found that Infraorbital foramen lies in the maxillary bone lower to the edge of the orbital canal and it is bilate...

aneurysmal bone cyst (abc) is an expansile bone lesion that usually involves the long bones. skull base involvement is rare. hereby, we describe a 17-year-old man with hoarseness, facial asymmetry, left sided sensorineural hearing loss and left jugular foramen syndrome. ct scan and mri showed a skull base mass that was confirmed as abc in histopathology. the case was unusual and interesting due...

Background: The intermental foramina distance varies between ethnicities, according to an OPG (orthopantomogram), which is a form of dental x-ray. mandibular foramen has bony canal developed in the mandible at two independent anatomies and its rim 'v' shaped, that was common where groove separating anterior posterior parts horizontally orientated oval shaped rim. placement by ethnicity; always ...

Background. Mental foramen is important in surgical operations of premolars because it transfers the mental nerves and vessels. This study evaluated the variations of mental foramen by cone-beam computed tomography among a selected Iranian population. Materials and Methods. A total number of 180 cone-beam computed tomography projections were analyzed in terms of shape, size, direction, and hori...

A panoramic radiographic study was carried out on 404 dentate Saudi Arabians, to locate positions of the mental foramen. Results show that 83.7% of the mental foramen locations occurred in the interdental space between the mandibular premolars and apical to the mandibular second premolar. 9.35% occurred posterior to the mandibular second premolar, and 6.95% occurred apical/anterior to the mandi...
