The foramen spinosum is located in the base of skull on the sphenoid bone, structure passing through it are middle meningeal artery and vein, the nervus spinosum. Total 125 skull were used for this study. The results were foramen spinosum found as round shape in 52%, oval shape in 42% and irregular in 6%. The maximum diameter of foramen spinosum was 2.92+0.65mm and 2.12+0.45mm was minimum in ma...

Sphenopalatine artery ligation (SPL) is a surgical remedy for severe epistaxis. This procedure requires extensive knowledge of the various anatomical variants. Its topographical anatomy varies and reliable landmark such as the crista ethmoidalis may be absent. These variations are crucial and they dictate the outcome of the surgery. We present a peculiar case of a postero-superiorly located var...

Learning Objectives: After reading this article, the participant should be able to: 1. Identify the surgical anatomy and approaches to the foramen magnum region. 2. Recall the transcondylar approach to foramen magnum meningiomas. 3. Describe the suboccipital approach to foramen magnum meningiomas. 4. Explain the postoperative care and complications related to surgical techniques offoramen magnu...

volving the jugular foramen is rare. It shows usually hypovascular lytic bony destruction of the jugular foramen (1). Hypervascular metastases such as those from renal and thyroid carcinoma may produce destructive vascular lesions similar to paragangliomas (2). The authors report a case of hypervascular metastasis from thyroid carcinoma in the jugular foramen simulating glomus jugulare tumor.

BACKGROUND One of the anatomic structures in the mental interforaminal area is the mandibular incisive canal (MIC). Using various manipulation tools in the digital system may affect the visibility of MIC. OBJECTIVES The purpose of this study was to assess the effect of inversion filter (IF) on the visibility of mandibular incisive canal in panoramic radiographs. PATIENTS AND METHODS In this...

The Reagan Administration’s aggressive efforts to deregulate the national economy touched off a sharp debate over the proper relationship between the White House and the federal bureaucracy—and that debate continues to this day. Peter Strauss’s foreword1 last year directly joined it by setting forth an elegant and incisive critique of the notion that the President should be empowered to act as ...

Foramen of mandible is the most important point considering the Halsted anesthesia. Position of this foramen seems to be stable, however there are lots of controversies regarded to its position. Based on the current literature authors revised datas from literature considering the location of the mandibular foramen.

AIM To determine the accuracy of locating the apical constriction using apex locators. METHODOLOGY Extracted teeth were micro-CT scanned preoperatively to localize the apical constriction. Electronic length measurements of 91 root canals were made using nine electronic apex locators (EAL) connected to a mounting model. Distances from the major foramen were recorded at each scale bar of the EA...

BACKGROUND The sphenopalatine foramen is located on the lateral nasal wall and has multiple variants and anatomic landmarks that are important to know to optimize RESULTS in the surgical management of posterior epistaxis. OBJECTIVE This study describes the endoscopic anatomy of the sphenopalatine foramen, related structures and anatomic variations in a Mexican population. METHODS We perform...

Objective The literature reports that the location of mental foramen shows differences among races. The aim of this study was to assess the mental foramen position in a sample of Lebanese population using cone-beam computed tomography (CBCT) technology. Materials and methods In this study, we investigated CBCT images of 50 fully dentate Lebanese adults (23 males and 27 females). We assessed t...
