To examine a relation of angles among the coronal, sagittal and lambdoid sutures to the size of the calvaria as well as to the remains of the metopic suture, 158 adult Japanese calvae or calottes were observed. The calvae used consisted of four groups: group M composed of 74 male calvae without the metopic suture; group F, of 41 female calvae without the same suture; group Un, of 27 sex-unknown...

The ‘Wormian bones’ or ‘sutural bones’ are small bones found at the sutures of the skull. They are unnamed bones because they vary from person to person in number and shape. They are commonly found in relation to the frontal and occipital bones. It is important to know about these bones because they can mislead in the diagnosis of fracture of skull bones. We saw a series of sutural bones in the...

Background: Petro-clival, clival and spheno-petro-clival tumours are still a neurosurgical challenge. Usually, the classical skull base transpetrous approaches are employed, although they are burdened by an important rate of morbidity, and a very low rate of radical removal is reported. Objectives: We present our indications and results with minimally invasive transnasal and transoral approache...

occipital neuralgia is a condition manifested by chronic occipital headaches and is thought to be caused by irritation or trauma to the greater occipital nerve (gon). treatment for occipital neuralgia includes medications, nerve blocks, and pulsed radiofrequency ablation (prfa). landmark-guided gon blocks are the mainstay in both the diagnosis and treatment of occipital neuralgia. ultrasound is...

Objective Compare nasal endoscopy with 3 mm versus conventional 4 mm rigid 30° endoscopes for visualization, patient comfort, and examiner ease. Methods Ten adults with no previous sinus surgery underwent bilateral nasal endoscopy with both 4 mm and 3 mm endoscopes (resulting in 20 paired nasal endoscopies). Visualization, patient discomfort and examiner's difficulty were assessed with every ...

Epidural hematoma of the posterior cranial fossa (EHPCF) is a rare complication in head injuries. Furthermore, nonspecific clinical signs and the rare occurrence of this lesion in craniocerebral injuries make the establishment of a diagnosis more difficult. The aim of the paper is to point to the advantages of early diagnosis. During the 1982-2008 period, 18 patients with EHPCF were operated on...

Introduction Frontal bone of the skull develops in two halves during the fetal life separated by the metopic suture. The suture normally disappears soon after the birth [1]. The persistent complete metopic suture extending from the nasion to bregma is called metopism [2]. Lambda represent the meeting point of the sagittal and lambdoid suture. It represents the site of posterior median fontanel ...
