Intracranial volume before and after surgical treatment for isolated metopic synostosis.

Metopic synostosis results in a keel-shaped forehead, hypotelorism, and an increased interparietal width. This study aimed to measure the frontal and total intracranial volume in patients with metopic synostosis before and after surgery and to compare the effect of 2 different operation methods. All patients operated for isolated metopic synostosis between 2002 and 2008 at Sahlgrenska University Hospital who had undergone preoperative and/or postoperative computed tomographic examination (at 3 y of age) were included. The patients were grouped according to operation method: (1) forehead remode

Carotid artery dissection associated with an elongated hyoid bone.

A 36-year-old man presented with acute cerebral infarction in the right frontal lobe associated with right internal carotid artery dissection (CAD). Enhanced computed tomography revealed right greater horn of the hyoid bone in close proximity to the right internal carotid artery (ICA). It was speculated that mechanical compression of the internal carotid artery by the hyoid bone induced by neck rotation was related to ICA dissection. Greater knowledge of the association between the hyoid bone and the CAD will lead to increased awareness and appropriate diagnosis.

Ten of 14 patients with lambdoid deformities had bilateral enlargement of the subarachnoid spaces suggesting brain atrophy and an underlying motor delay accounting for the position-induced skull changes. The findings suggest that focal hydrodynamic …

Prevalence of agenesis of frontal sinus in human skulls with metopism.

BACKGROUND: The frontal bone is an anatomical structure of the skull separated by the metopic suture in the childhood. The scientific literature indicates that metopic suture consolidates with closure in the early stages of life. Metopism is the term used to describe a metopic suture that persists up to the adulthood. Persistent metopic suture is associated potentially with the agenesis of the frontal sinus. AIM: To investigate the prevalence of absent frontal sinuses in dry skulls with metopism. MATERIALS AND METHODS: The present study was performed after the approval of the local Committee…

Frontal Sinus Epidermoid Cyst: A Rare Clinical Entity With Diagnostic Challenges and Surgical Considerations-A Case Report.

Epidermoid cysts are rare lesions in the frontal sinus, often presenting with nonspecific symptoms such as headaches and localized swelling. These factors can complicate diagnosis and management. This report describes an epidermoid cyst that was initially suspected to be a malignant mass due to the erosion of the anterior wall and the sclerotic nature of the lateral wall, which had extended toward the orbit. This conclusion is supported by the observation that its pressure has pushed the eye downward, suggesting a primary origin in the frontal sinus rather than the orbit. We present a case of

A simple aesthetic approach for correction of frontal sinus fracture.

PURPOSE: Frontal sinus fracture management remains controversial and involves preserving function whenever possible or obliterating the sinu … as used to apply force in the opposite vector. One titanium screw was also fixed to the firm normal frontal bone, and the reduction was conducted by observing the C-arm until the fractured fragment reached the height of the normal side. RESULTS: No patients showed any recurrent displacement or infection during the follow-up period, nor did any patient complai …

Assessment of Frontal Sinus Volume and Cranial Base Length Based on Different Vertical Skeletal Patterns: A Cone Beam Computed Tomographic Study.

Introduction Evaluating craniofacial growth is an essential component of orthodontic treatment, and it is assessed by examining the cranial base. The anterior cranial base is regarded as a stable structure, and the frontal sinus is also recognised as a contributing component in the formation of the cranial base. The frontal sinus, a cavity present in the frontal bone, displays variation in both size and shape and has an impact on the overall structure of the skull and face. This study aims to evaluate the impact of vertical skeletal pattern and gender on the volume of the frontal sinus. Materi…

Radiologic staging system for allergic fungal rhinosinusitis (AFRS).

OBJECTIVES: 1) Develop an objective method for quantifying radiologic bone erosion in allergic fungal rhinosinusitis (AFRS); and 2) assess the utility of the new CT scan staging system in differentiating AFRS patient groups. METHODS: Patients from two tertiary care rhinology practices with AFRS and available CT scans (1999-2007) were included for review by trained graders. The following novel assessment scale was used: Each paranasal sinus wall with expansion/erosion was scored 1 point, with maximum 3 points possible for each frontal sinus, 2 points for each ethmoid complex, 3 points for each

Axial and frontal X-ray fluoroscopy technique of the sustentaculum tali can improve the accuracy of sustentacular screw placement.

INTRODUCTION: Calcaneal fractures, especially those involving the articular surface, should be anatomically reduced as much as possible. Fixing the fracture by placing a screw into the sustentaculum tali from the lateral side of the calcaneus is generally considered to be the key to successful surgery. However, due to the limited visibility during surgery, it is not easy to place screws into the sustentaculum tali accurately. The purpose of this study was to explore a new fluoroscopy method for the sustentaculum tali and verify the value of this method in improving screw placement accuracy. M

Unilateral exophthalmos caused by an anterior ethmoidal meningoencephalocele.

A case of unilateral enophthalmos in a 1-year-old child is presented. This was caused by a meningoencephalocele that originated in the anterior cranial fossa and protruded into the orbit through a bony defect at the junction of the frontal and ethmoid bones at the site of the anterior ethmoid canal. This meningoencephalocele was reduced, and the dura was repaired with a temporalis fascia graft. A split calvarial bone graft was inserted into the floor of the orbit, and lateral canthal ligament elevation completed the operative correction.

Research on skull trauma biomechanical stress distribution in case of dental implants existence.

BACKGROUND: When the jaw bone is subjected to an external force, the stress is transmitted from the force point along the alveolar bone to the skull and skull base. In the case of a dental implant, the stress distribution is mainly dependent on the implant position, type, and mechanical properties. OBJECTIVE: To investigate the dental implant position influence on the stress distribution and transmission in case of facial frontal trauma. Furthermore, the correlation between facial trauma and skull trauma in the case of a dental implant exists. METHODS: In this study, a Finite Element Method

Frequency of hyperostosis frontalis interna in patients with active acromegaly: is there a possible role of GH excess or hyperprolactinemia in its etiopathogenesis?

PURPOSE: Acromegaly is characterized by bone changes due to excessive growth hormone (GH) secretion. Hyperostosis frontalis interna (HFI) is described as an overgrowth in the inner plate of the frontal bone. An increased incidence of HFI has been reported in patients with acromegaly. Since the etiology of HFI is poorly understood, we have analyzed whether there is a relationship between the hormonal and metabolic status of patients with acromegaly (with or without hyperprolactinemia) and the pathogenesis of HFI. METHODS: Forty-five patients with acromegaly and two control groups consisting of…
