BACKGROUND: The trans-frontal-sinus-subcranial approach (TFSSA) allows for direct exposure and removal of olfactory groove meningiomas (OGMs), without any brain retraction. Compared to other skull base approaches (like fronto-orbito-basal, transbasal, subcranial, fronto-orbito-zygomatic and one-and-half approach), it could offer the same advantages but it is less invasive. OBJECT: We report the results in a series of 21 consecutive patients harboring OGMs and operated through TFSSA, in order to propose a viable alternative approach...

Meningiomas originate in the central nervous system and are the most common intracranial benign tumor. However, although rarely, they can develop extracranially. Primary extracranial meningiomas are frequently misdiagnosed, resulting in inappropriate clinical management. The most common sites of extracranial meningiomas include the skull, scalp, orbit, nose, paranasal sinuses, middle ear, neck, and skin. A 77-year-old woman presented with a mass on her left eyebrow. Computed tomography revealed an enhancing soft tissue mass in the left frontal area...

The etiology of fractures of the maxillofacial skeleton varies among studies, with motor vehicle accidents and assaults oftentimes the most common. The number of males outnumbers females throughout most studies. Fractures of the zygoma, orbit, and mandible are usually cited as most common fracture types. This study examines a single center's experience with regards to etiology and distribution of fractures. A retrospective review of all radiologically confirmed facial fractures in a level 1 trauma center in an urban environment was performed for the years 2000 to 2012...

OBJECTIVES: The aim of this study was to perform a pioneering investigation into the incidence of pneumatization in human skulls. METHODS: A total of 93 human skulls (≥20 years of age, 69 males, 24 females) were included in the study. The skulls were scanned in a fixed position using cone beam computed tomography (CBCT). The pneumatized space parameters within the nasal septum - width, length, and height - were measured. RESULTS: Two types of finding were identified: (a) Pneumatization, named "sinus septi nasi" (SSN), and (b) "spongy bone" (SB)...

Sinus pericranii (SP) located in the superior eyelid is an unusual clinical presentation. Here, we report a case of 72-year-old woman with an unruptured cerebral aneurysm presented with an SP located in the left superior eyelid. The SP was found to have a dominant venous outflow from the bilateral frontal region with an arterialized blood flow pattern on color Doppler ultrasonography (CDUS). During the aneurysmal surgery, intraoperative monitoring of the dominant venous outflow with CDUS was useful for the prevention of venous outflow obstruction...

The location of the heart within the thorax varies significantly between individuals. The resultant diversity of the anatomical cardiac long axis, however, and its determinants, have yet to be systematically investigated. We enrolled 100 consecutive patients undergoing coronary arterial computed tomographic angiography, decomposing the vector of the anatomical cardiac long axis by projecting it to horizontal, frontal, and sagittal planes. The projected vectors on each plane were then converted into three rotation angles using coordinate transformation...

Metastases in the paranasal sinuses are rare; renal cell carcinoma is the most common cancer that metastasizes to this region. We present the case of a patient with a 4-month history of a rapidly growing mass of the nasal pyramid following a nasal trauma, associated with spontaneous epistaxis and multiple episodes of hematuria. Cranial CT scan and MRI showed an ethmoid mass extending to the choanal region, the right orbit, and the right frontal sinus with an initial intracranial extension. Patient underwent surgery with a trans-sinusal frontal approach using a bicoronal incision combined with an anterior midfacial degloving; histological exam was compatible with a metastasis of clear cell renal cell carcinoma...

Calculating attenuation correction for brain PET imaging rather than using CT presents opportunities for low radiation dose applications such as pediatric imaging and serial scans to monitor disease progression. Our goal is to evaluate the iterative time-of-flight based maximum-likelihood activity and attenuation correction factors estimation (MLACF) method for clinical FDG brain PET imaging. FDG PET/CT brain studies were performed in 57 patients using the Biograph mCT (Siemens) four-ring scanner. The time-of-flight PET sinograms were acquired using the standard clinical protocol consisting of a CT scan followed by 10 minutes of single-bed PET acquisition...

Farm workers are at increased risk for animal-inflicted head injuries that are associated with significant morbidity and occasionally may be fatal. These injuries may cause permanent eye damage with or without concomitant skull base fracture. Here, we present a male farmer who suffered a cow attack that resulted in perforating orbital injury with comminuted frontobasal cranial fracture caused by a cow's horn. The next day, the patient developed nasal and orbital cerebrospinal fluid (CSF) leak. Computed Tomography cisternography revealed CSF leakage to frontal and maxillary sinuses...

Malignancies of the paranasal sinuses and ventral skull base present unique challenges to physicians. A transfacial or craniofacial approach allows for wide, possibly en bloc resection and is ideal for tumors that involve surrounding soft tissue, the palate, the orbit, anterolateral frontal sinus, and lateral dura. Transfacial approaches include a lateral rhinotomy often combined with a medial, subtotal, or total maxillectomy. Reconstruction is most commonly performed with a pericranial flap to separate the intranasal and intracranial compartments...

The objective of this study was to determine the feasibility of trephination of the frontal sinus and injection of antifungal cream using a medical bone marrow drill in dogs. Results were compared with frontal sinus trephination using a standard surgical technique. Bilateral trephination of the frontal sinuses was carried out in the heads of 11 cadavers using a medical bone marrow drill and a surgical bone chuck. The time taken to carry out the procedure using both techniques was compared. Before and after injection of antifungal cream into the frontal sinuses, computed-tomography (CT) scanning was done to assess for iatrogenic trauma and to determine the degree to which the sinuses were filled with each technique and evaluate the diffusion of the cream into the nasal cavity of each dog...

The aim of the study was to correlate several studies dating from 1997 to 2015 to identify the most effective treatments for mucocele in the frontal sinus (with/without other paranasal sinuses), considering successful outcomes and recurrence. We aimed to conduct a literature review for articles published between 1997 and 2015. For this, we accessed articles in the SciELO database, as well as LILACS, PubMed, and Google Scholar databases. Were identified 32 work-related injuries in the paranasal sinuses; 2 of these were not related to mucoceles or mucopyocele, 4 had no relation to the frontal sinus, 9 were related to the frontal sinus and other paranasal sinuses, 4 were related to mucocele associated with other sinuses, and 13 involved only the frontal sinus...

INTRODUCTION: Extended endoscopic frontal sinusotomy is often required for surgical management of anterior skull base pathology. Such approaches are necessary for access to pathology and maintenance of postoperative frontal sinus outflow tract drainage. Cold steel instrumentation and endoscopic high-speed microdrills are typically used for bony removal during extended frontal sinus approaches but are associated with certain drawbacks, such as thermal injury and obscuration of the surgical field with bone dust...

The frontal sinus outflow pathway is complex and can be influenced by the configuration of the uncinate process (UP). The UP can attach superior to the lamina papyracea, skull base, and middle turbinate. The factors associated with superior attachment remain unclear. This study analyzed the relationships between different types of superior UP attachment and characteristics of the surrounding structures including the agger nasi cell, skull base, and middle turbinate. This retrospective study utilized computed tomography images of 836 sides with identifiable sinus structure from 434 Taiwanese patients...
