Few studies have assessed the use of the frontal sinus cavities for sex differentiation. In this study, a new methodology was used to assess the reliability of CBCT images of the frontal sinus cavity for determining sex based on the sexual dimorphism found in this anatomical structure. The survey sample consisted of 130 scans that were reconstructed three-dimensionally. 3D images of the cavity volume in the frontal, lateral, and basal views were exported in TIFF. The following variables were measured in a second program: area, perimeter, bounding rectangle, ellipse fit, circularity, aspect ratio, roundness, solidity, and Feret's diameter...

We report a case of dural arteriovenous fistula at the left transverse sinus and sigmoid sinus(TS-dAVF), which was treated with transvenous embolization(TVE)by direct puncture of the superior sagittal sinus(SSS)under indocyanine green(ICG)fluoroscopic guidance. A 71-year-old woman presented with pulsatile tinnitus and progressive dementia. A left TS-dAVF with retrograde SSS and cortical venous reflux(Cognard type IIb)was demonstrated on cerebral angiography. The left internal jugular vein and distal portion of the right transverse sinus were occluded...

Orbital subperiosteal abscess (OSPA) secondary to paranasal sinus mucocele (PSM) is rare, and it may be misdiagnosed as PSM with orbital invasion or even as a malignant neoplasm. The present study explored the computed tomography (CT) and magnetic resonance imaging (MRI) features of OSPA. The cases of 13 patients with OSPA secondary to PSM were retrospectively reviewed. CT had been performed in 12, MRI in 7, and postcontrast MRI in 4. OSPA was revealed as a well-demarcated, spindle-shaped mass that was broad-based and located beneath the superior orbital wall (orbital roof) in 11 and at the medial wall in 2...

BACKGROUND: The endoscopic modified Lothrop (Draf-III) surgery has improved treatment of recalcitrant frontal sinus disease, with favorable safety and long-term results. However, the short-term clinical and quality-of-life morbidity after Draf-III relative to less-extensive procedures has yet to be investigated. OBJECTIVE: To evaluate the surgical and quality-of-life outcomes, including the burden of follow-up care, in patients who underwent endoscopic modified Lothrop (Draf-III), and compared these results with a less-extensive intervention, the endoscopic frontal sinusotomy (Draf-IIa)...

Mucormycosis of the frontal sinus are rarely seen in day to day clinical practice. Although this fungus is commonly found in the environment, the disease is usually prevented by the immune system and is hence rare. Well-recognized risk factors for the disease include diabetes mellitus, leukemia, aplastic anemia, myelodysplastic syndrome, blood dyscrasias, and immunosuppressive therapy in organ transplantation, renal disease, sepsis, and severe burns. The disease is primarily found in those who are immunocompromised, but it may also manifest in immuno competent persons...

OBJECTIVE: The objective of this article is to describe the CT appearance of the midfacial skeleton after surgical repair of posttraumatic Le Fort, nasoorbitoethmoidal (NOE), and frontal sinus fractures. Several of the more commonly encountered complications will also be described. CONCLUSION: Surgery after midfacial trauma is aimed at restoring both form and function. Knowledge of the principal tenets of Le Fort, NOE, and frontal sinus fracture repair is vital for radiologists to accurately assess the adequacy of treatment on postoperative CT and provide meaningful reports for the surgeon...

Primary frontal sinus lymphoma is a rare disease, with the presenting symptoms that are secondary to the tumor mass effect and often misleading. Here we describe the case of a 43-year-old male patient who presented with a 4-week history of a gradually enlarging painful diffuse swelling over the right frontal sinus region. We report the clinical presentation, differential diagnosis and treatment of the case. We also reviewed the available literature on the diffuse large B-cell lymphoma in the frontal sinus region...

The complications of sinusitis are essentially secondary to ethmoidal and frontal sinusitis, occurring in patients weakened, particularly in case of immunodeficiency or anatomical defects. The gravity is due to the risk of spreading infection in intracranial tissues and orbital cavity. The diagnosis is always to discuss any symptomatology resistant to treatment and the appearance of orbital or neurological signs. The scanner and MRI contribute greatly to the orientation and diagnostic evaluation of the extent of the lesions...

Development of dural arteriovenous fistula (dAVF) after cerebral venous sinus thrombosis (CVST) was very uncommon and for all these reported cases, the dAVF was a chronic complication. We present a case of acute development of dAVF after CVST. A 40-year-old female was admitted into our department with 2day's headache and vomiting for 9h. Head computed tomography (CT) scan showed only scattered minor hematomas over the right frontal lobe. Blood test indicated an elevated D-dimer. The patient experienced transient paralysis (Todd's paralysis) after intermittent focal epilepsy from day 3, which progressed into sustained epilepsy on day 6...

BACKGROUND: Facial or head pain is not an infrequent symptom among patients diagnosed with chronic rhinosinusitis (CRS), but few reports have investigated the pain in CRS, including the relationship between pain and sites of CRS. The aim of this study was to investigate whether pain is related to the location of lesions on computed tomography (CT) in CRS. METHODS: We analyzed 203 patients who underwent endoscopic sinus surgery (ESS) for 2 years. Patients were assessed using the questionnaires on pain, provided 1 day prior to the operation and 6 months post operation...

Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis. It is characterized by multiple xanthogranulomatous masses throughout the body, predominantly in the tibia. One of the characteristic radiological findings of the lesions associated with ECD is a "coated artery," which is often observed in the aorta. Although approximately one-fourth of ECD cases involve the central nervous system (CNS), an intracranial-coated artery has only been reported in four cases. We report a case of ECD that involves the CNS and has the unique appearance of a coated vertebral artery (VA)...

Osteomas are the most common benign tumours of the sinonasal tract. Even though their location in the sinuses is well known, turbinate osteomas are quite rare. We report one such case of a 26-year-old female who presented with neurological complaints of a seizure rather than nasal complaints. The cause of the seizure was found to be a small abscess in her frontal lobe, secondary to frontal sinusitis due to a bony hard nasal mass arising from the middle turbinate. She underwent endoscopic excision of the mass which was confirmed on histopathology as an osteoma...

In endoscopic sinus surgery (ESS) synechiae formation and ostial stenosis are frequently encountered. This is not uncommon after frontal recess and ostium interventions due to the narrow recess and difficult anatomy of the region. The goal of this study is to evaluate the efficacy of the new cross-linked hyaluronan gel-PureRegen(®) Gel Sinus-on wound healing and synechiae prevention in endoscopic frontal sinus surgery. The study consists of two groups of patients who underwent ESS, including frontal sinus surgery...

To date, most frontal mucoceles are treated endoscopically, provided that there is no major neo-osteogenesis and that the frontal sinus floor is wide enough to provide an adequate working space: the presence of a sinus wall dehiscence is not considered as a contraindication to an endoscopic approach. We report on a series of 37 patients presenting with frontal sinus mucoceles with posterior table erosion. Thirty-three (89.2%) had minimal erosion and/or a limited protrusion of the mucocele within the anterior cranial fossa on CT-scan, and were successfully operated on through an endoscopic approach...

Frontal sinus mucoceles are benign, pseudocystic lesion deriving from the obliteration of the sinus ostium, resulting in a continuous mucous accumulation. The growing process of a mucocele leads to a progressive enlargement of the sinus cavity, thickening and eroding its bony walls up to invading the surrounding tissues. The surgical procedure through an endoscopic endonasal approach is the current treatment option for such conditions, but in cases with an extensive bone erosion and intracranial or intraorbital extension, a transcranial approach should be preferred...
