For 150 years, the variable clinical appearance of dural sinus thrombosis has plagued clinicians. Computed tomography (CT) has alleviated much of the difficulty in making this diagnosis. A high density lesion in the involved sinus on precontrast scans and a filling defect in the sinus on postcontrast scans were the most frequently observed CT abnormalities in 12 patients with sinus thrombosis. ...

Inadequate bone height in the lateral part of the maxilla forms a contra-indication for implant surgery. This condition can be treated with an internal augmentation of the maxillary sinus floor. This sinus floor elevation, formerly called sinus lifting, consists of a surgical procedure in which a top hinge door in the lateral maxillary sinus wall is prepared and internally rotated to a horizont...

In this paper the authors reported 2 cases of Sinus Histiocy-tosis . The first , an 11 year s o1d gir1 with massive 1ymphadnopathy of 10 CM diameter and 3 months duration otherwise normal. Paraclinic exams wer normal including BM. Diagnosis was confirmed by cervical node biopsy. She was followed clinically and was cured in 8 months. The second case, a 6 years old boy with massive cervical lymph...

Frontal sinus infection after incorrect treatment of an opened frontal sinus may require extended approaches. This article aims to introduce modified cranialization technique and secondary cranioplasty for frontal sinus infection involving the frontal sinus outflow tract after craniotomy. Eight patients with delayed onset frontal sinus infection involving frontal outflow tract after craniotomy ...

OBJECTIVE To determine the efficacy of frontal sinus drillout surgery for the treatment of chronic frontal sinusitis. DESIGN Retrospective case-control study. Mean +/- SD follow-up was 4.1 +/- 1.53 years (range, 1.4-6.9 years). SETTING Academic medical center. PATIENTS One hundred consecutive patients with chronic sinusitis who underwent frontal sinus drillout surgery. Indications were fa...

Assessment of the maxillary sinus anatomy before sinus augmentation is important for avoiding surgical complications, because of the close anatomical relationship between the posterior maxillary teeth and the maxillary sinus. The posterior superior alveolar artery (PSAA) is the branch of the maxillary artery that supplies the lateral sinus wall and overlying membrane. We evaluated the location ...

The aim of this study was to evaluate the histopathological findings of unilateral paranasal sinus disease dominated by maxillary sinus opacification on routine non-contrast enhanced paranasal sinus CT. We performed a retrospective analysis of routine paranasal sinus CT conducted between March 2003 and April 2007. Unilateral maxillary sinus opacification (with or without ipsilateral ethmoid or ...

BACKGROUND Osteotome sinus floor elevation is a less invasive approach to augment an insufficient alveolar bone at the posterior maxilla for dental implantation. However, this approach has some limitations due to the lack of sinus lift tools available for clinical use and the small transcrestal access to the maxillary sinus floor. We recently invented shape-memory Ni/Ti alloy wire containing tu...

BACKGROUND AND PURPOSE The termination of the superficial middle cerebral vein is classically assimilated to the sphenoid portion of the sphenoparietal sinus. This notion has, however, been challenged in a sometimes confusing literature. The purpose of the present study was to evaluate the actual anatomic relationship existing between the sphenoparietal sinus and the superficial middle cerebral...

PURPOSE To delineate the relationship between the optic nerves and the posterior paranasal sinuses using CT data. METHODS Direct coronal sinus CT scans of 150 consecutive patients with chronic inflammatory sinus disease were reviewed by two radiologists. Axial oblique reconstructions along the course of the optic nerve were obtained for the first 100 patients. The direct relationship between ...
