Augmentation of the maxillary sinus when severe atrophy and/or pneumatization has occurred results in minimal crestal height that will not allow simultaneous implant placement been a clinical challenge. The lateral augmentation approach traditionally utilized these situations, but there are known complications such as membrane tears and increased post-operative issues follow use this technique....
BACKGROUND Fronto-orbital advancement for nonsyndromic craniosynostosis has been thought to injure frontal sinus buds, lead to chronic sinus disease, and influence final forehead shape. This study investigates the effect of fronto-orbital advancement in infancy on subsequent frontal sinus volume, morphology, and disease. METHODS The authors conducted a retrospective review of nonsyndromic cra...
OBJECTIVES In this study, we used computed tomography measurements to investigate the feasibility of nasoseptal flap reconstruction of sellar defects in children, and we reviewed our institutional experience with the procedure. STUDY DESIGN Cross-sectional and case series. SETTING Pediatric tertiary care facility. METHODS We obtained 10 normal maxillofacial scans for each year of age from...
Detailed anatomical knowledge of the variability in the drainage pathway in relation to the frontal sinus is a prerequisite for successful sinus surgery. We studied 32 mid-sagittal cadaveric heads and recorded the following parameters: drainage site of the sinus in relation to the uncinate process, attachment of the uncinate process, pneumatization of the agger nasi, and morphometric measuremen...
The rebbachisaurid sauropod Tataouinea hannibalis represents the first articulated dinosaur skeleton from Tunisia and one of the best preserved in northern Africa. The type specimen was collected from the lower Albian, fluvio-estuarine deposits of the Ain el Guettar Formation (southern Tunisia). We present detailed analyses on the sedimentology and facies distribution at the main quarry and a r...
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 ...
Abstract Background Surgery is often indicated for definitive biopsy or as the primary treatment modality pediatric skull base lesions. Traditionally, open surgical approaches were utilized to address pathology. However recently, expanded endoscopic sinus surgery has been a minimally invasive approach addressing pathology in population. Purpose This review provides an overview of current litera...
