BACKGROUND AND PURPOSE The sphenoid sinus is rarely implicated as a site of spontaneous CSF fistula. We undertook this study to evaluate the potential etiopathogenesis of spontaneous CSF fistula involving the sphenoid sinus and to review the imaging findings. METHODS We retrospectively reviewed the imaging findings of 145 cases of CSF fistula from our departmental archives (August 1995 throug...

Patterns of postcranial skeletal pneumatization (PSP) indicate that pterosaurs possessed components of a bird-like respiratory system, including a series of ventilatory air-sacs. However, the presence of PSP in the oldest known pterosaurs has not been unambiguously demonstrated by previous studies. Here we provide the first unequivocal documentation of PSP in Late Triassic and earliest Jurassic...

We describe a case of hemitrophy in a 12-year-old child presenting with seizures, hemiplegia and mental retardation. Hemiatrophy of one cerebral hemisphere is not frequently encountered in clinical practice. When this develops early in life (during the first two years), certain cranial changes like ipsilateral hypertrophy of the skull and sinuses occur. Asymmetry of cerebral hemispheric growth ...

The placement of dental implants in the distal edentulous maxillary region is challenging due to the significant resorption following tooth extraction and the pneumatization of the maxillary sinus (Tadjoedin et al., 2003). Maxillary sinus augmentation is a well-established procedure for functional rehabilitation of partially or completely edentulous patients, as demonstrated by Boyne and James ...
