Technical advances now allow implants to be placed when pneumatization of the sinus has left insufficient bone to engage an endosseus implant. Augmenting material, such as a mixture of resorbable hydroxylapatite and demineralized freeze-dried bone, is grafted into the sinus cavity. This creates a new alveolar ridge to support endosseous implants.

A 53-year-old Caucasian female presented to the Oral Medicine Department at the hospital of the University of Pennsylvania for consultation regarding facial pain. A panoramic radiograph revealed multilocular radiolucencies in the right articular eminence. A CT scan was then performed, and the radiolucencies were determined to be pneumatization of the articular eminence.

OBJECTIVE The aim of this study was to observe the relationship of the sphenoid sinus and posterior ethmoid cells with the optic nerve. MATERIAL AND METHODS 34 CT scans (68 sides) of paranasal sinuses of patients older than 18 years were retrospectively reviewed. Images were assessed in two planes--axial and coronal. We observed the position and relationship of the optic nerve to the posterio...

Many morphological features of the Pleistocene fossil hominin Homo neanderthalensis, including the reputed large size of its paranasal sinuses, have been interpreted as adaptations to extreme cold, as some Neanderthals lived in Europe during glacial periods. This interpretation of sinus evolution rests on two assumptions: that increased craniofacial pneumatization is an adaptation to lower ambi...

background sphenoid sinus is surrounded by many vital vascular and nervous structures. in more than 20% of patients with chronic sinusitis, involvement of sphenoid sinus has been observed. besides, sphenoid sinus is an appropriate route to access anterior and middle cranial fossa in surgery. therefore, it is important to have an adequate knowledge about the contents of sphenoid sinus and its pr...
