Rinosinüzit Komplikasyonu: İnatçı Subperiosteal Apse

Apse Alignment of Narrow Eccentric Planetary Rings

The boundaries of the Uranian ǫ, α, and β rings can be fitted by Keplerian ellipses. The pair of ellipses that outline a given ring share a common line of apsides. Apse alignment is surprising because the quadrupole moment of Uranus induces differential precession. We propose that rigid precession is maintained by a balance of forces due to ring self-gravity, planetary oblateness, and interpart...

Endoscopic subperiosteal midface lift.

The author performs endoscopic midface lift via the subperiosteal dissection level using 2 approaches: gingival buccal sulcus and temporal. He describes his technique in detail, emphasizing recent changes. (Aesthetic Surg J 2002;22:477-480.).

Subperiosteal hematoma in multiple settings.

Most reports of orbital hemorrhage do not distinguish among intraconal, extraconal, and subperiosteal hemorrhages, although several reports describe isolated subperiosteal hematomas as a separate entity. We report 3 cases of subperiosteal hematoma with different etiologies but similar progression of signs and symptoms. Each patient presented with spontaneous proptosis, rarely caused by orbital ...

Subperiosteal giant-cell reparative granuloma.

We present a case of subperiosteal giant-cell reparative granuloma followed over six years showing the complete evolution from the early phase of subperiosteal haematoma to the end stage of an ossified haematoma. Such lesions, although they are histologically similar to true giant-cell tumours, can be distinguished by the patients' age, their location on the diaphysis, and by their radiological...
