C.T. demonstration of metastatic anaerobic orbital abscess
1Department of Otolaryngology, Soroka University Hospital, Beer-Sheva, Israel.
Abstract:
Orbital abscess of rhinosinogenic origin may develop, either by contiguous spread of the infection or by a thrombophlebitic process. While destruction of the bony walls of the paranasal sinus occurs in propagation of the infection by tissue continuity, haematogenous spread may take place through intact bone. Computed tomography demonstrates the status of the bony partitions shared by the orbit and paranasal sinuses, and the source of the orbital sepsis, thereby influencing the therapeutic approach.
Insights
Rhinosinogenic orbital abscesses can spread through direct contact or blood clots. Computed tomography (CT) is crucial for identifying the infection source and guiding treatment for orbital sepsis.
Area of Science:
- Otolaryngology
- Ophthalmology
- Radiology
Background:
- Orbital abscesses of rhinosinogenic origin are serious infections.
- Infection can spread via contiguous tissue or thrombophlebitic processes.
- Bone destruction may occur with direct spread, while hematogenous spread can bypass intact bone.
