Orbital fracture evaluation by coronal computed tomography
American Journal of Ophthalmology
|May 1, 1978
Summary
Coronal computed tomography (CT) offers detailed orbital imaging, aiding in diagnosing orbital floor fractures and detecting muscle entrapment. This advanced CT technique improves visualization of bone fragments and soft tissues for better surgical planning.
Area of Science:
- Radiology
- Ophthalmology
- Medical Imaging
Background:
- Coronal computed tomography (CT) provides orbital scans similar to Caldwell-view x-rays.
- It allows simultaneous visualization of orbital walls, soft tissues, and extraocular muscles.
Observation:
- The study examined patients with radiographically confirmed orbital floor fractures.
- Three detailed cases included linear, depressed, and comminuted fractures.
- Coronal CT identified inferior rectus muscle entrapment in two patients, confirmed surgically.
Findings:
- Coronal CT offers superior visualization of bone fragments compared to conventional polytomes.
- It effectively detects extraocular muscle entrapment in orbital floor fractures.
- The technique aids in identifying intraorbital foreign bodies and displaced bone fragments.
Implications:
- Coronal CT is a valuable tool for diagnosing and managing orbital floor fractures.
- It enhances the detection of complications like muscle entrapment.
- This imaging modality improves pre-surgical assessment and planning for orbital trauma.
