Medial orbital wall fracture with rectus entrapment
Archives of Otolaryngology (Chicago, Ill. : 1960)
|January 1, 1975
Summary
Medial orbital fractures can trap the medial rectus muscle, causing double vision. Surgical intervention is recommended for persistent symptoms or eye recession.
Area of Science:
- Ophthalmology
- Trauma Surgery
- Medical Imaging
Background:
- Medial orbital fractures are uncommon but can lead to significant complications.
- Medial rectus muscle entrapment is a known sequela, causing characteristic clinical signs.
Purpose of the Study:
- To report two cases of medial orbital fracture with medial rectus muscle entrapment.
- To review the existing literature on this specific type of orbital fracture.
- To highlight diagnostic and therapeutic strategies.
Main Methods:
- Case report presentation.
- Comprehensive literature review of medial orbital fractures and muscle entrapment.
- Clinical examination including forced duction testing.
- Radiographic imaging with a focus on hypocycloidal tomography.
Main Results:
- Two new cases of medial orbital fracture with medial rectus entrapment were identified.
- A review of the literature identified six previously reported cases.
- Clinical findings consistently included diplopia (double vision) with lateral gaze.
- Forced duction tests confirmed mechanical restriction of the medial rectus muscle.
- Hypocycloidal tomography proved effective for radiographic diagnosis.
Conclusions:
- Medial orbital fractures with medial rectus entrapment present with specific clinical and radiographic features.
- Prompt diagnosis and surgical management are crucial for favorable outcomes.
- Surgical therapy is indicated to resolve diplopia and/or enophthalmos.
