Magnetic Resonance Imaging (MRI) of the orbital and maxillofacial areas is performed to often evaluate facial fractures and trauma involving the orbit, which is the bony cavity in the skull that houses the globe of the eye (eyeball), the muscles that move the eye (the extraocular muscles), the lacrimal gland, and the blood vessels and nerves required to supply these structures.
Magnetic Resonance Imaging provides exceptionally detailed diagnostic images while avoiding radiation exposure. Patients generally find the exam easy to tolerate, as it is painless and not associated with known side effects.
When would I get a Orbital/Maxillofacial MRI?
Your medical provider may recommend an MRI involving the orbital and maxillofacial regions to be appropriate in order to:
- identify the cause of sudden vision loss
- evaluation of TMJ disorders
- detect the extent of orbital diseases and lesions
- confirm a diagnosis of acute demyelinating optic neuritis.
Orbital lesions form a wide range of pathologies that create challenges in diagnosis, management and treatment. MRI provides better lesion characterization. Especially in cases where history and clinical evaluation are insufficient, MRI plays a crucial role.
What Will I Experience During an MRI of the Orbital and Maxillofacial Region?
An MRI of the orbital and maxillofacial region focuses on the eyes, facial bones, sinuses, and surrounding soft tissues. During the scan, you will lie on your back with your head gently supported to minimize movement while high-resolution images are obtained.
The test is entirely noninvasive and typically painless. Because imaging around the face requires precision, remaining still is especially important. You may hear repetitive knocking or buzzing sounds as the scanner captures different image sequences — this is expected and does not indicate any discomfort.
In some cases, contrast material may be used to better visualize inflammation, masses, vascular structures, or nerve involvement. If needed, contrast is given through a small IV line. Most MRI of the orbital and maxillofacial exams are completed within 30 to 45 minutes, and you will be monitored and able to communicate with the technologist throughout the procedure.
