What passes through the cavernous sinus?
The internal carotid artery and the abducens nerve pass through the cavernous sinus. On its lateral wall from above downwards lie the oculomotor, trochlear and ophthalmic nerves (Fig. 7.60). The maxillary division of the trigeminal goes through the lower part of the lateral wall or just outside the sinus.
What does not pass through the cavernous sinus?
Trigeminal nerve Prior to entering the cavernous sinus, the proximal portion of the nerve lies in Meckel’s cave, where it forms the trigeminal ganglion. After leaving the cave, the mandibular division (CN V3) courses inferiorly to pass through foramen ovale (without entering the cavernous sinus).
Which nerves are affected in cavernous sinus thrombosis?
Cavernous sinus thrombosis is associated with palsies of cranial nerves III, IV, V and VI, producing loss of corneal reflexes, ophthalmoplegia and hypesthesia over the upper part of the face.
Which cranial nerves pass through cavernous sinus?
The nerves of the cavernous sinus are the oculomotor nerve (CN III), trochlear nerve (CN IV), ophthalmic nerve (V1), maxillary nerve (V2), abducens nerve (CN VI), and the sympathetic plexus around the internal carotid artery.
How does cavernous sinus thrombosis occur?
Cavernous sinus thrombosis is usually caused by a bacterial infection that spreads from another area of the face or skull. Many cases are the result of an infection of staphylococcal (staph) bacteria, which can cause: sinusitis – an infection of the small cavities behind the cheekbones and forehead.
How does infection spread from face to cavernous sinus?
This complex web of veins contains no valves; blood can flow in any direction depending on the prevailing pressure gradients. Since the cavernous sinuses receive blood via this distribution, infections of the face including the nose, tonsils, and orbits can spread easily by this route.
What are the signs of cavernous sinus thrombosis?
Symptoms of cavernous sinus thrombosis include:
- a sharp and severe headache, particularly around the eye.
- swelling and bulging of the eye(s) and the surrounding tissues.
- eye pain that’s often severe.
- double vision.
- a high temperature.
How do you rule out cavernous sinus thrombosis?
Doctors may order brain scans, including CT and MRI scans, to look for cavernous sinus thrombosis. They may also test blood or spinal fluid to check for signs of infection.
