Frontal sensory loss

Introduction The cavernous sinus segment of the internal carotid artery aneurysm can be divided into three groups: the anterior, middle and posterior segments. The anterior segment of the aneurysm produces ocular branch symptoms, which is characterized by a loss of sensation in the frontal area and a slow corneal reflex. The reason is not very clear. Arterial wall has congenital factors, arteriosclerosis, infection or trauma, and the impact of blood flow is the cause of aneurysm formation. The cause of aneurysm is not well understood. Arterial wall has congenital factors, arteriosclerosis, infection or trauma, and the impact of blood flow is the cause of aneurysm formation. Aneurysm (an aneurysm is a permanent swelling of the arteries due to weak arterial wall, aneurysms can be formed anywhere, but the most common and troublesome place for aneurysms is in the cerebral arteries, the aorta, and The cause of the disease is that the blood pumped from the heart is taken to the other part of the body. The cause of the disease is not well understood. Arterial wall has congenital factors, arteriosclerosis, infection or trauma, and the impact of blood flow is the cause of aneurysm formation.

The cavernous sinus segment of the internal carotid artery aneurysm can be divided into three groups: the anterior, middle and posterior segments. The anterior segment of the aneurysm produces ocular branch symptoms, which is characterized by a loss of sensation in the frontal area and a slow corneal reflex. The middle segment of the aneurysm produces symptoms of the ocular branch and the maxillary branch. In addition to the symptoms of the eye branch, there is a facial sensation of the cheek. The posterior segment produces a complete trigeminal nerve manifestation of the mandibular sacral tendon to the diseased side, and the masticatory muscles of the diseased side are weak or atrophied. Wait.

Differential diagnosis

Differential diagnosis of sensation loss in the frontal area:

1. Deep sensory disorder: deep sensation refers to muscle and joint position, movement, and vibration. If the nerve fibers or brain-sensing central lesions that transmit deep sensations are present, muscle and joint positional sensation, motor sensation, and vibration dysfunction are deep sensory disturbances.

2, sensory impairment: the feeling is the direct response of various receptors to the body's various stimuli in the human brain. Sensory disturbance is one of the common symptoms in nervous system diseases.
