Spinal cord cavities are mostly congenital brain physiological malformations secondary to subungual herniation of the cerebellum forming extrusion of the spinal cord and blocking the cerebrospinal fluid circulation leading to increased pressure in the central canal of the spinal cord forming a stage cavity if caused by encephalopathy pressure overload, injury to the spinal cord delayed spinal cord injury leading to spinal cord dysfunction, or unexplained encephalopathy to brain pressure overload affecting the spinal cord circulation secondary to the expansion of the central canal of the spinal cord. Good lifestyle habits are a good way to prevent spinal cord cavitation. Prevention of spinal cord cavity should pay attention to the following points: First, maintain an optimistic and happy mood Stronger long-term or repeated mental tension, anxiety, irritability, pessimism and other emotional changes can make the balance of cortical excitation and inhibition process is out of balance, so that the muscle jump aggravates, so that the development of myasthenia gravis. Second, a reasonable diet to maintain normal digestive function. Spinal cord cavitation myasthenia patients to maintain normal digestive function, reasonable deployment of dietary structure is the basis of recovery. Patients with spinal cord cavitation myasthenia require high-protein, high-energy dietary supplements to provide substances necessary for the reconstruction of nerve cells and skeletal muscle cells to enhance muscle strength and muscle growth. Early adopts high-protein, vitamin-rich, phospholipid-rich and trace element foods, and actively cooperates with medicinal diets, such as yam, coix seeds, lotus hearts, Chen Pi, prunus seeds, lily, etc., prohibits spicy foods, and abstains from smoking and alcohol. For patients in the middle and late stages, high protein, high nutrition, energy-rich semi-liquid and liquid food is the mainstay, and less and more meals are used to maintain the patient’s nutrition and water-electrolyte balance. Third, pay attention to the prevention of colds and infections spinal cavitation myasthenia gravis patients due to their own immune function is low, or there is some kind of immune deficiency, once the cold, the disease aggravates, the course of the disease is prolonged, myasthenia gravis, muscle jump aggravates, especially ball palsy patients prone to complications of pulmonary infection, if not timely prevention and control, the prognosis is poor, and even endanger the lives of patients. Gastroenteritis can lead to intestinal strain dysfunction, especially viral gastroenteritis has different degrees of damage to the anterior horn cells of the spinal cord, thus making patients with increased muscle jump, decreased muscle strength, recurrent or aggravated. Fourth, pay attention to joint diseases often combined with Charcot’s arthropathy (joint wear, atrophy and deformity, joint enlargement, increased mobility, friction sounds without pain during movement), scoliosis, bowed feet, skull base depression, hydrocephalus, etc. The cavity often involves the spinal nucleus of the trigeminal nerve, resulting in onion skin-like pain and temperature loss in the face, developing from the lateral side to the nasolabial region; involvement of the suspected nucleus causes dysphagia and choking; involvement of the nucleus of the hypoglossal nerve extensors and muscle bundle tremors; involvement of the facial nerve nucleus results in peripheral facial palsy; involvement of the vestibulocerebellar pathway results in vertigo, nystagmus and gait stability. Spinal cord cavitation is often combined with other congenital malformations, such as scoliosis or retrognathism, recessive spina bifida, cervico-occipital malformation, submicrocephalic tonsillar herniation, and bowed feet.
