The changes in intracranial pressure can timely and accurately indicate the physiological and pathological changes. Therefore, scientific and reasonable intracranial pressure monitoring can provide an effective basis for the prevention and treatment of craniocerebral diseases. Two main methods for intracranial pressure monitoring are invasive intracranial pressure monitoring and noninvasive intracranial pressure monitoring. Invasive intracranial pressure monitoring has been regarded as the golden standard due to its high accuracy, but its application is limited for its high cost and many complications. To seek a cheap, reliable, widely applicable intracranial pressure monitoring method with few complications, scientific researchers and clinical workers have worked hard for various noninvasive intracranial pressure monitoring methods. This paper briefly reviews the methods, mechanisms, current situation, advantages and disadvantages of related products and research trends of many noninvasive intracranial pressure monitoring ways developed in recent years.
