Meckel's Cave Size Measured by Magnetic Resonance Imaging in the Prognosis of Percutaneous Balloon Compression for Trigeminal Neuralgia.
Percutaneous balloon compression (PBC) is a safe and effective method to treat trigeminal neuralgia. Despite it is known that intraoperative balloon volume is crucial in the prognosis of PBC patients and correlates with Meckel's cave (MC) size, it is a lack of objective and valid criteria for intraoperative balloon volume of PBC. ⋯ The equation [balloon volume (cm3) = 0.110 cm3 + 1.274*MC size] yields an appropriate value at which the patient has a low recurrence rate and a low degree of facial numbness. Preoperative measurement of MC size can be used to guide the intraoperative balloon volume and to predict the patient's prognosis.
