Abstract：ObjectiveTo investigate therelationship between Meckel'scavityshape，baloonshapeand intracapsular pressure during percutaneous baloon compresion（PBC）.MethodsFifty-eight patientswith typical trigeminal neuralgia who underwent PBC in Afiliated University from September 2O20 February 2022 were analyzed retrospectively.Magnetic resonance imaging （MRI）3D-FIESTA thin-layer scanning sequence reconstruction was performed before operation analyze thesagittal features Meckel’s cave.The pressure when ballon“pear shaped” forming wasrecorded continuously during operation，and the baloon height/length ratio was measured.Therelationship betweenthe shape the Meckel's cave cavity，theshapetheballoon，andthe internalpressurewithinthe ballonwasanalyzedthrough multiple parameters.ResultsThepain 57 patients was relieved immediatelyafter operation，andtheefective rate was 98.28% .Recurrence occurred in 2 cases and the recurrence rate was 3.5% with the 7.5 months median following time.Classification Meckel’s cave on magnetic resonance imaging showed the clubbing type accounted for （31.1%） ，oval type（58.6%），flat type（10.3%） .Theintracavitarypressurewas significantlynegativelycorrelated withtheheight/lengthratio Meckel’scave.There wasnostatisticallysignificant differencebetween theheight/ lengthratiothebaloonandthat Meckel’scave.ConclusionsPreoperativeevaluation thesagital shape Meckel's caveis conducted using 3D-FIESTAthin-slice MRIreconstruction.The results indicateanegative correlation between intracavitarypressureandthe height/lengthratioMeckel’scave.However，thecorrelation between the“pear shaped”balloon formationand the sagittal shape Meckel's cave is relatively low.
