Abstract:
Objective:To investigate the influences of morphological characteristics of skull base ovale foramen in the puncture difficulty of percutaneous balloon compression (PBC), surgical efficacy and postoperative complications in patients with idiopathic trigeminal neuralgia (ITN).Methods:One hundred and twenty-seven patients with ITN, admitted to our hospital from January 2020 to January 2021, were collected. Dyna-CT three-dimensional imaging of the oval foramen at the skull base and PBC treatment were performed on the included patients, and the morphological data of the oval foramen were measured. Numeric Rating Scale (NRS) was used to assess pain degrees before and after surgery. The differences of cross-sectional area and exposure Angle, puncture difficulty and time, NRS scores before and after surgery and incidence of complications were compared in patients with ovale foramen at different forms. The correlations of puncture time with puncture difficulty and cross-sectional area of ovale foramen in skull base were analyzed.Results:The foramen ovale in skull base of 127 patients included standard oval shape ( n=82), almond shape ( n=9), narrow and long shape ( n=13), fissure shape ( n=8) and irregular shape ( n=15). Different morphological characteristics of the skull base ovale foramen could lead to significant differences in the difficulty of puncture, exposure angle, cross-sectional area and puncture time ( P<0.05). Puncture time was positively correlated with puncture difficulty and cross-sectional area ( r=0.359, P<0.001; r=0.280, P=0.007). The patients with skull base ovale foramen of different forms showed no significant differences in the differences of NRS scores before and after PBC and occurrence of postoperative complications ( P>0.05). Conclusion:Dyna-CT three-dimensional imaging can visually display the morphological characteristics of the oval foramen at the skull base; this technique can be used to guide the puncture of the oval foramen and effectively evaluate the difficulty of puncture in PBC, but it does not affect the postoperative pain improvement and complication incidences.
