Abstract:
Objective:To explore the CT three-dimensional reconstruction in percutaneous balloon compression of the semilunar ganglion of trigeminal nerves.Methods:Thirty-one patients with trigeminal neuralgia, admitted to our hospital from May 2018 to August 2018, were treated by percutaneous balloon compression of the semilunar ganglion of trigeminal nerves. All patients underwent intraoperative mobile CT scan; the distance from the external aperture of foramen ovale to the petrous ridge, the angle from puncture needle and the petrous ridge, and the angle from puncture needle and the clivus were analyzed by three-dimensional reconstruction technology. Prognoses were recorded immediately after surgery and 10-12 months after follow-up.Results:The distance from the external aperture of foramen ovale to the petrous ridgea was (2.14±0.17) cm, ranged from 1.83 cm to 2.42 cm. The angle from puncture needle and the petrous ridge was (102.03±7.60)°, ranged from 91.00° to 116.00°. The angle from puncture needle to the clivus was (68.03±7.06)°, ranged from 52.00° to 80.00°. The puncture succeeded in all patients under the help of CT three-dimensional reconstruction. The volume of the inflated balloon ranged from 0.30 cm 3 to 0.47 cm 3 (averaged 0.42±0.05 cm 3). The compression time ranged from 3.00 min to 5.00 min (averaged 4.72±0.53 min). The incidence of diplopia was 3.23%, and the incidence of dry eyes/decreased corneal sensation was 12.90%. During the follow-up, one patient relapsed 10 months after surgery; the left patients recovered with disappeared complications. Conclusion:The CT 3D reconstruction can reduce the difficulty of ovale foramen puncture during operation, assist the judgment and adjustment of intraoperative balloon volume, and improve the surgical efficacy.
