Fibrin glue provides a superior watertight dural closure after transoral-transclival surgery compared to sutures or laser welding. This technique effectively prevents cerebrospinal fluid leaks, meningitis, and abscesses in canine models.

Area of Science:

  • Neurosurgery
  • Biomaterials Science

Background:

  • Transoral-transclival operations for craniocervical junction lesions pose challenges for watertight dural closure.
  • Cerebrospinal fluid (CSF) fistulas, meningitis, and abscesses are significant risks associated with inadequate dural closure, leading to high morbidity and mortality.

Purpose of the Study:

  • To evaluate and compare the efficacy of three dural closure techniques after transoral intradural operations in a canine model.
  • To identify the most effective method for achieving a watertight dural seal and preventing complications.

Main Methods:

  • A canine model was utilized to assess primary suture closure, laser patch weld closure, and fibrin glue patch closure for dural defects.
  • Leakage was assessed intraoperatively and via radiographic evaluation and autopsy post-operation.

Main Results:

  • Primary suture closure was inadequate, with significant CSF leakage observed intraoperatively and post-mortem.
  • Laser patch weld closure showed improvement but still resulted in some intraoperative leakage.
  • Fibrin glue patch closure demonstrated superior performance, providing an immediate and persistent watertight seal, even under increased intraspinal pressure.

Conclusions:

  • Fibrin glue offers a highly effective solution for watertight dural closure in complex intradural defects at the craniocervical junction.
  • This technique shows significant clinical potential for preventing CSF leaks and associated severe complications in transoral surgery patients.
  • Fibrin glue merits further investigation in clinical trials for its application in neurosurgical procedures.
