The Suture-Pull as a Refinement of the Gasket Implant Technique for Reconstruction after Endoscopic Skull Base Surgery
ABSTRACT
Introduction: Adequate reconstruction of the skull base is the key to avoiding cerebrospinal fluid (CSF) leak following endonasal skull base surgery. The use of an endocranial “gasket” plug has been reported for this and is used in our institution. We present a simple refinement of the “gasket” technique using commonly available materials that helps ensure proper size and positioning of the gasket by applying stress on a suture attached on the center of the gasket implant. Materials and Methods: We report a case of massive CSF leak following endonasal transsphenoidal surgery for pitui- tary macroadenoma. The skull base was reconstructed in a multi-layered fashion with fascia lata and bony buttress reinforced with a vascularized nasoseptal flap. In order to avoid implant slippage from too-small size or malpositioning, we performed a “stress test” using traction applied to a suture attached to the center of the implant (Medpor®), which allowed us to confirm intraoperatively that the buttress was positioned securely. Results: The patient did well without recurrence of CSF leak. At two-year follow-up, there has been no recurrence of CSF leak or occurrence local complica- tions. We have not verified whether bony regrowth into the implant has occurred. Conclusion: The suture-pull refinement of the gasket implant technique is a simple, inexpensive and low risk method to assure secure endocranial positioning over the skull base defect, and may prevent CSF leak resulting from too-small sizing or buttress malpositioning.
