Role of Novel RADA16 Hydrogel in Endoscopic Skull Base Surgery

The purpose of this study is to specifically evaluate the effectiveness of PuraGel, a RADA16 polypeptide hydrogel, in expediting post-operative healing and re-mucosalization of the nasoseptal flap harvest site during endoscopic skull base surgery and the impact on patient and sinonasal morbidity.

Dural Medical Adhesive for Watertight Sealing in Dural Repair

This is a prospective, multicenter, single-blind, randomized controlled superiority clinical trial of dural medical adhesive for watertight sealing after primary spinal dural repair to prevent cerebrospinal fluid (CSF) leakage. A total of 141 patients with intraoperative CSF leakage after primary dural repair from 7 medical centers will be enrolled at a 2:1 randomization ratio (94 in adhesive group, 47 in standard treatment control group). Intraoperative watertight sealing success rate is the primary outcome. Postoperative CSF leakage rate at day 10±5 and day 90±7, drainage volume/duration, and adverse events/serious adverse events within 90 days are secondary outcomes to evaluate the safety and effectiveness of the investigational device.

Using Polyglycolic Acid Mesh Prevents Cerebrospinal Fluid Leakage

The papers propose a new method to prevent postoperative cerebrospinal fluid leakage. Doctors use the absorbable polyglycolic acid (PGA) and fibrin glue to repair in surgery, prevent cerebrospinal fluid leakage and reduce the necessity of postoperative lumbar drainage after surgery. This study will analyze the changes in cerebrospinal fluid leakage in patients with pituitary tumors and skull base tumors after surgery, and further understand the effectiveness of Neoveil , as the basis for the development of new treatments.
