Analyze the Role of Endoscopic Operation in the Cerebrospinal Fluid Rhinorrhea Repair

OBJECTIVE:To explore the effect of the different operative methods on the results with endoscopy in the cerebrospinal fluid rhinorrhea according to different location and different size.METHOD:All clinical records and data were studied retrospectively, compare repair measure under different size and different location of fistula.RESULT:(1) Size of fistulas: 1 mm x 1 mm - 20 mm x 20 mm; (2) Repair methods: 2 cases were repaired by "Bath-plug" method, 10 by onlay, 18 by underlay, and 1 by "Button with fascia".CONCLUSION:(1) The suitable repair methods were selected according to size and location. Underlay is superior to resist intracranial pressure and better for middle size fistula. Onlay is simple and fit to small fistula. "Bath-plug" method was more reliable for the small-middle size fistula. "Button with fascia" was more suitable to large size fistula. (2) Advantages of the endoscopic technique include exact identification of the site of the dural tear, excellent field of vision, less complication and precise placement of graft.
