“…This can occur when a vascularized flap receives too much pressure from a fixed balloon. 7 , 12 ) It interferes with the blood supply to the NSF that is usually vascularized by the sphenopalatine artery. We placed the Foley catheter and the Epistat nasal catheter under monitoring by endoscopic inspection, with attention to proper inflation.…”

Cerebrospinal fluid (CSF) leakage is a major complication following endoscopic endonasal skull base surgery. Various skull base reconstruction methods are available, and the use of a vascularized nasoseptal flap (NSF) in skull base reconstruction has greatly contributed to a decrease in the CSF leak rate. A balloon catheter such as a sinus balloon or a Foley catheter is often used to support an NSF; however, in cases wherein nasal and/or paranasal structures supporting the balloon are lacking following the surgery, the NSF is not properly fixed and postoperative CSF leak may occur. Here we introduce a new technique of using multiple-balloon catheters to fix an NSF in such cases and provide the results of our analysis of the new technique's efficacy. Eight patients who underwent endonasal endoscopic surgery for the following cases were included: olfactory neuroblastoma (n = 6), recurrent craniofacial meningioma (n = 1), and recurrent chordoma (n = 1). After tumor resection, multilayered reconstruction with vascularized NSF was performed. Given that the Foley catheter was not stable to fix the flap in each case, we used an additional nasal catheter to support the Foley catheter. No complications such as postoperative CSF leak and necrosis of the vascularized flap were observed. These results suggest that the multiple-balloon catheter technique is a useful method for fixing the NSF to the skull base even when nasal cavity structures are missing due to surgical removal.

“…In single cases, pyramid-shaped balloons known from midfacial traumatology (for stabilization of the orbital floor), Fogarty catheters, or often even simple sponge tamponades are used. The bare cartilage and bone at the septum are covered by silicone sheaths for about 10 days to 4 weeks [ 55 ], [ 122 ], [ 205 ], [ 295 ], [ 383 ], [ 520 ], [ 525 ], [ 594 ], [ 598 ], [ 599 ].…”
