Introduction: Ensuring optimal visualization of the surgical field is paramount during endoscopic procedures. However, endonasal endoscopic surgery often encounters challenges such as blurred vision due to blood, smoke from cautery devices, and bone dust. While commercial tools exist to address these issues, they are costly and unavailable in resource-constrained settings. Materials and Method: In our study, we devised a low-cost solution using a modified disposable triple lumen catheter commonly used in urology. This catheter was attached to the rigid nasoendoscope using disposable water-resistant tape. The system was then connected to a suction machine, with a syringe acting as a two-way system—providing continuous suction and serving as an irrigator. This setup allowed for clear vision during endoscopic endonasal procedures. Conclusion: Our easy-to-build system has significantly improved the endoscopic endonasal procedure in terms of both time consumption and maintenance of clear surgical fields. As a result, it has made the entire procedure easier for both the main surgeon and assistants. However, further studies are needed to objectively measure the improvement and compare it with conventional procedures and commercially available endoscopic-assisted surgical devices. © 2024, Egyptian Society of Ear Nose Throat and Allied Sciences.
