Polyethylene cannula for frontal sinus drainage after trepanopuncture
In the diagnosis and treatment of frontitis, frontal sinus trepanopuncture is widely used, after which the sinus is flushed and medication solutions are injected into it through a drainage cannula. Drainage cannula must be reliably fixed, have a sufficient lumen for the introduction of medications, not cause pain during manipulation, soft tissue bedsores. Existing metal cannulas with a mandrel for the frontal sinus do not meet all these requirements.
