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.
