Endoscopy is indicated for the investigation of persistent or recurrent nasal discharge that does not respond to simple treatment. This procedure allows close inspection of the lesion, and facilitates other methods such as histology, microbiology, cytology, and measurement of ostial patency and mucociliary transport. The importance of direct observation of the morphology and natural colour of normal structures becomes ever more evident. Its regular use has greatly enriched our knowledge of anatomy, physiology and pathology of the nasal cavity and paranasal sinuses. Surgery with endoscopic guidance improves surgical precision, reveals deep seated lesions by a minimally invasive approach, and allows lesion shown by radiography to be examined. The treatment of nasal polyposis is still debated, but previous studies agree that, when surgery is necessary, it must be accompanied by appropriate local and general medical therapy administered pre- and/or postoperatively. Paranasal sinus surgery can cause wounds in areas in which bone is not covered by mucosa and tends to granulate. The location and size of these areas vary, and depend on preoperative anatomy and the type and extent of surgery. The speed of individual recovery depends on local and systemic factors. Local inflammation slows down tissue repair and destroys wide areas of mucosa, which heal with anomalous scar formations leading to a deficit of muco-ciliary clearance that predisposes patients to local relapse. In an attempt to reduce these complications, we have developed a new ethmoidal stent (ET-WASH) which is applied at the end of surgery. The aim of this study was to verify the tolerability of the device, and its advantages in terms of allowing targeted local corticosteroid therapy, reducing synechiae, preserving ventilation, cleansing of the surgical cavity, and reducing the recurrence of polyps.
