Sinusplasty is the balloon procedure for the treatment of sinuses, explains American Rhinologic Society. The procedure is an adaptation of cardiac angioplasty, which involves the use of catheters and balloons to open up diseased or blocked blood vessels around the heart.
Sinusitis is a condition in which the mucous membranes of the nose, sinuses and throat become inflamed. This obstructs the sinus openings and prevents normal drainage of mucous, causing buildup and pressure, according to Balloon Sinusplasty.
Sinusplasty treats recurring acute or chronic sinusitis by the insertion of a guidewire through the nose and into the affected sinus. An attached balloon catheter is inflated inside the sinus, widening the outflow tract of the sinus by fracturing bone and pushing back the mucous membrane, notes the American Rhinologic Society.
