Balloon catheter technology appears safe and effective in relieving ostial obstruction. Patients were pleased and indicated that they experienced symptomatic improvement.
Patients who receive balloon catheter sinusotomy in endoscopic sinus surgery have significant improvement in symptoms two years after surgery. Radiographic evidence also confirms resolution of disease after two years. This demonstrates durability of clinical results previously reported at 24 weeks and one year after surgery.
This initial study suggests that catheter technology can be used to dilate sinus ostia safely. Mucosal preservation and ease of use make catheters an attractive minimally invasive treatment strategy. Additional testing in patients is indicated to gain additional safety information and to explore the usefulness of catheter-based technology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
