Abstract: The present invention provides minimally invasive devices and methods for accessing the sinuses and their surrounding structures for surgery and other treatments. The anterior ethmoid and maxillary sinuses are accessed and treated under minimal anesthesia with little or no postoperative limitation of activity or adverse symptoms. Direct visual verification of the sinuses and their natural ostia is utilized. Other paranasal sinuses may be treated by this method as well. The sinuses, in particular the maxillary and anterior ethmoid, are accessed via a direct anterior to posterior axis and the natural ostia of those sinuses is directly visualized for placement of a guide-free dilator, in the desired location within the natural ostia. That access to the maxillary ostium is accomplished by the anterior transuncinate “keyhole” approach in which a hole is punched in the uncinate process with the described devices according to the described methods.

Abstract: A method is provided for accessing and treating at least one of a maxillary sinusitis, sphenoid sinusitis and frontal sinusitis. A perforation is created in an uncinate via an anterior keyhole. A position of an MSO is verified using a probe. The probe is used to verify dimensions of the MSO. A verification is made that an anteroposterior length of the ostium is sufficient. A targeted medial displacement of a medial wall of the maxillary sinus and uncinate is made using an uncinate medializing device.
