The invention is directed to a system and method for a less invasive surgical tool and operation to correct sinus disease called balloon sinuplasty. The reusable sinus dilation instrument has a guide seeker constructed from a sterilizable material with a bended terminal end offset from an attachment terminal end and a central grip intermediate of the terminal ends. The instrument also includes a removable handle capable of being attached to the attachment terminal end at a predetermined orientation relative to the bended terminal end of the guide seeker depending upon if the instrument is a frontal sinus guide seeker, a maxillary sinus guide seeker or a sphenoid sinus guide seeker. The bended terminal end of the guide seeker can be selectively angled so that the guide seeker is a frontal sinus guide seeker, a maxillary sinus guide seeker or a sphenoid sinus guide seeker.
