Abstract
Maxillary sinusitis is treated by placing a self-supporting temporary drain hose in a wall separating the sinus and a nasal cavity. The hose allows drainage from the sinus, and repeated rinsings without the need of further operations. Between rinsings, air enters the sinus through the hose and kills bacteria therein.
Claims9
A method of treating maxillary sinusitis on a patient with a maxillary sinus comprising the steps of:
- making an opening in a wall of said maxillary sinus;
- placing a self-supporting hose within said opening for communicating with said sinus the hose having means at the distal end thereof to retain said hose within the sinus cavity;
- performing the steps of draining the sinus and rinsing the sinus through the hose at desired intervals.
A method of treating maxillary sinusitis of a patient comprising the steps of:
- providing a drain hose assembly with a drain hose having a distal end, and several projections attached to said distal end, said projections being flexibly movable between a first position in which the projections extend radially away from said hose and a second position in which the projections are substantially in parallel with a hose axis;
- and a hose sleeve telescopically mounted on said hose, said sleeve being axially movable on said hose for moving said projections between said first and second positions;
- making an opening in a wall between a maxillary sinus and a nasal opening;
- inserting the distal end of said drain hose assembly through said opening into said sinus with said hose sleeve positioned to keep said projection in said second position;
- and
- moving said sleeve axially to shift said projections to said first position for retaining the hose in the sinus.
