A new approach in construction of nasal septal obturators.

Nasal septal obturators are used to mechanically close nasal septal defects. The use of an impression of the nasal septal defect in the construction of nasal septal obturators is mandatory. A heat-cured, highly polished acrylic resin button constructed from an accurate impression is less likely to induce crusting and bleeding, or to be dislodged, than a Silastic button.
