| Nasal polyps may cause Nasal Obstruction
 Figure 14. Nasal polyps may cause nasal obstruction. This endoscopic photograph demonstrates nasal polyps emanating from the middle meatus into the nasal cavity.
The use of powered instrumentation has become wide-spread in functional nasal surgery, particularly in endoscopic sinus surgery. Microdebrider-assisted turbinate reduction excises erectile soft tissue of the inferior turbinate under endoscopic visualization while pre-serving the overlying mucosa.
In this approach, make a stab incision at the anterolateral surface of the inferior turbinate. Perform a supraperiosteal elevation of soft tissue over the turbinate bone. A suction elevator is helpful in clearing blood from the surgical plane. Carry the dissection posteriorly and also superolaterally along the lateral nasal wall.
Use a pediatric noncutting microdebrider blade to minimize the risk of perforating the overlying mucosa. Position the active face of the microdebrider outward, toward the mucosal surface. Then perform soft-tissue resection under endoscopic visualization. Outfracture, or resection of a portion of the inferior turbinate bone, may be easily accomplished at the same time, when indicated.
