Technique
Telescopes with diameters of 4mm (adult use) and 2.7mm (pediatric use) and with a variety of viewing angles (0 degrees to 30, 45, 70, 90, and 120 degrees) provide good illumination of the inside of the nasal cavity and sinuses. High definition cameras, monitors and a host of tiny articulating instruments aid in identifying and restoring the proper drainage and ventilation relationships between the nose and sinus cavities. Cultures (putting abnormal sinus secretions into an incubator to check for bacteria and fungi) and biopsies (examining small bits of tissue under a microscope) can be easily obtained to yield valuable diagnostic information to guide postoperative therapy for optimal long term results.
All the sinuses can be accessed at least to some degree by means of this surgery: The frontal sinuses located in the forehead, the maxillary sinuses in the cheeks, the ethmoid sinuses between the eyes, and the sphenoid sinuses located in the back of the nasal cavity at the base of the skull.

Famous quotes containing the word technique:
“Irony in writing is a technique for increasing reader self- approval.”
—Jessamyn West (1907–1984)
“The audience is the most revered member of the theater. Without an audience there is no theater. Every technique learned by the actor, every curtain, every flat on the stage, every careful analysis by the director, every coordinated scene, is for the enjoyment of the audience. They are our guests, our evaluators, and the last spoke in the wheel which can then begin to roll. They make the performance meaningful.”
—Viola Spolin (b. 1911)
“In love as in art, good technique helps.”
—Mason Cooley (b. 1927)
