Randomized Clinical Trial of Nasal Turbinate Reduction to Improve Continuous Positive Airway Pressure (CPAP) Outcomes for Sleep Apnea

Radiofrequency Turbinate Reduction

The steps of the procedure are as follows: 1) application of topical anesthetic to the turbinate mucosa bilaterally; 2) injection of 1.0 ml of lidocaine 1% with epinephrine 1:100,000 with a 30-gauge needle into each inferior turbinate anteriorly; 3) delay five minutes for local anesthetic to take full effect; 4) re-insertion of the anesthetic needle to check for complete anesthesia on one side, and injection of another 1.0 ml of lidocaine 1% with epinephrine 1:100,000 5) placement of the radiofrequency electrode (23-gauge, 1 cm long) into the inferior turbinate; 6) delivery of 300 Joules of radiofrequency energy to the turbinate over 29 seconds (no energy will be delivered in sham procedure)7) placement of a cotton pledget (soaked in oxymetazoline solution 0.05%) against the treatment site 8) repeat steps 3 - 8 for the contra-lateral inferior turbinate; 9) removal of the cotton pledgets after several minutes; and 11) observation of hemostasis.
