title: Changes of nasal function after temperature-controlled radiofrequency tissue volume reduction for the turbinate.
abstract: OBJECTIVE
  Temperature-controlled and temperature-monitored radiofrequency tissue volume reduction (RFTVR) for the turbinate is a new treatment modality for nasal obstruction secondary to turbinate hypertrophy. We compared the nasal functions after the treatment ofRFTVR and laser vaporizing turbinoplasty (LVT) using subjective symptom scores and objective tests.
  
  
  METHODS
  Prospective, randomized clinical trial.
  
  
  METHODS
  Twenty-four patients with nasal obstruction secondary to inferior turbinate hypertrophy were prospectively evaluated from March 1999 to October 1999 at Seoul National University Hospital (Seoul, Korea). Sixteen patients were treated with RFTVR, and eight patients with LVT. The preoperative and postoperative nasal functions were investigated by visual analogue scale of symptoms, butanol threshold test, saccharine test, acoustic rhinometry, rhinomanometry, and ciliary beat frequency.
  
  
  RESULTS
  At 8 weeks postoperatively, the severity and the frequency of nasal obstruction improved subjectively in 81.3% and 93.8% of RFTVR group and in 87.5% and 87.5% of LVT group, respectively. Significant improvement of nasal symptoms began from 2 to 3 days after the operation in the RFTVR group, whereas there was significant improvement of nasal symptoms at 8 weeks after operation in the LVT group. However, objective nasal functions including nasal volume and total nasal resistance were significantly improved at 8 weeks after surgery in both groups. Among patients reporting symptoms of hyposmia, 55.6% of RFTVR group and 63.6% of LVT group showed improved olfaction. Saccharin transit time and ciliary beat frequency were preserved after RFTVR CONCLUSION: RFTVR for the turbinate may be useful as an alternative approach for the treatment of chronic turbinate hypertrophy.
