as long as they avoid straining. Nasal emollients and saline are rec-ommended as needed. The patients were seen one month later. In5% of our series, a small crust was noted and removed. At this time,patients with soft-tissue hypertrophy of the turbinates should feelsubstantially improved. Those in whom complete relief has notbeen achieved can be scheduled for other nasal surgery in the ORsuch as septoplasty. For patients who have undergone RFTA in con-junction with other nasal and sinus procedures, standard FESS / sep-toplasty / rhinoplasty care is given, but is much lessened by thereduced morbidity of RFTA versus resection.
The author has performed 438 RFTA procedures using this technique,
with follow-up from one month to five years, in patients ranging from
18-85. The procedure was well tolerated by all of the patients. A sub-
stantial proportion of patients were managed for nasal obstruction
causing CPAP failures in OSAS. Two hundred and twenty of the cases
were performed in the office / clinic, with only four episodes of bleed-
ing requiring conservative treatment. Notably, all four of these patients
had been on anticoagulant therapy, and were treated in the office /
clinic to avoid the risk of anaesthesia. No cases of atrophic rhinitis,
crusting, synechiae, dryness, persistent crusting, olfactory disturbance,
synechiae, necrosis, or any other complication were noted in RFTA-
treated turbinate tissue in either the isolated or combination RFTA
groups. Substantial decrease in the bulk of the turbinate was observed
in all cases. The only patients who ultimately required OR surgery (sep-
toplasty, FESS, or rhinoplasty), were those who were identified preop-
eratively as having bony and cartilaginous deformity, and had elected
RFTA as a minimally invasive procedure, or as a way to avoid OR risks.
More than half of patients whom the author recommended for OR
surgery were satisfied with the improvement from RFTA, despite indi-
cations for more invasive surgery.
Radiofrequency Turbinate Ablation (RFTA) is a safe and highly effec-
tive technique for symptomatic nasal obstruction refractory to
medical therapy, and attributable to hypertrophy of turbinate soft
tissue. Bipolar RFTA preserves the turbinate mucosa, thus minimis-
ing the risk of complications and physiological disturbances from
turbinate reduction. When used in conjunction with excisional
techniques to reduce obstructive turbinate bone, it facilitates
mucosal preservation for the remainder of the turbinate, thus
improving patient tolerance and outcomes. Thus, RFTA should be
considered an effective and cost effective option in the treatment of
nasal obstruction. n
