Abstract

Twenty-two Caucasians (16 male and 6 female) with chronic bilateral nasal obstruction due to hypertrophic inferior turbinates were followed up over a three-month period. They were assessed by clinical examination, as active anterior rhinometry, and acoustic rhinometry before and after topical decongestion, preoperatively and three months after surgery. All patients were treated by application of radiofrequency-volumetric-tissue reduction (RFVTR, or somnoplasty) to both inferior turbinates. Initial postoperative edematous response disappeared during the first week after RFVTR. Three months postoperatively 20 of 22 patients (91%) reported subjective improvement of nasal patency. The average cross-sectional area for both sides of the nasal cavity (measured at the head of the inferior turbinate (C-Notch) before decongestion) increased in 15 of 22 patients (68.2%). This means a significant improvement from 1.24 to 1.49 cm2 for both sides of the nasal cavity (p = 0.0054). We conclude that RFVTR can safely reduce turbinate volume in a precise manner in patients with nasal obstruction due to hypertrophic inferior turbinates.

Main findings

Three months after radiofrequency volumetric tissue reduction of both inferior turbinates, 20/22 patients (91%) reported subjective improvement in nasal patency. Average cross-sectional area (both sides, C-Notch before decongestion) increased in 15/22 patients (68.2%), with a significant mean increase from 1.24 to 1.49 cm2 (p=0.0054). Postoperative edema resolved within the first week.
