Hypertonic saline injections to enhance the radiofrequency thermal ablation effect in the treatment of base of tongue in obstructive sleep apnoea patients: a pilot study

Abstract

Twelve males and one female with a median age of 50 years (range 41-62) entered the study. Six patients (46%) had more postoperative swelling in the upper airway than expected. Three patients were defined as cured. The trend in the questionnaires was clear, but not significant. In the soft tissue airway CR measurements no significant changes were encountered, although a trend towards volume reduction was seen in the posterior airway space measure.

Radiofrequency surgery of the soft palate in the treatment of mild obstructive sleep apnea is not effective as a single‐stage procedure: A randomized single‐blinded placebo‐controlled trial

“…Cephalometric radiographic (CR) analysis was done at a maximum of 3 months preoperatively and a minimum of 4 and maximum of 6 months after treatment with patients in upright and supine body positions 9. The landmarks identified from lateral cephalograms were digitized (twice with 2‐week intervals in order to minimize the intraexaminer variation) and computer registered, and linear and angular variables were calculated (Viewbox 3.1 Cephalometric Software; dHal Software, Kifissia, Greece).…”

The skeletal reference points and lines for measurement of head posture were defined accordingly 9. Cephalograms were analyzed in a single‐blinded manner.…”

Predicting compliance for mandible advancement splint therapy in 96 obstructive sleep apnea patients

“…The landmarks identified from CR images were digitized by two authors (TI and SA), registered on a computer, and then linear and angular variables were calculated (Viewbox † 3.1-Cephalometric Software, dHal Software, Kifissia, Greece). The skeletal, soft tissue, and pharyngeal reference points and lines are presented in Figure 1 (Virkkula et al, 2003;Bäck et al, 2009;Ahrens et al, 2010).…”
