Expansion Sphincter Pharyngoplasty: A New Technique for the Treatment of Obstructive Sleep Apnea
Abstract
OBJECTIVE: In this study, we assessed the efficacy of a new method (expansion sphincter pharyngoplasty [ESP]) to treat obstructive sleep apnea. STUDY DESIGN: We conducted a prospective, randomized controlled trial. METHODS: Forty‐five adults with small tonsils, body mass index less than 30 kg/m 2, of Friedman stage II or III, of type I Fujita, and with lateral pharyngeal wall collapse were selected for the study. RESULTS: The mean body mass index was 28.7 kg/m 2. The apnea‐hypopnea index improved from 44.2 ± 10.2 to 12.0 ± 6.6 (P < 0.005) following ESP and from 38.1 ± 6.46 to 19.6 ± 7.9 in the uvulopalatopharyngoplasty group (P < 0.005). Lowest oxygen saturation improved from 78.4 ± 8.52% to 85.2 ± 5.1% in the ESP group (P = 0.003) and from 75.1 ± 5.9% to 86.6 ± 2.2% in the uvulopalatopharyngoplasty group (P < 0.005). Selecting a threshold of a 50% reduction in apnea‐hypopnea index and apnea‐hypopnea index less than 20, success was 82.6% in ESP compared with 68.1% in uvulopalatopharyngoplasty (P < 0.05). CONCLUSION/SIGNIFICANCE: The ESP may offer benefits in a selected group of OSA patients.

In comparison to the Pang-Woodson technique, the pulling suture works at a 90-degree angle on the muscle fibres array, with much less risk to tear the flap tip.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
