Suspension with repose system in the treatment of obstructive sleep apnea-hypopnea syndrome / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To introduce the treatment of severe obstructive sleep apnea-hypopnea syndrome (OSAHS) with Repose bone screw system and to evaluate the treating effect.</p><p><b>METHODS</b>Thirty-two patients with severe OSAHS (Friedman classification II, III) were treated with tongue ablation + uvulopalatopharyngoplasty + hard palate shortening + Repose suspension. All patients were followed-up for 6 months. Apnea hypopnea index (AHI), lowest oxygen percent saturation (LSaO₂), body mass index (BMI), vallecula epiglottic-lateral pharyngeal wall (V-LPW) and pharyngeal airway space (PAS) were used for the diagnosis and evaluation.</p><p><b>RESULTS</b>The AHI in 32 patients reduced from (78.3 +/- 11.6)/h to (18.4 +/- 12.5)/h (x(-) +/- s), t = 13.5, P = 0.000. The LSaO₂ increased from (0.632 +/- 0.007) to (0.794 +/- 0.006), t = 4.1, P = 0.000. The BMI was statistical indiscriminate. The V-LPW increased from (12.1 +/- 3.2) mm to (16.9 +/- 2.6) mm (t = 2.5, P = 0.014). PAS increased from (9.2 +/- 3.3) mm to (15.6 +/- 2.4) mm (t = 7.6, P = 0.000). The total effective rate was 93.8%. Three genioglossus stabilization patients complained about foreign body sensation in the mouth floor 3 - 7 days after procedures, which disappeared in 6 months. One genioglossus stabilization patients complained about mandibular osteomyelitis 3 months after procedures, which recovered after anti-inflammatory treatment for 5 days. One genioglossus stabilization patients appeared hypoglossia bleeding, which stopped after compression. One hyoid suspension patients showed haematoma of submandibular region and cured after incision and drainage.</p><p><b>CONCLUSION</b>Repose system was an effective method, safe, simple, with few complications.</p>
