Usefulness of uvulopalatopharyngoplasty with genioglossus and hyoid advancement in the treatment of obstructive sleep apnea

OBJECTIVE: To evaluate the usefulness of uvulopalatopharyngoplasty plus mandibular osteotomy with genioglossus and hyoid advancement in the treatment of obstructive sleep apnea syndrome (OSAS). DESIGN: Prospective study of 20 consecutive patients with OSAS. SETTING: University medical center. PATIENTS AND INTERVENTIONS: Twenty OSAS patients with multilevel upper airway obstruction who refused continuous positive airway pressure treatment. All patients were evaluated before and 6 months after surgery by clinical history, the Epworth Sleepiness Scale, physical examination, fiberoptic nasopharyngoscopy combined with the Müller maneuver, cephalometric analysis, nocturnal polysomnography, and a second-night polysomnography with upper airway pressure recording during sleep. Surgery procedures were uvulopalatopharyngoplasty plus mandibular osteotomy with genioglossus and hyoid advancement. Surgical successful outcome was defined as an apnea-hypopnea index (AHI) lower than 20 plus subjective resolution of daytime symptoms. MAIN OUTCOME MEASURE: Surgical success rate. RESULTS: Mean +/- SD AHI decreased from 60.5 +/- 16.5 to 44.6 +/- 27(P =.007), and CT90 (percentage of time with oxyhemoglobin saturation below 90%) decreased from 39.5% +/- 26% to 25.1% +/- 26.4% (P =.002). The overall surgical success rate was 35% but increased to 57% in patients with moderate OSAS (AHI, 41-60) and to 100% in mild OSAS (AHI, 21-40). In the group of severe OSAS, the success rate was 9%. Predictors of surgical outcome success were the AHI, CT90, stages 2 and 3-4 sleep percentages, and the cephalometric ANB angle (angle formed from the deepest point on the maxillary outer contour to the nasion to the deepest point on the outer mandibular contour). CONCLUSION: Patients with mild and moderate OSAS and multilevel obstruction in the upper airway may benefit from uvulopalatopharyngoplasty plus genioglossus and hyoid advancement.     

Reorganization of sleep architecture after surgery for OSAHS

Conclusion. Genioglossus advancement and hyoid suspension (GAHM) plus uvulopalatopharyngoplasty (UPPP) can decrease the apnea hypopnea index (AHI) and arousal index, especially respiratory-related arousals. Correspondingly, sleep architecture is reorganized, which is expressed postoperatively as an increase in slow wave sleep and a decrease in lighter sleep. Objective. To explore the reorganization of sleep patterns after GAHM plus UPPP for severe obstructive sleep apnea hypopnea syndrome (OSAHS). Patients and methods. GAHM plus UPPP was performed on 31 patients with severe OSAHS (AHI>40). The postoperative follow-up was 6 months. Results. The AHI was reduced from 65.93±23.83 preoperatively to 28.58±29.11 postoperatively. The arousal index was reduced from 56.00±18.78 to 41.97±20.73, and the respiratory arousal index was reduced from 35.44±21.57 to 22.63±21.99. No significant change was seen in the spontaneous arousal index (preoperative, 20.56±12.97; postoperative, 19.34±10.29). The percentage of REM sleep during the total sleep time (TST) increased from 10.53±9.13% to 13.92±6.76%, and the S3+S4 percentage of TST increased from 3.07±3.01% to 7.09±6.83%. Correspondingly, the S1+S2 percentage of TST decreased from 86.53±9.28% to 78.89±8.89%.

Abstract：

Objective To discuss the methodology and therapeutic effect of hyoid suspension in association with uvulopalatopharyngoplasty ( UPPP) in the treatment of severe obstructive sleep apnea hypopnea syndrome (OSAHS).Methods Sixty-nine patients with severe OSAHS( apnea hyponea index,AHI ＞ 30) were treated with hyoid suspension and UPPP.Sixty-one patients were followed for 6 months (48 of them for 12 months).Polysomnogram (PSG) tests were performed and an Epworth sleepiness scale ( ESS) was recorded preoperatively and postoperatively in these patients.Results After the surgery,the snoring of the patients disappeared or was alleviated to varing degrees.Eighteen patients underwent fiberoptic nasopharyngolaryngoscopic examination.Twelve of them showed palatopharyngeal and glossopharyngeal stenosis was improved 6 months after surgery.Six patients showed no change,but had no glossoptosis.Fourteen patients underwent fiberoptic nasopharyngolaryngoscopic examination 1 year after surgery,with no recurrence of the stenosis being found.A decrease of 50% in the AHI was considered effective,and in patients the effective rate was 78.7% (48/61 ) 6 months after the operation and 75.0% (36/48) 1 year after the operation.The average AHI decreased from 44.8 to 15.1 and 17.2,and the minimum arterial oxygen saturation average increased from 0.512 to 0.880 and 0.730.Matching t tests were utilized and the results of follow-up indicated that there was a significant improvement in the indexes in those cases which could be followed up ( P ＜ 0.01 ).The average of the ESS was 6.7 six months after operation and 7.2 one year after operation,with a significant decrease compared to the preoperative ( 16.6) data (P ＜0.01).Conclusions Modified hyoid suspension in association with UPPP has the advantage of a simple operation,short hospitalization and less expense,and the effect of the operation was significant.Patients with palatopharyngeal and glossopharyngeal stenosis should be chosen for this operation.
