1. AIM: To find out the meaning and effect of hypotension general anesthesia (HGA) being used in uvulopalatopharyngoplasty(UPPP)for the patients of obstructive sleeping apnea syndrome ( OSAS ).

2. Objective:To explore the effect of modified uvolopalatopharyngoplasty(UPPP) operation for obstructive sleep apnea hypopnea syndromes(OSAHS)patients.

3. Comparing UPPP with CPAP(continuous positive airway pressure), PSG changes were larger in CPAP.

4. To explore the complications that happened after uvulopalatopharyngoplasty (UPPP) combined with hyoid suspension for obstructive sleep apnea hyperventilate syndrome (OSAHS) patients.

5. A procedure known as uvulopalatopharyngoplasty (UPPP) may help some patients improve or even eliminate their obstructive sleep apnea (OSA), according to a new study.

6. Methods To study 43 cases after UPPP and 43 cases after modified UPPP ( uvula remaining) at complications, symptom improving and oropharyngeal cavity measurement.

6. try its best to collect and create good sentences.

7. Conclusion: Diomed laser for UPPP can enlarge the horizontal air passage of soft palate.

8. According to Dr. Khan, UPPP provided an improvement in oxygen levels and other parameters of sleep, as well.

9. Objective:To investigate the curative effect of the improved uvulopalatopharyngoplasty (UPPP) in different obstructive site of severe obstructive sleep apnea hypopnea syndromes (OSAHS).

10. In addition, researchers say UPPP also can eliminate OSA completely in some patients.

11. AIM To appreciate the meaning of induced hypotension (IH) being used undergoing uvulopalato pharyngoplasty (UPPP).

12. ObjectivesTo explore a more suitable pathway after UPPP in order to reduce the cracking of incision suture.

13. Conclusions:With active clinical treatments, postoperative tracheal intubations are safe and effective in patients with OSAHS, which can avoid severe postoperative complications after UPPP.

14. Objective To investigate the therapeutical effect of uvula - preserving uvulopalatopharyngoplasty ( UPPP ).

15. OBJECTIVE To explore the therapeutic mechanism of treating the obstructive sleep apnea syndrome with hard palate shortening uvulopalatopharyngoplasty(HPS UPPP).

16. Objective To explore the effect of uvula remaining for uvulopalatopharyngoplasty ( UPPP ).
