[Subjective outcomes after modified maxillomandibular advancement for the treatment of obstructive sleep apnea syndrome].

OBJECTIVE

To evaluate subjective outcomes after modified maxillomandibular advancement(MMMA) for the treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS).

METHODS

In the study, 15 patients underwent MMMA for the treatment of OSAHS and received presurgical and postsurgical polysomnography. A questionnaire was done pre- and postoperatively. The questionnaire included the Epworth sleepiness scale (ESS), snoring, witnessed apneas, CPAP use, and satisfaction of the treatment.

RESULTS

The preoperative polysomnography results of the patients were as follows: apnea-hypopnea index, 40.5±12.8 per hour; lowest oxygen saturation, 73.0%±7.4%; the postoperative polysomnography results were as follows: apnea-hypopnea index, 6.5±3.5 per hour; lowest oxygen saturation, 90.8%±2.1%.Preoperatively, the mean ESS score of the patients was 17.6. Postoperatively, the mean ESS score decreased to 4.3. CPAP was in nine patients before surgery and postoperatively no patients continued. All the patients were satisfied with the treatment and wanted to recommend the treatment to other patients with OSAHS.

CONCLUSION

The review demonstrated that AHI,LSAT,EDS,snoring and witnessed apneas were improved greatly after MMMA technique for the treatment of OSAHS.
