[Polysomnographic results before and after uvulopalatopharyngoplasty (UPPP)].

Uvulo-palato-pharyngo-plastic is one possibility for treatment of obstructive sleep-apnea. We examined in a prospective study design 36 patients, suffering from polysomnographically ensured obstructive sleep-apnea-syndrome, who were undergone uvulo-palato-pharyngo-plastic. We analysed pre- und postoperative polysomnographic data. Most of patients demonstrated a decrease of amount of apneas, duration of apneas and an increase of minimal oxygen-desaturation. Patients who had high amounts of apneas (AI > 40/h) or who had a Broca-index > 140 p.c. gained not as much from surgical treatment as other patients did.
