[Uvuplopalatal flap in OSAHS patients with anteriorand posterior pharyngeal plane stenosis].

Objective: Observation of the effect of uvuplopalatal flap for OSAHS patients with anterior and posterior pharyngeal stenosis. Method: Fifty-six patients with OSAHS who were mainly anterior posterior stenosis in the velopharyngeal plane were selected. Patients with suspending uvuplopalatal flap were used as observation group (30 cases). Patients with UPPP were used as control group (26 cases). The investigation and comparison of AHI, SaO₂, scars, throat foreign body sensation, pharynx desiccation, pharynx' s tightness, pharynx discomfort and surgical satisfaction were investigated at 6-8 months after the operation. Restul: At 6-8 months after operation, the AHI and SaO₂ of the two groups were significantly improved compared with those before operation(P<0.01). However, there were significant differences(P<0.01) among the indexes of scar formation, throat foreign body, sensation pharynx desiccation, pharynx' s tightness, pharynx discomfort and surgical satisfaction.
Conclusion: In the OSAHS patients with anterior and posterior pharyngeal stenosis, the effect of UPF was better than that of UPPP among the indexes of scar formation, pharyngeal symptoms and surgical satisfaction.
