Abstract: PURPOSE: To explore the remolding of upper airway in patients with obstructive sleep apnea-hyponea syndrome (OSAHS) after uvulopalatopharyngoplasty (UPPP). METHODS: Twenty-one male adult patients aged 27 to 52 years were included and followed up from pre-operation to 6 months after operation. Lateral cephalometric radiographs (conventional and when pronouncing "i" ) were taken before operation and 3 days, 1, 2, 3, 6 months after operation. The anterolateral diameters of different level of upper airway and parameters of hyoid position at each time point were measured by AUTOCAD 2015. SAS 8.02 software package was used to analyze the difference. RESULTS: UPPP mainly affected the velopharyngeal and glossopharyngeal areas: parameters wane (P<0.05). On the other hand, UPPP led to the decline and retrusion of hyoid. The nasopharynx kept statical (P>0.05) while the velopharyngeal parameters were increased (P<0.05) with reducing velocities (P<0.05). The glossopharyngeal parameters increased in the first month after UPPP (P<0.05), while hypopharyngeal parameters underwent decline since 2 months after UPPP (P<0.05). The hyoid underwent decline and retrusion (P<0.05) , while endured a short-time increase in the first month after UPPP (P<0.05). CONCLUSIONS: Short-time upper airway remolding after UPPP does exist.
