Abstract

BACKGROUND AND OBJECTIVES: The objective of this research was to study the change of lung volume after uvulopalatopharyngoplasty (UPPP) in obstructive sleep apnea (OSA) patients. MATERIALS AND METHOD: Eight OSA patients were participated in this study. These patients were treated with UPPP at Seoul adventist hospital. Vital capacity (VC), inspiratory capacity (IC), expiratory residual volume (ERV) and FEV1, FEV1/FVC, FEV25-75% were determined by standard spirometry at the preoperative, at 3 postoperative days and 1 postoperative month.
RESULTS
Vital capacity (VC) was significantly larger at 3 post-operative days (3.58+/-0.87 L, mean+/-SD) than those at pre-operative (3.12+/-0.69 L, mean+/-SD) in the patient with OSA (p=0.047). FEV 1 (L) was larger at 3 post-operative days (2.91+/-0.76 L, mean+/-vSD) than those at pre-operative (2.68+/-0.85 L, mean+/-vSD), but was not significantly correlated statically (p=0.249).
CONCLUSION
We found significant correlation between preopeative and postoperative VC, IC.
