Long-term efficacy of submucosal uvulopalatopharyngoplasty for obstructive sleep apnea syndrome.
The objective of the study was the assessment of the long-term efficacy of submucosal uvulopalatopharyngoplasty in patients with obstructive sleep apnea syndrome. Thirty-two of 156 patients who underwent UPPP between January 2001 and March 2007 with a follow-up period of 36-96 months (mean, 56 months) were included in the study conducted at the university affiliated center. Preoperative and postoperative snoring evaluation forms and Epworth Sleepiness Scale (ESC) scores were used for subjective analysis. Preoperative and postoperative respiratory distress index (RDI) levels were evaluated objectively. Patients who had 50% or more reduction in RDI levels postoperatively were named as responders to the procedure. The other patients were named as non-responders. Body mass index (BMI) was also analyzed preoperatively and postoperatively. Snoring disappeared in 83% of the patients, did not change in 13% and deteriorated in 4% of the patients (p < 0.001). Excessive daytime sleepiness decreased in 22 patients (68%) and ESC values decreased from 14.6 ± 3.7 to 6.5 ± 3.9 (p = 0.0001). RDI decreased by more than 50% of the preoperative values in 15 (46.9%) of 32 patients forming the responders and the mean RDI decreased from 33.3 ± 22.9 to 23.7 ± 22.8 (p = 0.027). BMI increased over years (p = 0.0001) evidencing a preponderance in non-responder patients. Submucosal uvulopalatopharyngoplasty is an effective tool in treating patient's subjective symptoms of OSAS. Objective findings suggest that smUPPP is inadequate in treating OSAS. It cannot abolish OSAS, though it can decrease the intensity of the condition in nearly half of the patients. Weight gain decreases the success of the procedure over the years.
