Abstract
Objective:
To study long‐term results in patients undergoing uvulopalatal flap (UPF) for obstructive sleep apnea (OSA).
Design:
Prospective, clinical trial at tertiary referral center.
Material and Methods:
A study was undertaken on 83 OSA patients with palatal obstruction based on radiography and physical findings. UPF was conducted to increase the airway space and data were analyzed.
Results:
Patients had a mean age of 36.5 ± 12.3 years and a mean body mass index (BMI) of 29.4 ± 4.3 kg/m^2^. The mean follow‐up was 54.2 ± 8.9 months, with a range of 48 to 62 months. The mean baseline apnea‐hypopnea index (AHI), short‐term AHI, and long‐term AHI were 45.6 ± 10.3, 13.4 ± 5.2, and 19.4 ± 5.1, respectively. The mean baseline lowest oxygen saturation (LSAT), short‐term LSAT, and long‐term LSAT were 82.6 ± 5.4%, 89.2 ± 4.8%, and 88.1 ± 3.2%, respectively. Forty‐three patients (51.8%) had long‐term success, and 15 patients(25.8%) had an increase in the AHI over the follow‐up period such that they were no longer considered success by traditional AHI criteria. Serious complications were not encountered.
Conclusions:
UPF is a safe and effective procedure that results in long‐term success for OSA. However, a regular follow‐up is important because some patients will relapse in the long term. Laryngoscope, 2011
