Objective:
Multilevel surgery for obstructive sleep apnea syndrome (OSA) may improve success. This study's goal is to prospectively evaluate the feasibility and short-term subjective effectiveness of a new tongue-suspension technique.
Methods:
A multicenter nonrandomized open enrollment trial used the Repose device to treat tongue obstruction in 39 snoring and OSA patients. Outcomes include 1- and 2-month subjective reports of general health, snoring, and sleep.
Results:
Twenty-three patients completed 1 month and 19 completed 2 months of follow-up. In OSA patients, activity level, energy/fatigue, and sleepiness improved. Two-month outcomes were less (activity level, energy/fatigue, and sleepiness). Fewer changes were observed in snorers than in OSA patients. There were 6 complications (18%), including sialadenitis (4), gastrointestinal bleeding (1), and dehydration (1) after the procedure.
Conclusion:
A pharyngeal suspension suture changes subjective outcomes. Improvement is incomplete. The procedure is nonexcisional, but significant complications may occur. Further evaluation is required to demonstrate effectiveness.
