BACKGROUND: Selective upper airway stimulation of the hypoglossal nerve is a novel therapy option for @entity27 . @entity5773 were observed after surgery during active therapy. METHODS: We examined tongue motions in 14 @entity1 (mean age 51      10  years) who received an implantation of an upper airway stimulation system (Inspire Medical Systems) from September 2013 to February 2014 in three different implantation centers in Germany after surgery. Sleep recording was performed preoperatively: 2  months (M02) and 6  months (M06) after surgery. RESULTS: There were three different tongue motions observed after surgery at 1  month (M01), M02, and M06 after surgery: bilateral protrusion (BP), @entity2632 ( @entity2632 ), and mixed activation (MA). At M01: 10 BP, 2 @entity2632 , and 2 MA; at M02: 12 BP, 0 @entity2632 , and 2 MA; and at M06: 12 BP, 0 @entity2632 , and 2 MA could be detected. The average @entity27 index (AHI) was reduced from 32.5      14.2/h before surgery to 17.9      23.3/h at M02 and 14.1      19.8/h at M06. An increased reduction in AHI was found in BP and @entity2632 group (Baseline: 29.6      12.6/h; M02: 12.06      14.1/h; M06: 9.7      12.6/h) compared to the MA group (Baseline 49.6      13.8/h; M02: 49.7      5.1/h; M06: 40.5      4.1/h). CONCLUSIONS: These findings suggest that the @entity86 in upper airway stimulation are associated with the therapy outcome. The stimulation electrode placement on the hypoglossal nerve for selective muscle recruitment may play a role in the mechanism of action.
