OSA treatment outcomes
In group 1, patients presented a mean preoperative AHI value of 40.3±
15.7 which was reduced to a postoperative value of 16.7± 13.4, with a
statistically significant difference (p = 0.0001) (Table
3).
In group 2 the patients presented a mean preoperative AHI value of
37.7±15.8 and a postoperative value of 6±4.1, so that also in this case
a statistically significant difference emerged between preoperative and
postoperative values (p = 0.0001) (Table 3). ODI and LOS
data of the two groups of the study are reported in Table
3. In both groups a statistical difference between preoperative and
postoperative average values of these parameters emerged.
The Delta-AHI (-23.7 ± 14.3 vs -31.7 ± 15.6; p = 0.001), as well as the
Delta-ODI (-24.5 ± 9.5 vs. -29.4 ±10.5; p = 0.001) of the two groups of
patients revealed best values in CPAP group, with a statistically
significant difference compared to the TORS group.
The therapeutic success rate was found to be 73.1% in patients treated
by multilevel surgery and 91% in patients treated with CPAP (p = 0.01)
