Surgical outcome
Table 3 showed post-operative AHI, nighttime SpO2 (CT90 and L-SpO2) and ESS decreased, among 34 OSA patients after UPPP surgery. What’s more, both RSI and RFS decreased after treatment for OSA.
The surgical success rate was 73.53% (25/34). In 25 successful-surgery patients, RSI and RFS were downward after surgery, and the prevalence of LPR changed just after successful UPPP surgery (Table 4 ).
Figure 3showed except for hoarseness (P=0.054), all individual variables of postoperative RSI significantly improved (P <0.05). When we compared the pre- and post-surgery changes in individual variables of RSI to patients in successful or unsuccessful surgeries group, all variables of successful-postoperative RSI improved (P <0.05) except hoarseness and postnasal drip (P =0.117 and P =0.052, respectively), but all variables in the RSI showed no significantly changes after unsuccessful surgery.
