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.
