OBJECTIVE.: DESIGN.: SETTING.: SUBJECTS.: INTERVENTIONS.: METHODS.: OUTCOME MEASURES.: RESULTS.: Group S had a significantly higher proportion of patients who exhibited postoperative pain than group P (24.3% vs 4.5%, respectively; P < 0.05). FPS score in group P was 1.2 ± 0.6, compared with 3.4 ± 1.5 in group S (P < 0.001). Mean recovery time in group S was significantly shorter than the corresponding mean for group P (10.1 ± 1.3 vs 16.5 ± 5.4 minutes, respectively; P < 0.001). CONCLUSION.
