Abstract:
Objective To investigate the clinical efficacy of the self-retaining laryngeal microsurgical operation in the treatment of Reinke ’ s edema of vocal cords . Methods There were 24 cases of Reinke ’ s edema who were treated with self-retaining laryngoscope mucosal stripping surgery of vocal cords from January 2004 to December 2009 ( traditional group ) , while another group of 32 cases of Reinke ’ s edema were treated with self-retaining laryngoscopic microsurgery lateral submucosal incision micro-flap operation of vocal cords from January 2010 to December 2015 ( laryngeal microsurgery group ) .The two groups were executed with electronic laryngoscopy and subjective voice evaluation GRBAS ( The Speech and Language Institute of Japanese in 1979, G: Grade, R:Roughness, B:Breathness, A:Asthenia, S:Strain) in pre-operation and post-operation (1 week, 3 weeks, 8 weeks).The wound healing time of vocal cords , hoarseness improved time and voice improvement were retrospectively compared between the two groups . Results The patients in laryngeal microsurgery group had earlier voice hoarse improvement and more rapid mucosal epithelial of vocal cords recovery time in post-operation as compared with the patients in the traditional group [voice improving time, (7.3 ±1.9) d vs. (11.3 ±2.7) d, t=-6.481, P=0.000;mucosal epithelial of vocal cords recovery time , (12.2 ±3.1) d vs.(20.1 ±3.4) d, t=-9.062, P=0.000].The results of pre-operative voice evaluation with GRBAS showed no significant differences between the two groups, but the results of post-operative evaluation of each session (1 week, 3 weeks, 8 weeks) showed that the main data were statistically different.The GRBAS score of laryngeal microsurgery group was lower than that of traditional group in post -operation, especially after 8 weeks (8 weeks after post-operation, G:1.0 ±0.8 vs.1.6 ±0.2, t=-3.584, P=0.000; R:1.0 ±0.9 vs. 1.5 ±0.4, t=-2.536, P=0.014;B:1.0 ±0.6 vs.1.4 ±0.5, t=-2.647, P=0.011).In laryngeal microsurgery group, 24 cases were cured , 5 cases were effective and 3 cases were invalid , contrasting in the traditional group with 11 cases of cured , 7 cases of effective and 6 cases of invalid respectively, with a significant difference (Z=-2.239, P=0.025).No significant difference in effective rate between the two groups [90.6%(29/32) vs.75.0%(18/24),χ2 =1.459, P=0.227]. Conclusion The clinical efficacy of self-retaining laryngoscope microsurgery in the treatment of Reinke ’ s edema of vocal cords is faster and better comparing traditional operation , with a more significant pronunciation quality improvement .
