Abstract:
Objective To study the curative effects and characteristics of vocal cord shallow lamina propria resection on the treatment of vocal cord leukoplakia .Methods A total of cases of vocal cord leukoplakia were re-ceived vocal cord mucosa stripping surgery (69 cases) and vocal superficial lamina propria resection with or without suture (69 cases) respectively during January 2006 - December 2011 ,and all cases were taken dynamic laryngosco-py and voice acoustic analysis before surgery ,at 2 weeks ,4 weeks ,6 weeks ,8 weeks ,3 months ,6 months ,and 12 months after surgery .We observed the curative effects and characteristics after operation of two different surgery on the treatment of vocal cord leukoplakia with precancerous lesions .Results Two week after operation ,the vocal cords mucous wave ,vocal cords vibration symmetry ,regularity ,total hoarseness degree (G) ,Jitter ,Shimmer , NHRvaluesinthe2groupsweresignificantlylowerthanthoseofpreoperation(P<0.05),buttherewerenosignif-icant differences between the two groups(P>0 .05) .The three main index of dynamic laryngoscope ,voice acoustic parameters at 4 weeks after operation were significantly lower than those at 2 weeks after operation in the vocal cord mucosa stripping surgery group ,the difference were statistically significant (P<0 .05) ,but it showed no statistical difference between the group at 6 weeks after operation and the groups at other time points (P>0 .05) .The three main index of dynamic laryngoscope ,voice acoustic parameters at 6 weeks after operation were significantly lower than those at 2 ,4 weeks after operation in the vocal cord shallow lamina propria resection group ,the difference were statistically significant (P<0 .05) ,but it showed no statistical difference between the group at 8 weeks after operation and the groups of other time points (P>0 .05) .The voice restoration was faster in the vocal cord mucosa stripping surgery group .The recurrence rate was lower in the vocal cord shallow lamina propria resection group than those in the traditional vocal cord mucosa stripping surgery group ,the difference was statistically significant (P<0 .05) . Conclusion The vocal cord shallow lamina propria resection is a minimally invasive operation for the treatment of vocal cord leukoplakia ,with low recurrence rate and good the voice recovery .
