Curative effect of surgical treatment of vocal cord polyp under self-retaining fibrolaryngoscope and fibrolaryngoscope

摘要

Objective:To evaluate the curative effect of surgical treatment of vocal cord polyp under self-retaining fibrolaryngoscope and fibrolaryngoscope.Methods: A total of 118 patients with vocal cord polyp who received surgical treatment in our hospital between August 2013 and August 2015 were included in the study, the treatment process was retrospectively analyzed, and according to different operation methods, patients were divided into observation group (n=61) who received surgical treatment under self-retaining fibrolaryngoscope and control group (n=57) who received surgical treatment under fibrolaryngoscope. Differences in voice electroglottography parameters, oxidative stress system indexes, trauma-related indexes and so on were compared between two groups of patients 2 weeks after operation.Results:Jitter, Shimmer and NNE levels of observation group were significantly lower than those of control group while HNR and SNR levels were significantly higher than those of control group;SOD T, SOD Cu-Zn and T-AOC content in serum of observation group were significantly higher than those of control group while H2O2 and AOPP content were significantly lower than those of control group;NPY,β-EP, PGI2, HMGB-1 and HSP72 content in serum of observation group were significantly lower than those of control group.Conclusions:Surgery under self-retaining fibrolaryngoscope can better realize the accurate resection of vocal cord polyp, protect the normal vocal cord function and also reduce the body trauma, and it is a more ideal way of surgery.
