Abstract EN
This study compared the use of lyophilized glutaraldehyde-preserved bovine pericardium (LGPBP), polytetrafluoroethylene (PTFE), polyethylene terephthalate (PET), and Teflon felt (TF) as implants for vocal cords (VC) medialization and aimed to assess the endoscopic, macroscopic, and microscopic VC changes after medialization in a canine model.
In 18 mongrel dogs, the right VC were medialized with LGPBP and the left were implanted as follows: Group I (n=6): LGPBP and PTFE; Group II (n=6): LGPBP and PET; Group III (n=6): LGPBP and TF.
Surgical handling of the implants was compared.
Three months after surgery, macroscopic and microscopic changes of VC and implants were evaluated.
LGPBP offered the best surgical handling (p=0.005, Kruskal-Wallis).
TF implants showed extrusion (p=0.005, Kruskal-Wallis) and severe inflammation.
All VC formed fibrous capsules around the implants; the ones developed by LGPBP implants were thinner (p=0.001, ANOVA, Tukey).
VC implanted with synthetic materials showed eosinophilic infiltration (p=0.01, Kruskal-Wallis).
We concluded that the LGPBP could be used as an implant for VC medialization because it is biocompatible, easy to handle and remove during surgical procedures, and nonabsorbable or extrudable and produces an inflammatory reaction similar to PTFE and PET.
