ABSTRACT
Objective To compare the histological fates and the effects of autologous fat and fascia used as augmentative materials to treat unilateral vocal fold paralysis (UVFP). Methods Vocal fold augmentation with autologous fat and fascia was performed on 2 dogs (group A) to cure glottic insufficiency caused by left vocal fold paralysis. Autologous fat and fascia 0.4 ml were injected respectively into left and right vocal folds of 9 dogs (group B). The dogs of group B were killed after 1,3 and 5 months and the dogs of group A were killed after 8 months. The histology of both substances and the effect of treatment were evaluated. Results Surviving autologous fat grafts was found in the canine vocal fold after 8 months, but the absorption was too rapid to maintain the bulk of grafts, the effect could last no more than 5 months. Autologous fascia also survived after 8 months, Conclusion The results showed that these two augmentative materials were both effective in the treatment of IJVFP. Autologous fat can only be used as short - term augmentative material. However, autologous fascia has a potential use for long - term application to correct glottic insufficiency caused by UVFP and other diseases.
