Introduction:
Polydimethylsiloxane (VOX Implant®) injection into the larynx is a surgical technique used to restore volume to paralysed or atrophic vocal folds. We present a case series that demonstrates the feasibility of explantation of this non-resorbable material in the event of complications secondary to this injection.
Description:
We report four cases of VOX Implant® explantation. In every case, explantation was performed following complications such as dysphonia and/or dyspnoea secondary to injection of this material. VOX Implant® explantation was performed via cordotomy using transoral lasermicrosurgical techniques.
Discussion:
VOX Implant® explantation improved voice and breathing parameters in all patients. Explantation can be performed by transoral microsurgery in the presence of complications related to polydimethylsiloxane injection.
