Incarceración total de prótesis fonatoria en la mucosa traqueoesofágica. Informe de una nueva complicación con el uso de prótesis fonatorias

We report the cases of three patients seen at the Otolaryngology Department after presenting a laryngeal carcinoma that required total laryngectomy, followed by trachaeo-oesophageal puncture and Provox voice prosthesis positioning. In all cases the growth of granulomatous tissue totally incarcerated the prosthesis in the trachaeo-oesophageal mucosa. In two of the cases the prosthesis could be extracted by oesophagoscopy and a new prosthesis was positioned in the same surgery. In the other case an external approach was performed using a peristomal wound to extract the prosthesis. In this case a new trachaeo-oesophageal puncture was performed 3 months after the extraction.
