[Total voice prosthesis incarceration in the trachaeo-oesophageal mucosa. Report of a new complication when using phonatory prostheses].
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.
