Autologous platelet-rich fibrin: a novel method for tracheoesophageal puncture site closure: a case report.

Closure of a tracheoesophageal puncture site performed during voice prosthesis implantation may sometimes be required. Besides local techniques, more elaborate procedures, such as closure by means of free microvascular flaps, have been advocated. In this report, we describe a case of local treatment of a hard-to-heal fistula with local application of autologous platelet-rich fibrin matrix in a 77-year-old male patient. At one-week follow-up, the size of the fistula had decreased dramatically but some leakage remained when drinking. After one month, the patient was able to drink and eat normally without any leakage. There was no recurrence of the leakage at two years' follow-up. In summary, local application of platelet-rich fibrin seems to be a simple, safe and effective procedure for tracheoesophageal fistula closure.
