Polytetrafluoroethylene (PTFE) injection is a reliable technique for vocal cord paralysis, effectively rehabilitating dysphonia and aspiration. Complication rates are low and strongly linked to technique and material, making it a viable option for many patients.

Area of Science:

  • Otolaryngology
  • Speech and Voice Science
  • Biomaterials

Background:

  • Recurrent laryngeal nerve paralysis can cause significant dysphonia and aspiration.
  • Vocal fold medialization techniques are crucial for rehabilitating patients with vocal cord paralysis.
  • Polytetrafluoroethylene (PTFE) injection has been utilized for vocal fold augmentation.

Purpose of the Study:

  • To evaluate the reliability and success of Polytetrafluoroethylene (PTFE) injection for vocal cord paralysis.
  • To assess the incidence of complications associated with PTFE vocal fold injection.
  • To determine the long-term viability and patient acceptance of PTFE injection as a rehabilitation technique.

Main Methods:

  • Retrospective review of patients undergoing vocal fold injections with Polytef paste at Mayo Clinic since 1982.

  • Analysis of complication rates, specifically PTFE removal procedures.
  • Consideration of factors influencing the choice between PTFE injection and alternative medialization methods.

    • Main Results:

    • 360 patients received Polytef injections for vocal fold augmentation.
    • 16 patients required PTFE removal, indicating a low complication incidence.
    • The true incidence of complications is uncertain but considered very low, influenced by technique and PTFE characteristics.

    Conclusions:

    • Polytetrafluoroethylene (PTFE) injection is a reliable and successful technique for rehabilitating dysphonia and aspiration due to vocal cord paralysis.
    • With appropriate patient selection and technique, Polytef injection remains a viable and acceptable option.
    • Patient prognosis, vocal demands, cost, and physician preference are key factors in selecting vocal fold medialization strategies.
