ENT · Larynx and airway: polytef granuloma

Sample item

Three years after vocal fold injection for paralysis, a patient has worsening hoarseness and a firm mass at the injection site that is not malignant on biopsy. Which material was most likely injected?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Polytef (Teflon)

Polytef injection provokes a foreign-body granulomatous reaction years later, giving a mass and worsening voice. It has been replaced by materials such as fat, hyaluronic acid and calcium hydroxylapatite.

Option by option

  • A. Autologous fat

    Autologous fat is non-reactive though it may partly resorb.

  • B. Absorbable gelatin sponge

    Gelatin sponge is absorbed within weeks to months.

  • C. Hyaluronic acid gel

    Hyaluronic acid is resorbed and rarely causes a late mass.

  • D. Polytef (Teflon) (correct)

    Correct. Late foreign-body granuloma is the known complication of Teflon injection.
