Autogenous fat injections effectively treat paralyzed vocal cords, improving voice quality and lasting over time. This technique offers a viable alternative to traditional methods for vocal cord augmentation.

Area of Science:

  • Otolaryngology
  • Vocal Cord Surgery
  • Regenerative Medicine

Background:

  • Vocal cord paralysis and defects cause significant voice impairment.
  • Current treatments for vocal cord paralysis have limitations.

Purpose of the Study:

  • To evaluate the efficacy of autogenous fat injections for vocal cord augmentation and medialization.
  • To assess the long-term viability and outcomes of implanted fat cells.

Main Methods:

  • Intracordal injection of autogenous fat harvested from the abdominal wall.
  • Treatment of 11 patients with vocal cord paralysis and 1 with a surgical defect.
  • Evaluation using subjective voice analysis and objective videostroboscopy.

Main Results:

  • All patients demonstrated significant voice characteristic improvements.
  • Observed reduction in airflow and increased vocal intensity.
  • Sustained correction of glottic insufficiency, indicating fat cell viability.

Conclusions:

  • Autogenous fat injection is a safe and effective method for vocal cord augmentation.
  • Fat implantation offers a lasting solution with no observed loss of vocal cord substance.
  • Autogenous fat presents a promising alternative to existing treatments like Teflon or collagen.
