This study shows that basic fibroblast growth factor (bFGF) with a special membrane patch effectively closes tympanic membrane perforations. This new method significantly improves hearing and offers a successful conservative treatment option.

Area of Science:

  • Otolaryngology
  • Regenerative Medicine
  • Biomaterials Science

Background:

  • Tympanic membrane perforations are common ear conditions that can impair hearing.
  • Current treatments for tympanic membrane perforations have varying success rates.
  • Novel therapeutic approaches are needed for effective tympanic membrane closure.

Purpose of the Study:

  • To evaluate the efficacy of basic fibroblast growth factor (bFGF) combined with an atelocollagen/silicone bilayer membrane for tympanic membrane perforation closure.
  • To assess the impact of this novel treatment on hearing improvement and perforation healing time.

Main Methods:

  • A prospective study involving patients with tympanic membrane perforations.
  • Application of an atelocollagen/silicone bilayer membrane infiltrated with bFGF (Trafermin) or saline (control) to the perforation margins.

Related Experiment Videos

  • Monitoring of perforation closure rates, healing duration, and audiometric outcomes.

    • Main Results:

    • Complete tympanic membrane perforation closure was achieved in all patients treated with bFGF (9 patients).
    • In contrast, only 2 out of 5 patients in the control group achieved perforation closure.
    • bFGF treatment resulted in complete closure within an average of 3.7 weeks and a hearing improvement of 13.3 dB.

    Conclusions:

    • Basic fibroblast growth factor (bFGF) combined with an atelocollagen/silicone bilayer membrane is a highly effective treatment for tympanic membrane perforations.
    • This approach offers a promising conservative method for tympanic membrane repair with significant hearing recovery.
    • The study supports the use of bFGF as a growth factor to enhance tissue regeneration in otologic surgery.
