Area of Science:

  • Otolaryngology
  • Pediatric Surgery
  • Regenerative Medicine

Background:

  • Myringoplasty is a common otolaryngologic procedure for tympanic membrane (TM) perforations in children.
  • Various autografts like fascia and cartilage are used, with fat grafts showing high success rates (80-90%).
  • Traditionally, fat grafts are harvested from the ear or post-auricular region.

Purpose of the Study:

  • To describe the techniques and outcomes of using umbilical fat for pediatric myringoplasty.
  • To evaluate the efficacy of umbilical fat as a graft material in myringoplasty.

Main Methods:

  • Retrospective review of 28 pediatric cases undergoing umbilical fat-graft myringoplasty (June 2008 - January 2011).
  • Assessment of successful tympanic membrane closure rates.

  • Literature review comparing umbilical fat graft outcomes with auricular fat grafts.

    • Main Results:

    • Achieved a 100% rate of successful tympanic membrane closure.
    • Average follow-up duration was 8 months (range: 3-26 months).
    • Umbilical fat demonstrated potential advantages for myringoplasty, supported by literature review.

    Conclusions:

    • Umbilical fat patch myringoplasty is a safe and highly successful procedure for pediatric tympanic membrane repair.
    • This technique offers a promising alternative graft source for myringoplasty.
