This study introduces a meatoplasty technique using a postauricular island pedicle flap for congenital external auditory canal atresia. The procedure successfully created a lasting canal and improved hearing in most patients.

Area of Science:

  • Otolaryngology
  • Plastic Surgery
  • Regenerative Medicine

Background:

  • Congenital external auditory canal atresia presents challenges in creating a functional auditory canal and improving hearing.
  • Existing surgical techniques may have limitations in terms of canal stability and hearing outcomes.

Observation:

  • A novel meatoplasty technique was employed in three patients with congenital external auditory canal atresia.
  • The procedure utilized a postauricular island pedicle flap, which was fashioned into a tubed and then a blind tube pedicle flap with a free skin graft.

Findings:

  • Two out of three patients experienced significant improvements in hearing acuity following the meatoplasty.
  • All three patients achieved a patent external auditory canal without recurrence of atresia post-surgery.

  • The island pedicle flap, nourished by the posterior auricular artery, provided adequate coverage for the newly created canal.

    • Implications:

    • This one-stage meatoplasty procedure offers a viable solution for congenital external auditory canal atresia.
    • The technique demonstrates potential for durable canal reconstruction and meaningful hearing improvement.
    • Further research may explore the long-term efficacy and broader applicability of this surgical approach.
