Objective:

To explore the clinical characteristics, optimal surgical approaches, and prognostic factors of traumatic external auditory canal stenosis (EACS) specifically in children.

Key Findings:
  • EACS in children was characterized by unilateral involvement (100%) and primarily associated with prior ear surgeries (86%).
  • The postoperative recurrence rate was 57% in children, all cases accompanied by restenosis.
  • In adults, the recurrence rate was 25%, with no cases of postoperative restenosis.
  • Statistical analysis showed a significantly higher restenosis rate in pediatric patients compared to adults (P = 0.012).
Interpretation:

The study indicates significant differences in the clinical characteristics and surgical outcomes of EACS between children and adults, suggesting that these findings should inform clinical practice.

Limitations:
  • Small sample size (19 patients total, with only 7 pediatric cases).
  • Retrospective design may limit the generalizability of findings and introduce biases.
  • Lack of multicenter data to validate results.
Conclusion:

There are notable disparities in EACS characteristics between children and adults, emphasizing the need for tailored surgical approaches and long-term follow-up in pediatric cases.
