Objectives:
This study aims to review the spectrum of scarring that may present to an urban, pediatric otolaryngology practice and determine if associations exist between race, scar location, treatment modality, and outcomes following interventions for scarring.
Methods:
Retrospective cohort study among 115 pediatric patients with 138 unique keloids or hypertrophic scars (HTS), and 141 children presenting for tonsillectomy at Tufts Medical Center. Age at presentation and sex assigned at birth were collected for both populations. For those presenting for pathologic scars, income quintile, self-identified race/ethnicity, anatomical location, treatment number and type, and clinical outcome were also analyzed. Multivariate analyses calculated adjusted odds ratios (aORs) and 95% confidence intervals to assess associations between scar subsite, intervention type, and persistence after treatment.
Results:
Compared to individuals presenting for tonsillectomy, a disproportionate percentage of patients presenting for scarring identified as Black (26.6% vs. 13.5%) or Asian (17.4% vs. 7.1%, p = 0.016) or were male (61.7% vs. 49.7%, p = 0.053). Individuals identifying as Black or Asian were more likely to present with ear lobe and neck scars, respectively (50.0% vs. 45.5%, p = <0.001). Ear scars were significantly more likely to receive excision at initial treatment (aOR = 5.86 [1.43-23.96]) compared to other subsites, and were more likely to require >1 treatment (aOR = 5.91 [1.53-22.75]).
Conclusion:
Among pediatric patients presenting with keloids or HTS, children who identified as Black or Asian were more likely to present with ear and neck scars, respectively. Ear scars were frequently treated with excision and appear more likely to require adjuvant treatments and multiple interventions.
