Clinical Features and Complications of External Auditory Canal Foreign Bodies in the ENT Emergency Unit

<b>Objective:</b> To determine the risk factor for developing complications in patients undergoing removal procedures for foreign bodies (FBs) in the external auditory canal (EAC) in the otolaryngology (ENT) emergency unit. <b>Methods:</b> Cases involving patients with EAC FBs treated at the ENT emergency unit of a tertiary medical center were retrospectively recruited. Patients were classified into the age < 10 years and ≥10 years groups. Univariate analyses of the complication rates were performed in all patients and the two age groups. <b>Results:</b> The mean age of the 457 patients was 29.9 ± 19.9 (range, 1.0-89.0) years; 42.7% (n = 195) were under 10 years of age, and 57.1% (n = 261) were male. Complications following FB removal occurred in 40 cases (8.8%), with EAC laceration being the most common (4.4%). Patients under 10 years of age had a higher risk of developing complications than those over 10 years (13.8% vs 5.0%, <i>P</i> = .001), with the younger group also showing an increased risk of EAC laceration (6.7% vs 2.7%, <i>P</i> = .039). <b>Conclusion:</b> Patients under 10 years of age had a significantly-higher rate of complications after EAC FB removal in the ENT emergency unit. Sedation or surgical removal under general anesthesia should be considered to minimize the risk of complications after a failed removal under direct vision in this patient group. Further studies are warranted to verify this implication for clinical practice.
