Patient Story
A 3-year-old girl is brought by her parents to an urgent care facility after a day of crying, irritability, scant otorrhea, and frequent pulling of her right ear. Otoscopy reveals an erythematous, swollen external auditory canal (EAC) where a bead is wedged (Figure 24-1). The patient is referred to an otolaryngologist and the bead is removed using an operating microscope for visualization.
Introduction
Epidemiology
Etiology and Pathophysiology
-
Most common FBs in children include:5
-
Inanimate objects such as beads (Figure 24-1), cotton tips, paper, toy parts, crayons (Figure 24-2), eraser tips, food, or organic matter, including sand (Figure 24-3), sticks, and stones.
-
Insects (Figure 24-4).
-
-
Pathogenesis includes some of the key elements of otitis externa (see Chapter 21, Otitis Externa):
-
Initial breakdown of the skin-cerumen barrier (caused by presence of FB).
-
Skin inflammation and edema leading to subsequent obstruction of adnexal structures (e.g., cerumen glands, sebaceous glands, and hair follicles).
-
FB reaction leading to further skin injury.
-
In the case of alkaline battery electrochemical reaction, severe alkaline burns may occur.
