Y1 - 2016 N1 - T2 - Tintinalli’s Emergency Medicine: A Comprehensive Study Guide, 8e AB - Ear pain, or otalgia, is one of the most common pediatric outpatient chief complaints. The differential diagnosis is listed in Table 118-1. This chapter discusses acute otitis media, otitis media with effusion, otitis externa, acute mastoiditis, and foreign body. Anatomically, the ear is divided into three major parts: (1) the outer ear, which includes the auricle and the external auditory canal; (2) the middle ear, which is bound by the tympanic membrane laterally, contains the auditory ossicles, and is connected to the nasopharynx via the eustachian tube; and (3) the inner ear, which includes the semicircular canals, the cochlea, and the auditory nerve (Figure 118-1).
