A tympanic membrane that has normal color and mobility is not typical for acute otitis media. The tympanic membrane is normally mobile, translucent, and intact. 5, 8 Detection of a middle ear effusion with moderate to severe bulging of the tympanic membrane, new-onset otorrhea not caused by otitis externa, or mild bulging of the tympanic membrane with recent onset of ear pain (less than 48 hours), especially with erythema, is key in the diagnosis of acute otitis media. Specific otoscopic examination findings for the etiology of otalgia are listed in Table 1 5, 7 and Table 2. Physical examination should include inspection of the auricle and periauricular region, as well as an otoscopic examination to visually inspect the tympanic membrane and the external auditory canal. The physician should start the examination by asking the patient to localize the pain, which may reveal a secondary cause (e.g., localization to the temporomandibular joint, myofascial pain localized to the mastoid process). When risk factors for malignancy are present (e.g., smoking, alcohol use, diabetes mellitus, age 50 years or older), computed tomography, magnetic resonance imaging, or otolaryngology consultation may be warranted. Otalgia may be the only presenting symptom in several serious conditions, such as temporal arteritis and malignant neoplasms. History and physical examination usually lead to the underlying cause however, if the diagnosis is not immediately clear, a trial of symptomatic treatment, imaging studies, and consultation may be reasonable options. Primary otalgia is more common in children, whereas secondary otalgia is more common in adults. The most common causes of secondary otalgia include temporomandibular joint syndrome and dental infections. Pain that originates outside the ear is called secondary otalgia, and the etiology can be difficult to establish because of the complex innervation of the ear. Examination of the ear usually reveals abnormal findings in patients with primary otalgia. Pain that originates from the ear is called primary otalgia, and the most common causes are otitis media and otitis externa. Other prophylactic measures such as drying the ears with a hair dryer and avoiding manipulation of the external auditory canal may help prevent recurrence.Otalgia (ear pain) is a common presentation in the primary care setting with many diverse causes. Acidification with a topical solution of 2 percent acetic acid combined with hydrocortisone for inflammation is effective treatment in most cases and, when used after exposure to moisture, is an excellent prophylactic. Thorough cleansing of the canal is essential for diagnosis and treatment, but flushing should be avoided. ![]() Excessive moisture and trauma, both of which impair the canal's natural defenses, are the two most common precipitants of otitis externa, and avoidance of these precipitants is the cornerstone of prevention. The most characteristic symptom is discomfort that is limited to the external auditory canal, while the most characteristic signs are erythema and swelling of the canal with variable discharge. Otitis externa is most commonly caused by infection (usually bacterial, although occasionally fungal), but it may also be associated with a variety of noninfectious systemic or local dermatologic processes. ![]()
