The clinical manifestations of acute otitis media and otitis media with effusion are the result of abnormal eustachian tube function most often caused by inflammation from infection or allergy. The majority of cases involve bacterial infection of the middle ear caused by Streptococcus pneumoniae, Haemophilus influenzae, or Branhamella catarrhalis. Nearly half of all children will have had at least one episode of acute otitis media by 1 year of age, and over 70% by 3 years of age. The signs and symptoms include pain with rubbing or tugging at the ear, fever, irritability, lethargy, and hearing loss. The primary therapy for acute otitis media and otitis media with effusion is antibiotics with the goal of preventing possible complications and providing symptomatic relief. Amoxicillin remains the initial drug of choice in communities where beta-lactamase-producing strains of the common middle ear pathogens are infrequently isolated. If resistant organisms are prevalent, cefaclor, amoxicillin-clavulanate, or cotrimoxazole should be selected. Adjuvant agents such as decongestants have not been shown to provide additional therapeutic benefit. Children who develop chronic otitis media may require prophylactic antibiotic therapy and insertion of typanostomy tubes.

A 7-month-old female llama was examined because of chronic otitis media and externa of 7 months' duration. Radiographically, the tympanic bullae appeared thicker than normal, and the ventral borders were poorly defined; the left external acoustic meatus (ear canal) appeared to be narrower than the right. The llama was treated with penicillin, and the ear canals were lavaged daily. Contrast radiography was performed on day 15 to determine the shape and size of the ear canals and evaluate the integrity of the tympanic membranes. Contrast medium was visible radiographically in the left tympanic bulla, indicating that the left tympanic membrane was ruptured, but the right tympanic membrane appeared to be intact. The left ear canal was narrower than the right, and the bony ear canals had a well-defined sigmoid shape. The right ear improved with medial treatment alone, but the left ear did not. Therefore, lateral ear canal resection was performed. After surgery, however, exudate was still evident in the left ear canal, and the llama became more lethargic and more reluctant to eat. Lateral bulla osteotomy was attempted, but no purulent material was obtained, and curettage of the bulla resulted in hemorrhage. Because of this and because of the llama's poor physical condition, a decision was made to euthanatize the llama. The sigmoid shape of the bony ear canal and the multicompartmental nature of the tympanic bulla make surgical treatment of otitis media and externa in llamas difficult. Further study of surgical treatments for otitis media in llamas is needed.
