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. 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. 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. Thorough cleansing of the canal is essential for diagnosis and treatment, but flushing should be avoided. 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. Other prophylactic measures such as drying the ears with a hair dryer and avoiding manipulation of the external auditory canal may help prevent recurrence.

Otoscopic evaluation of the external ear canal and tympanic membrane is the first diagnostic procedure that should be performed in animals presented with otitis externa. It is important to become familiar with the normal structures of the ear to identify any abnormalities. The video otoscope greatly enhances visualization of these structures as well as aiding in retrieval of foreign bodies, biopsy of masses, and performance of a myringotomy. In some cases, a complete otoscopic examination is not possible on the first visit, and the animal may require anti-inflammatory medications or otic flushing to visualize the entire ear canal as well as the tympanic membrane. The purpose of the otoscopic examination is to address the otitis by evaluating the condition of the ear, looking for any masses or foreign bodies; noting the presence, consistency, and color of any exudate; and evaluating the patency of the tympanic membrane. Once a complete otic evaluation has been performed, additional diagnostics as well as a treatment plan can be formulated.

Canine otitis externa and cutaneous pyoderma are common problems that are often associated with Staphylococcus intermedius, Pseudomonas aeruginosa, and Malassezia pachydermatis. In vitro activity of two topical products against these organisms isolated from canine referral patients were evaluated. Organisms were grown and diluted to a concentration equivalent to 10(7) colony-forming units (CFU) per mL and exposed to either a 0 or 1/5 dilution of Hexadene Flush with Spherulites (Virbac Animal Health Inc, Fort Worth, TX) or a 1/5 or 1/25 dilution of ResiCHLOR Lotion with Spherulites (Virbac Animal Health Inc, Fort Worth, TX) at time intervals from 1 to 30 minutes. Results showed that all three organisms were killed within 1 minute of contact time at 0 and 1/5 dilution of the flush. The lotion diluted to 1/5 also killed all three organisms. At 1/25 dilution, this lotion killed S. intermedius and P. aeruginosa within 1 minute of contact time, whereas M. pachydermatis was killed after 1 minute. The findings suggest that the two topical products exhibit efficacy against these common skin pathogens in vitro and can be useful in their clinical management.
