The best way to prevent labyrinthitis is to prevent contracting an ear infection, though in some cases, this may not be possible. Those with allergic rhinitis—more commonly referred to as allergies—may be more likely to experience labyrinthitis, as their allergies can irritate tissue near the middle ear causing inflammation. Also, an infection of the upper respiratory system that causes swelling and irritation of respiratory tissues can lead to labyrinthitis and may not be easily preventable. However, there are prevention strategies that can help you reduce symptoms, if not avoid them altogether.

Antimicrobial treatment of otitis interna should be given over the long term, 4 to 6 weeks or longer, as antibiotics do not penetrate well into pus-filled tympanic bullae. Systemic antibiotics, preferably based on the results of a bacterial culture and their ability to penetrate the CNS, are recommended. Quinolone antibiotics such as enrofloxacin, ciprofloxacin, and marbofloxacin are common choices. In addition to antibiotic therapy, affected rabbits often benefit from nutritional supplementation, environmental support to minimize the rolling and severe ataxia associated with this disease, and medical therapy with meclizine hydrochloride, an antihistamine that aids in the control of the vestibular disease-associated dizziness and nausea.
What causes otitis media in animals?

Treatment comprises long-term (six to eight weeks) antibiotic therapy. Refractory cases may need surgical drainage of the tympanic bulla. 102,103 Progression to brainstem dysfunction, with the development of central vestibular signs, altered mentation, abnormal posture and gait, cranial nerve deficits, and seizures, may be seen in severe cases. Diagnosis is by MRI and CSF analysis and the prognosis is good to excellent with surgical management and appropriate antibiotic therapy, despite the severe and apparently life-threatening presentation.104
How does otitis media spread?
A primary otitis media may be caused by infection spreading from the upper respiratory tract through the auditory or eustacian tubes; a concurrent sinusitis/rhinitis is suggestive of this pathogenesis. Infection may also spread from the middle ear to the ear canal (if the tympanic membrane ruptures) or to the inner ear, causing vestibular labyrinthitis; it can also sometimes spread to the brain, causing severe neurologic signs, including seizures. (For a more detailed discussion of pasteurellosis and otitis media, see Chapter 16 .) Diagnosis of otitis media/interna is based on clinical signs, aural exam, and imaging, including skull radiography and computed tomography (CT) or magnetic resonance imaging (MRI) where available. Bacterial culture and sensitivity of deep aural or nasal swabs taken under anesthesia are indicated when physical exam supports infection. Endoscopic exam performed under general anesthesia aids in visualizing the distal ear canal and tympanic membrane ( Fig. 19-5 ). In some cases, rabbits with severe otitis media may have soft tissue swelling at the base of the ear canal, apparently a result of the buildup of purulent material within the ear. The diagnosis of encephalitis related to bacterial extension from the middle ear is made histologically.
What is otitis interna?
Otitis interna results from extension of otitis media. It may occur with or without osteomyelitis of the petrous portion of the temporal bone. With time and severity, lesions progress retrograde through the internal acoustic meatus into the cranial cavity, resulting in meningitis, ventriculitis, and encephalitis. Macroscopically, there is typically a middle ear exudate that varies from serosanguineous to suppurative to granulomatous. Microscopically, the inflammatory infiltrate affecting the middle ear is typically composed of neutrophils, macrophages, lymphocytes, and plasma cells. Within the membranous labyrinth, smaller numbers of neutrophils mixed with fibrin can be found in the perilymph (Fig. 20-42 ). Fewer lymphocytes and plasma cells may infiltrate the lamina propria of the osseous labyrinth. The most plausible portal of entry is through the membranous covering of the cochlear window (see Fig. 20-21 ).

What are the functions of the internal ear?
The internal ear consists of a bony labyrinth, cochlea, and the vestibular system. The two main functions of the internal ear are hearing and balance . The cochlea is a small snail-shaped tube filled with fluid and nerve endings going to the brain. It transmits sound impulses to the brain and is responsible for hearing. The vestibular system consists of semi-circular canals, utricles, and saccules. The receptors of the vestibular system sense the rotation of the head and send impulses to the brain. The main function of the vestibular system is to maintain balance .
