Facial Paralysis in Dogs... Because of "Ear Inflammation"

Ear inflammation alone can cause facial paralysis. Enzo, a 4-year-old Pug, came in with abnormal drooping on the right side of his face, a drooping lip, and an inability to blink. The owner noticed the abnormality and rushed him in for an examination right away.

Why Can Ear Inflammation Cause Facial Paralysis?

The middle ear (Otitis Media) and inner ear (Otitis Interna) are located close to the facial nerve, which controls the muscles of the face. When inflammation becomes severe and spreads, it can compress or damage this nerve, causing the affected side of the face to droop, an inability to blink, and a drooping lip.

Signs to Watch For

A drooping lip on one side, drooling, a drooping eyelid, inability to blink leading to dry and red eyes, a drooping ear on the affected side, and asymmetrical facial movement. This condition is commonly seen in brachycephalic (flat-faced) breeds such as Pugs and French Bulldogs.

What Tests Are Used for Diagnosis?

Since the middle and inner ear are located deep within the skull, they cannot be seen with the naked eye or standard equipment. An accurate diagnosis requires an MRI, which provides highly detailed images that clearly show the location and severity of the inflammation, helping the veterinary team plan targeted treatment.

Can It Be Cured?

Enzo was treated with nerve-supporting medication, antibiotics to treat the infection, and eye care to prevent corneal inflammation caused by the inability to blink. Treatment required collaboration between multiple specialist teams, including the Brain and Spine Center and the Eye Center. Treatment outcomes depend on the severity of the condition and how quickly the pet receives care.
