Ear mites are mites that live in the ears of animals. The most commonly seen species in veterinary medicine is Otodectes cynotis (Gk. oto =ear, dectes =biter, cynotis =of the dog). This species, despite its name, is also responsible for 90% of ear mite infections in felines. In veterinary practice, ear mite infections in dogs and cats may ...
Eustachian tube dysfunction can be caused by a number of factors. Some common causes include the flu, allergies, a cold, and sinus infections. [6] In patients with chronic ear disease such as cholesteatoma and chronic discharge, studies showed that they have obstructive pathology at the ear side of the Eustachian tube. [7][5] Given that ...
Cochlear hydrops refers to an increase in endolymphatic fluid in the inner ear. This build-up is either due to an overproduction or insufficient drainage of endolymph in the constant regulation of fluid in the inner ear. Usually, only one ear is affected. The root cause of the process is unclear and may vary from patient to patient, but can ...
Feline arterial thromboembolism (FATE syndrome) (German: Feline arterielle Thromboembolie) is a disease of the domestic cat in which blood clots (thrombi) block arteries, causing severe circulatory problems. Relative to the total number of feline patients, the disease is rare, but relatively common in cats with heart disease: about one-sixth of ...
A labyrinthine fistula is an abnormal opening in the inner ear. This can result in leakage of the perilymph into the middle ear. [1] This includes specifically a perilymph fistula (PLF), an abnormal connection between the fluid of the inner ear and the air-filled middle ear. This is caused by a rupture of the round window or oval window ...
The styloid process is a slender and pointed bony process of the temporal bone projecting anteroinferiorly from the inferior surface of the temporal bone [1] just below the ear. [citation needed] Its length normally ranges from just under 3 cm to just over 4 cm. It is usually nearly straight, but may be curved in some individuals.
Otitis externa is an inflammation of the outer ear and ear canal. Animals are commonly prone to ear infection, and this is one of the most common manifestations of allergy in dogs. In dogs, those breeds with floppy ears are more prone, since air flow is limited and a warm, moist environment built up, which is conducive to infection.
Mastoiditis is the result of an infection that extends to the air cells of the skull behind the ear. Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside [1] the mastoid process. The mastoid process is the portion of the temporal bone of the skull that is behind the ear.
