What is the tympanic bulla?
The tympanic bulla (Bulla tympanica) is placed medially to the styloid process. This rounded prominence belongs to the pars tympanica and in great part, in Cats, to the endotympanic part. It is hollow, pneumatised by diverticules of the ear drum forming the multiple cells generally separated by very thin bony septums.
Do dogs have tympanic membranes?
Unlike humans that have a very short ear canal, dogs have a long narrow ear canal that makes almost a 90 degree bend as it travels to the deeper parts of the ear. The outer ear cannel is separated from the middle ear by a thin membrane called the eardrum or tympanic membrane.
Where is the ear pinna on a dog?
The outer ear includes the pinna (the part you see that is made of cartilage and covered by skin, fur, or hair) and the ear canal. The pinna is shaped to capture sound waves and funnel them through the ear canal to the eardrum. In dogs, the pinnae are mobile and can move independently of each other.
Can a dog hear after a TECA?
Some dogs are able to hear sounds at normal volumes after the TECA surgery. It is not possible to predict how much more hearing loss an individual will experience after TECA.
What is the location of the auditory tube?
The Eustachian tube is located in the para-pharyngeal space and is closely linked to the infratemporal fossa. The Eustachian tube continues from the front wall of the middle ear to the sidewall of the nasopharynx, progressing along the posterior edge of the medial pterygoid plate.
Where is the tympanic plexus?
In the middle ear, the tympanic plexus is formed on the tympanic promontory by branches of Jacobson's nerve (tympanic branch of the glossopharyngeal nerve) and caroticotympanic nerves originating from the internal carotid artery plexus.
What is the tympanic membrane in dogs?
By Ryan Llera, BSc, DVM; Ernest Ward, DVM. The tympanic membrane or eardrum is a thin membrane that separates the outer ear canal from the middle and inner ear. The middle ear contains the three tiniest bones in the body, the malleus, incus and stapes, more commonly referred to as the hammer, anvil, and stirrup.
What does Henry's pocket dog?
This little fold or slit in dog ears is known as a Henry's pocket. ... The less-cute but more scientific name for it is the cutaneous marginal pouch. It's found in cats and some dog breeds. It's located on the lower posterior part of the external ear, if your dog has it.
What is the black stuff in my dog's ear?
The presence of yeast, bacteria, or both confirms an ear infection diagnosis. Dogs with yeast-related ear infections often have dark brown or black debris in the ears. Dogs with bacterial ear infections may have yellow-brown debris or pus in the ears.
What are the parts of a dogs ear?
The canine ear consists of the pinna, external ear canal, middle ear and inner ear. The external ear is composed of auricular and annular cartilage. The auricular cartilage of the pinna becomes funnel shaped at the opening of the external ear canal.
Where is the cochlear?
Cochlea: overview. The cochlea represents the 'hearing' part of the inner ear and is situated in the temporal bone.
What is the inside of a dog's ear supposed to look like?
A normal ear canal should appear a pale pink colour, it may have a little wax but should generally be quite clean and not smelly (it may smell a little waxy but not offensive). It should not be moist.
Why does my dog keep shaking his head and scratching his ear?
Otitis externa, otherwise known as inflammation of the ear canal, affects roughly 20% of dogs. A dog with otitis may scratch his ears, shake his head vigorously and frequently, hold his ears in an abnormal position, and/or have malodorous ear discharge. The ears are also usually painful when touched.
Does a TECA cause deafness?
TECA surgery on both sides can sometimes be required and this can result in significant loss of hearing sensitivity.
Is a TECA surgery worth it?
Fundamentally, the TECA is a very rewarding surgery for the patient, owner, and veterinarian. Most owners report a dramatic improvement in the attitude of their pets postoperatively, claiming they see a return of social and play behaviors they have not seen in many years.
