What is it?

Ear abscess is a very common middle ear infection in the Greek tortoise (Testudo graeca) and other terrestrial turtles. Unlike mammals, the turtle does not have a visible external ear canal: the ear is covered by a smooth tympanic membrane, located just behind the eye, on each side of the head. When an infection takes hold in the middle ear, the pus produced does not drain like it does in a dog or cat. In reptiles, the pus is thick, caseous, almost solid, like cheese. It therefore accumulates on site and forms a rounded mass which deforms the tympanic membrane, visible under the skin as a firm ball on one side of the head, sometimes on both sides.\n\nThis condition affects both turtles raised in captivity in Tunisia and those kept in a garden, and remains one of the most common causes of consultation in terrestrial reptiles.

The most visible sign is a firm, round swelling on the side of the head, just behind the eye, on one side or sometimes both sides at once. The skin covering this bump may appear tight, slightly bulging, and sometimes discolored.\n\nThe turtle may appear embarrassed, less active, less lively than usual. She may eat less well or refuse to eat. Some turtles tilt their heads slightly to the affected side or seem to misjudge distances, bumping against the walls of their enclosure or objects, especially if both ears are affected.\n\nIn more advanced cases, the infection can spread to the throat, mouth or even the respiratory system, with difficulty breathing or more marked lethargy.

Causes and risk factors

Ear abscesses are almost always of bacterial origin. The bacteria responsible are most often those already present naturally in the environment or the turtle's mouth, which take advantage of a drop in immune defenses to infect the middle ear, probably via the Eustachian tube which connects the throat to the ear.\n\nThe underlying cause, almost always found, is a deficiency in vitamin A. This deficiency weakens and modifies the covering tissues of the entire body, including those which line the Eustachian tube and the middle ear, which makes it easier for the infection to take hold. A diet poor in green vegetables and rich in fruits or unsuitable industrial foods is the most common cause.

An unbalanced diet, too rich in sweet fruits and low in leafy green vegetables, promotes vitamin A deficiency which causes the disease.\n\nUnsuitable living conditions also play a role: insufficient temperature or humidity, lack of exposure to ultraviolet light, chronic stress, poorly maintained enclosure or promiscuity with other sick turtles.\n\nAn immune system weakened by another chronic illness, digestive parasitism or poorly managed wintering also increases the risk.

Diagnosis and care

Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.

The veterinarian makes the diagnosis by direct observation of the characteristic bump behind the eye, supplemented by a general examination of the turtle. An x-ray can be useful to assess the extension of the infection towards the bones of the skull.\n\nIn certain cases, a pus sample is taken to identify the bacteria in question and guide the choice of the most appropriate antibiotic treatment.

Treatment

The standard treatment is surgical: the veterinarian opens the tympanic membrane under anesthesia or sedation to completely remove the mass of solid pus, which cannot be resorbed by medications alone.\n\nAn antibiotic treatment is generally associated, chosen if possible according to the results of an analysis of the pus taken. A vitamin A intake, in an adapted form and supervised by the veterinarian, is also established to correct the underlying cause and prevent recurrences.\n\nLocal care of the wound and a more general correction of diet and living conditions complete the treatment.

Treatment depends on the cause and the animal's condition: it must be determined by a veterinarian. No self-medication.

Prevention

Prevention is based above all on a suitable and varied diet, rich in leafy green vegetables and low in fruit, which covers the turtle's vitamin A needs.\n\nA properly heated habitat, with access to a quality ultraviolet source suitable for reptiles, and good hygrometry limit stress and support the animal's natural defenses.\n\nRegular veterinary monitoring, including in a turtle that appears healthy, makes it possible to identify any nutritional imbalance early before it appears. of complications.

Possible complications

Without treatment, the infection can spread to the skull bones, throat, or airways, causing more serious and more difficult to treat complications.\n\nProlonged bilateral disease can affect the turtle's balance and orientation. The underlying vitamin A deficiency, if not corrected, also puts people at risk for other disorders such as eye problems or increased susceptibility to other infections.

When to see a veterinarian

A firm bump or swelling appears on one or both sides of the head, behind the eye.

The turtle is eating less well or has been refusing to eat for several days.

The animal seems depressed, less active, or bumps against objects in its enclosure.

The turtle tilts its head or appears to have lost its balance.

Difficulty breathing or swelling around the mouth appears.

Prognosis

The prognosis is generally good when the abscess is managed early with surgery and the underlying nutritional cause is corrected. Without surgical treatment, the infection does not heal spontaneously and may gradually get worse. Recurrences are possible if the dietary imbalance is not permanently corrected.

Frequently asked questions

Can an ear abscess go away on its own in a turtle?

No. Pus in reptiles is thick and caseous, almost solid. It cannot be reabsorbed naturally or drained without veterinary intervention. Surgery is required to remove it.

Why did my turtle develop this ear abscess?

The most common cause is a lack of vitamin A in the diet, often linked to an excess of fruit and a lack of green vegetables. This deficit weakens the tissues and favors the establishment of a bacterial infection.

Is the operation dangerous for a turtle?

This is a common procedure in reptiles, performed under anesthesia or sedation by a veterinarian experienced with turtles. It remains generally well tolerated if the turtle is properly taken care of before and after.

How to prevent the abscess from returning after the operation?

It is necessary to permanently correct the diet by providing a variety of green vegetables and limiting fruits, improve access to ultraviolet light and the temperature of the enclosure, and follow the veterinarian's recommendations regarding a possible vitamin A intake.
