Under Tongue Impaction

When a Bulge or Protruding Lump is Observed under a Swan’s Chin… it NEEDs Attention.

Normal Swans

As we have been out and about Visiting with Swans and their Owners, we have observed several Swans with these Bulges under their Chins.

Chin Impaction
Some of the Swan Owners thought this was a Tumor..
and there was nothing they would be able to do..

Under Tongue Impaction

Some Swans are prone to this and it becomes a Chronic Problem for them.  Ingesting DRY Fibrous Foods may be a Major Predisposing Factor for Sublinqual Impactions to Form.

Under Tongue Impaction

Some Swans only need help once in a great while to remove this “Stuff.”

Swan Under Chin Impaction

If you Remove the “Wad” of Material when the Bulge under the Chin is Small, the Skin will not Stretch into a Loose Pouch under the Chin.

Chin Impaction

Under Tongue Impactions may occur in both Captive and Wild Swans..  This is easily Visible… A Bulging Pocket under the Chin.

The following SWAN Species seem Prone:
– Cygnus olor – Mute Swan and their Cygnets
– Cygnus atratus – Black Australian Swan and their Cygnets

Mute Swan Flat Chin

The Chin of a Swan should be FLAT…

Some Breeds of Geese with Dewlap are also prone to Impactions.
I have observed some Swans swinging their heads, trying to get this material out..

Under Tongue Impaction
There is likely a WAD of material under the Tongue.. an Impaction.

Chin Impaction

Common Item in the Impaction:

The “STUFF” can be Lots of things found in your Swans World.

Fibrous Grass, Small Roots, Twigs, Fragments of Leaves, Feed, Sand, Soil, Mud, Gravel, Animal Hair, Feather Fibers, String,
etc, etc, etc.   Almost Anything.

Short Fibrous Grass

There seems to be an increased incidence of this when Swans are eating Feed, Plant Material, Grasses and Soil without Water.

Under Tongue Impaction

This “Plug of Junk” under the Tongue can result in increasing difficulty Eating and Drinking.  And Eventually Pressure Necrosis.

Swan Under Tongue Impaction

The Swan affected may slowly Starve.. Weaken and Die..     (Severely Under Weight)

Common Visual Signs include difficulty Swallowing, Ventral
Intermandibular Swelling and Chronic to Severe Impactions.
The Swan below has the Severe Signs..  His Cheeks are Swollen.

Chin Impaction

One Sign the Swan is in TROUBLE is when a Mature Mute Swan has a Flat Knob.  This is a Visual Sign that the Swan is Under Weight..
It is having difficulty Eating.

The Impaction below is a Collection of Roots, Mud, Small Stones, Grass Blades and a few Clover Stems. You can not see the SMELL.

Under Swan Tongue Impaction

This Lodged Material will slowly Ferment, ROT, Support Nasty Bacteria and the Poor Swan will have this Smelly Material Squishing in its Mouth/Beak each time it tries to Eat or Drink.. YUCK !!

Swan Under Chin Impaction

Over Time the Rotting Material may break-down and Invade the underside of the Tongue or the Chin Tissues. This will Result in an infection of the Mouth Tissues.. causing Tissue Pressure Necrosis.
NOT GOOD…

Under Tongue Impaction

At this stage the Swans will definitely need Veterinary Help.. likely Surgery..      Weeks of Recovery with Antibiotics.

DO YOUR BEST to Remove these Impactions when you see them and whenever it reoccurs to reduce Risk of Permanent Dilatation under the Tongue.  If the Impaction is left, or frequently reoccurs, Surgery may be needed to remove the Loose Stretch Skin that fills with Debris easily.

The BIGGEST most Challenging thing you need to do is Catch the Swan.

Having Two People is very helpful…
One to hold the Swan and the other to Remove the Impacted Material.

Under Tongue Impaction

Swans have VERY Little Bite Pressure – Gently Open the Beak.

Swan Under Tongue Impaction
Either lift the Nail or Apply a Little Pressure to the both sides of the Jaw Hinge.

Under Tongue Impaction

Gently PUSH UP under the Chin.. the Material from under the Tongue.    Sweep it out..
(I use my Fingers and Wash Later.)
It is too Risky to use Metal Tweezers – the Swan will not hold Still.
Check that there is nothing left under the Tongue.

Check the Tongue’s Color..  It should be a nice Baby Pink..

If there is any Tissue Damage or Ulcerations on the Tongue or the Skin Pouch Under the Tongue..  This can be Serious…
Check with your Avian Veterinarian for further Treatment Advice.

Chin Impaction

If you have a chance to keep the Swan from eating Short Cut Grass for a while after you remove a Plug.. this may give the stretched “Pouch” time to return to normal..

Floating Salad Greens

Giving Lots of Lettuce or Soft Vegetable Foods on the Pond Water may help reduce the Risk of Re-Impaction..

Under Tongue Impaction

ALSO very Helpful… Try NOT to Cut the Swans’ Grazing Area Very Short…

Longer Grazing Grass

Swans enjoy grazing on Tender Grass Blades..
They need the Vegetation/Plant Material for their Digestive System..

Lawn Clover
And they benefit from the Insects in Grassy Places.
(Crunchy Munchies)

Pennsylvania Meadow Katydid
Consider Alternating the Grass Area you Cut into Three Parts.
Cut One Area this Week.. leave the other Two Areas Grow..

Swan Under Chin Impaction
Then Next Week Cut the longest, Shaggy Area.. leaving the Other Two..
Rotate so there are some Grassy Areas with Longer Tender New Growth..

AS Time Goes By – And We Meet and Visit More Swans
and their Owners..
We SEE more Swans with Under Tongue Impactions..

THIS is a VERY Common Problem with Captive Swans..
Many People who Care for Swans are UnAware..

It Fairly Easy to Correct.  These Swans are Uncomfortable.
The Rotting Material under their Tongue makes Eating Difficult and Nasty..  This can lead to Tissue Destruction under the Tongue.
Infection, Wasting, Starvation to Death.  HELP Your Swans.
