| − | Tongue injury in small animals is a relatively common presentation. More commonly so in dogs due to their curious nature, especially regarding food. In large animals, tongue trauma by foreign objects is less common but there are certain diseases such as [[Foot and Mouth Disease|Foot and Mouth disease virus]] and [[Calf Diptheria]] (''Fusobacterium necrophorum''), which cause a sloughing and swelling of the tongue by infection and are incredibly painful.

| − | == Causes of tongue trauma ==
| |
| − | | |
| − | The most common causes of trauma in small animals are:
| |
| − | | |
| − | *'''Lacerations''' e.g. tin cans, cat fights
| |
| − | *'''Penetrating foreign bodies e.g. sticks or bones'''
| |
| − | *'''Linear foreign bodies e.g. string'''- this becomes wrapped around the base of the tongue and as peristalsis carries the rest of the string through the alimentary tract, the caught part cuts deeper into the tongue as this happens.
| |
| − | | |
| − | Other causes of tongue trauma include '''electrical burns '''e.g. from chewing electrical cable, '''chemical burns '''e.g. from caustic agents accidentally consumed, damage due to '''infection''' e.g. [[Feline Herpesvirus 1|feline herpes]], [[Feline Panleucopenia|panleukopanenia]], [[Feline Calicivirus|calicivirus]], fungal or necrotising [[Stomatitis|stomatitis]] or damage due to [[Glossitis|glossitis]] caused by [[Azotaemia|azotaemia]]. In brachycephalic breeds, macroglossia occurs due to the size of the dogs skull and this can occasionally lead to trauma if the tongue is protruding excessively.<br>

| − | '''Always treat the underlying cause'''!
| |
| − | | |
| − | For caustics, you will need to flush the mouth out with water and administer and specific antidotes or treatments for the particular chemical involved. If an infection is the cause of the damaged tongue then of course, treatment of the disease, with palliative care, is required. Electrical burns will also require palliative care (see below).
| |
| − | | |
| − | A '''laceration '''will require either primary surgical repair or second intention healing with sloughing +/- debridement. Amputation can be performed for animals with severe injury or for those with neoplasia of the tongue. Research has shown that animals can function very well with 40-60% of the rostral tongue amputated.
| |
| − | | |
| − | [[Antibiotics]] should always be given following tongue trauma due to the contaminated area of the wound.
| |
| − | | |
| − | Palliative treatment should commence immediately to make the animal more comfortable. Depending on severity of the trauma, animals should either be fed soft food, liquidised food or have a feeding tube (naso-oesophageal, oesophageal, ventricular or enteral) placed if normal feeding cannot be maintained. Anti-inflammatories, usually [[Steroids|corticosteriods]] (unless contraindicated due to surgery) should be immediately prescribed. Cats should be groomed daily as their quality of life will decrease if they are not able to keep themselves clean

Signalment
- Usually young animals that play or chew with cables.
Description
Can be thermal, chemical, or electrical in aetiology and can involve the lips, buccal mucosa and palates as well as the tongue. The injuries sustained vary from mild to severe. Linear scars appear from electrical cable chewing along with discolouring of teeth and burns at the side of the mouth. Ulceration may appear following ingestion of caustic substances
Diagnosis
History
- Cat fight
- Seen playing with or eating a foreign body
- Chewing electric cables
- ingestion of caustics
Clinical Signs
- drooling saliva
- reluctance to eat
- bleeding
- pawing at mouth
- secondary infections
Definitive Diagnosis
Inspection uder a General anaesthetic making sure to check under the tongue for foreign bodies.
Treatment
The animal should be evaluated and treated for systemic involvement, which may be life-threatening in some cases
If contact with a corrosive chemical is seen and the chemical is alkaline, the mouth may be flushed with mild solutions of vinegar or citrus juice; if the chemical is acidic, a solution of sodium bicarbonate may be used. Copious flushing of the mouth with water may help remove some of the chemical substances. More commonly, the animal is seen too long after the exposure for neutralization to be effective.
