Causes
- Lacerations e.g. tin cans, cat fights
- Penetrating foregin bodies e.g. sticks or bones
- Linear foregin bodies e.g. string
- Electrical burns e.g. from chewing electrical cable
- Chemical burns e.g. from caustic agents
- Damage due to infection e.g. feline herpes, panleukopanenia, calicivirus, fungal or necrotising stomatitis
- Damage due to glossitis caused by azotaemia
- Macroglossia- if too large may become traumatised by teeth etc (common in brachycephalics)
Diagnosis
History
- Cat fight
- Seen playing with or eating a foreign body
- Chewing electric cables
- ingestion of caustics ETC
Clinical Signs
- drooling saliva
- reluctance to eat
- bleeding
- pawing at mouth
- secondary infections
Definitive Diagnosis
Inspection under a general anaesthetic making sure to check under the tongue for foreign bodies.
Treatment
- Caustic chemicals: exagerated flushing of the mouth with water
- Lacerations: Primary surgical repair or second intention healing with sloughing +/- debridement
- Amputation: if severe injury. Animals can function very well with 40-60% of the rostral tongue amputated
- General: Antibiotics, palliative treatment aimed at reducing oral discomfort including anti-inflammatory drugs, mainly corticosteroids. Assisted feeding (Naso-oesophageal, oesophageal, ventricular or enteral) should be used if normal feeding cannot be maintained
Prognosis
Dependent on cause and severity.
