Orofacial pain syndrome
Feline orofacial pain syndrome (FOPS) is a disorder of kittens characterized by both pathological (facial dermatitis, lingual ulcers) and psychological (chronic orofacial hypersensitivity) symptoms.
The cause of this syndrome is unknown but a number of hypotheses have been proposed, including trigeminal nerve neuritis due to FHV, lingofacial pain associated with feline caliciviral infection, and generalized neuritis associated with dental eruptions.
The disease is characterized by an episodic, typically unilateral, discomfort with pain-free intervals. Facial skin lesions have been reported.
Orofacial pain syndrome is often recurrent and with time may become unremitting. Approximately 10% of cases are non-responsive to therapy and require euthansia.
Diagnosis is based on presenting clinical signs, age, duration of symptoms and exclusion of other causes of facial pruritus.
Successful treatment has been reported with use of a combination of anti-inflammatories, opioids and topical lotions, such as:
- famciclovir 125mg 1/4 tablet once a day 8 days
- doxycycline 100mg/g paste 1/3 notch (approx 80mg ) once a day 2 weeks
- buprenorphine 20ug/kg twice a day 10 days
- phenobarbitone 3mg twice a day 10 days
