Bell’s Palsy – Information for GPs
- Middle ear disease, Ramsay Hunt Syndrome, Parotid Neoplasm, CVA, Trauma
- Children under 16 should always be referred via the on call ENT doctor
- Patients who are pregnant or who have diabetes should also be referred in the same way
If you are confident in excluding all of the above then current evidence suggests that early treatment with prednisolone 25mg bd for 10 days improves the chance of complete recovery to 83% at three months and 94.4% at nine months. A change from previous treatment is that addition of acyclovir actually worsens outcomes so do not give it.
It would therefore be acceptable to start prednisolone and review the patient at one week (to ensure they are no worse) and then at six weeks (to ensure there is improvement). If there is no improvement at six weeks the patient should be referred to ENT as above.
The patient should be warned that dryness of the eye caused by it not closing properly can be a serious complication if left untreated.
If there is incomplete eye closure the lid can be taped close with micropore at night and eye drops such as viscotears should be given four times daily with lacrilube eye ointment at night.
If there is concern about soreness of the eye or decrease in visual acuity the patient should be referred to ophthalmology.
