This article does not provide aesculapian advice .
ascertain whether facial boldness paralysis is peripheral or central is a key step in the diagnosis(1 ) .
The facial nerve also carries nerve impulses to the tear glands , the saliva glands , and the heftiness of a lowly ivory in the middle of the ear(2 ) .
Who Is At Risk For Bell’s Palsy?
Almost all the people of any age group can be affected by the bell ’s palsy even without prior history or risk factors . But even then , there are few of the risk component that have been link to this condition by widespread enquiry and epidemiological datum .
Firstly , all the cases suffer from diabetes are known to be prone to get this condition . It is perhaps because diabetes can cause widespread nerve damage in any of the nervous tissue belonging to the central or peripheral flighty system . The facial nerve can also get affect bydiabetesand can result in this condition .
Another unwashed risk factor creditworthy for this consideration is the presence of upper respiratory piece of ground infection such as a common cold or flu . It is because these upper respiratory tract infections are related to various flu viruses which are an important risk factor to get migrated to queasy tissue .
Another factor that has been identified to be linked with facial paralysis in pregnancy . harmonise to a study conducted on pregnant women in the United States , it has been found that the pregnant cleaning woman in their third trimester or first calendar week of the postpartum menses are more potential to meet from bell ’s palsy rather than during the whole gestation . The cause and the chemical mechanism responsible for this risk is not known(3 ) .
Is There A Blood Test For Bell’s Palsy?
There is no specific test available for diagnosis of Bell ’s paralysis . A variety of blood run can be ordered to rule out the risk factors and campaign but none of the rake psychometric test is a specific or sensitive marker for bell ’s palsy . Although to rule out risk divisor , various blood trial such as blood glucose , Hba1c , titre for borrelia burgdorferi , herpes virus simplexvirus , mycoplasmapneumonia , antineutrophil cytoplasmatic antibodies , etc . can be done .
The diagnosis is base on the history of the patient and the clinical examination done by a specialist physician . Symptoms of this precondition can be take down and the someone is examined for the presence of the signs such as the absence of closure of one palpebra , deflexion of the lip , absence seizure of nasolabial faithful , inability to bring forth emphasis line on the frontal bone , blowing of air in the lip , inability to clench the teeth the right way , etc . These all signs if present along with the relevant history without any other opening confirm the diagnosing of Bell ’s paralysis .
To affirm this diagnosis , electromyography can be done to encounter out the damage that has been incurred by the facial nerve . It can measure the electrical impulse fade through the cheek and response to it . Other imaging study such as magnetic vibrancy imaging and figure tomography can also be done to rule out other causes of facial deviation such as tumors , cam stroke , etc .
Conclusion
After the far-flung research in this field of operations , there have been numerous endangerment factors that have been name as the grounds of facial muscle paralysis . These jeopardy factors can be found and eliminated by aesculapian treatment so that the chances of arrive this condition are reduced .
Since it is not an infective condition , there is no specific blood test useable for the confirmatory diagnosing . Relevant blood trial run can be done to find out the causal agency and it may also change the dynamics of the compositor’s case . Additional antibiotic or antiviral treatment can be set out along with steroid therapy .
