Overview
The exact pathogenesis of [disease name] is not fully understood.
OR
It is thought that [disease name] is the result of / is mediated by / is produced by / is caused by either [hypothesis 1], [hypothesis 2], or [hypothesis 3].
OR
[Pathogen name] is usually transmitted via the [transmission route] route to the human host.
OR
Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.
OR
[Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].
OR
The progression to [disease name] usually involves the [molecular pathway].
OR
The pathophysiology of [disease/malignancy] depends on the histological subtype.
Pathophysiology
Pathogenesis
- The pathophysiology of Bell' palsy is not known.[1]
Genetics
- There is no established association between genetic factors and Bell's palsy.
- Hereditary components may play a role in familial recurrent Bell's palsy.[2]
Associated Conditions
- Blepharospasm[3]
- Blepharospasm has been rarely seen in patients whit with Bell's palsy.
- In most cases blepharospasm appeared within a month after the onset of Bell's palsy.
Gross Pathology
- On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
Microscopic Pathology
- On microscopic histopathological analysis, thickened perineurium, infiltrates of inflammatory cells between nerve bundles and around blood vessels are characteristic findings of Bell’s palsy.[4]
- It appears that the histology of the facial nerve in Bell's palsy is similar to Herpes Zoster infection, suggestive of an infectious cause.[5]
