Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

612
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Muscles for Facial Expressions01:14

Muscles for Facial Expressions

4.7K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Area of Science:

  • Neurology
  • Ophthalmology
  • Otorhinolaryngology

Background:

  • Bilateral facial palsy is a rare condition.
  • Delayed diagnosis and misdiagnosis are common due to its low incidence.
  • Understanding its clinical manifestations is crucial.

Purpose of the Study:

  • To systematically review and evaluate the clinical manifestations of bilateral facial palsy.
  • To identify the causes and recovery patterns associated with this condition.

Main Methods:

  • A systematic literature search was conducted on SCOPUS and PubMed databases up to August 31, 2018.
  • The search term used was 'bilateral facial palsy'.
  • Reference lists of identified studies were also reviewed, and 10 studies involving 75 patients were analyzed.

Main Results:

  • Bilateral facial palsy accounts for 0.3% to 2.0% of all facial nerve palsy cases.
  • Causes are diverse, with 51% associated with other cranial nerve involvements.
  • Complete recovery was observed in 80% of patients, with 20% experiencing incomplete recovery.

Conclusions:

  • Bilateral facial palsy presents with varied etiologies.
  • The prognosis for recovery from bilateral facial palsy is generally favorable.
  • Further research may elucidate specific etiological factors and optimize treatment strategies.
