From the Guidelines

Bec face is not a recognized medical term, and without more context, it's difficult to provide specific information about what it might mean. If you're asking about a facial condition, treatment, or specific medical term, I would need more details to provide an accurate answer. Some possible related terms include Bell's palsy, which is a condition that causes facial paralysis or weakness, as discussed in the clinical practice guideline by 1. The guideline recommends that clinicians should assess the patient using history and physical examination to exclude identifiable causes of facial paresis or paralysis in patients presenting with acute-onset unilateral facial paresis or paralysis, as stated in 1 and 1. Key points to consider when evaluating a patient with facial weakness or paralysis include:

  • Bell’s palsy is rapid in onset (<72 hours) 1
  • Bell’s palsy is diagnosed when no other medical etiology is identified as a cause of the facial weakness 1
  • Clinicians should prescribe oral steroids within 72 hours of symptom onset for Bell’s palsy patients 16 years and older, as recommended by 1 and 1
  • Clinicians should implement eye protection for Bell’s palsy patients with impaired eye closure, as stated in 1 and 1 If this is related to a social media trend or colloquial expression, meanings can vary widely depending on the community or platform where it's used. In any case, if you are experiencing facial weakness or paralysis, it is essential to consult a healthcare professional for proper evaluation and treatment, as emphasized by 1, 1, 1, and 1.

From the Research

Bell's Palsy Description

  • Bell's palsy, also known as idiopathic facial paralysis, is a neuropathy that affects the seventh cranial nerve, the facial nerve 2.
  • Its presentation is unmistakable by a trained clinician, usually presenting with unilateral facial weakness, reduced forehead wrinkling, nasolabial fold flattening, drooping of the corner of the mouth, and drooling 2.

Diagnosis and Treatment

  • The diagnosis of Bell's palsy relies on knowledge of the anatomy and function of the various motor and nonmotor components of the facial nerve 3.
  • Corticosteroids have been shown to be effective in treating Bell's palsy, with a significant reduction in incomplete recovery of facial motor function six months or more after randomisation 4, 5.
  • The addition of an antiviral to steroids may increase the likelihood of recovery, but only by a very modest effect 3.
  • Thorough ENT and neurological clinical examination is recommended in all patients presenting with peripheral facial palsy to confirm diagnosis of Bell's palsy 6.

Prognosis and Recovery

  • Even without treatment, the outcome of Bell's palsy is favorable, but treatment with corticosteroids significantly increases the likelihood of improvement 3.
  • Most patients will recover fully within six months regardless of the treatment 2.
  • The number of people who need to be treated with corticosteroids to avoid one incomplete recovery was 10 (95% CI 6 to 20) 4.

Management Guidelines

  • The French Society of ENT and Head and Neck Surgery (SFORL) guidelines recommend corticosteroid therapy as early as possible (ideally within 72h) at a dose of 1mg/kg/day for 7-10 days 6.
  • Antiviral therapy should be associated with steroids in patients with severe and early-onset disease and in Ramsay-Hunt syndrome 6.
  • Isolated antiviral therapy is not recommended 6.
