QUESTION

A 45-year-old male with no known PMH presents with a complaint of left facial weakness onset 2 hours prior to hospital arrival. He endorses associated symptoms, including facial numbness and change in taste.

Answer the following questions:

1. Subjective:
   • What other relevant questions should you ask regarding HPI?
   • What other medical history questions should you ask?
   • What other social history should you ask?
2. Objective:
   • Differentiate the sign and symptoms of bells palsy and trigeminal neuralgia
   • What tests or procedures (Lab or Diagnostic) would you perform or order for this patient?

3. Diagnosis:

• What are the top 3 differential diagnoses you would consider for this patient, and what is your rationale?
• What is the patient final diagnosis?

4. Plan:

• What is the gold standard treatment for this patient?

ANSWER

Subjective

Other relevant questions regarding HPI
Does the patient have any history of recent infections, such as cold or flu?
Has the patient experienced any recent trauma or injury to the face or head?
Is there a history of any viral infections, such as herpes simplex virus, in the past?
Has the patient experienced any recent stress or emotional events?
Are there any other neurological symptoms, such as headache, dizziness, or changes in vision?

Other medical history questions
Does the patient have a history of any chronic medical conditions, such as diabetes or hypertension?
Is there a family history of neurological disorders or facial weakness?
Has the patient had any previous episodes of facial weakness or similar symptoms?

Other social history
Does the patient smoke or consume alcohol regularly?
Is the patient under any significant stress at home or work?
Does the patient have any recent travel history?

Objective

Differentiate the signs and symptoms of Bell’s Palsy and Trigeminal Neuralgia

Bell’s Palsy
Sudden onset of unilateral facial weakness or paralysis, typically affecting the lower half of the face.
Associated symptoms may include facial numbness, altered taste sensation, increased sensitivity to sound, and difficulty closing the eye on the affected side.
No other neurological deficits are present, and the patient can usually move the forehead muscles.

Trigeminal Neuralgia

Sudden, severe, and recurrent episodes of sharp, shooting, or electric shock-like pain along the distribution of the trigeminal nerve (usually affecting one side of the face).
The pain is triggered by various stimuli, such as touch, chewing, or cold wind.
There is no associated facial weakness or paralysis.

Tests or Procedures

For this patient, the following tests or procedures would be performed:

Physical examination to assess the extent of facial weakness, check for sensory deficits, and evaluate cranial nerve function.
Imaging studies such as MRI or CT scan to rule out other possible causes of facial weakness, such as stroke or tumors.
Blood tests to check for signs of infection or other systemic conditions.

Diagnosis:

Top 3 differential diagnoses

Bell’s Palsy: This is the most likely diagnosis due to the sudden onset of unilateral facial weakness and associated symptoms, such as facial numbness and taste changes. The absence of other neurological deficits supports this diagnosis.

Trigeminal Neuralgia: Although the patient does not present with facial weakness, the complaint of facial numbness and sharp, shooting pain raises the possibility of trigeminal neuralgia.

Stroke: Given the sudden onset of facial weakness and associated symptoms, a stroke must be ruled out as a potential cause, especially if there are risk factors such as hypertension or a family history of stroke.

Patient’s Final Diagnosis

Based on the assessment and ruling out other possible causes, the patient’s final diagnosis is Bell’s Palsy.

Plan

Gold standard treatment for Bell’s Palsy

Corticosteroids (e.g., prednisone) are considered the gold standard treatment for Bell’s Palsy. They help reduce inflammation and swelling of the facial nerve, improving symptoms and promoting recovery.
Antiviral medications (e.g., acyclovir) may be considered if there is evidence of viral infection or herpes simplex virus involvement.
Supportive measures, such as eye protection and lubrication, may be prescribed to prevent corneal damage in case of facial weakness affecting eye closure.
Physical therapy and facial exercises may be recommended to maintain muscle tone and prevent long-term complications.

In conclusion, this 45-year-old male’s presentation of sudden-onset left facial weakness with associated facial numbness and change in taste raises concerns for Bell’s Palsy. The differential diagnosis includes trigeminal neuralgia and stroke, but the absence of other neurological deficits supports the diagnosis of Bell’s Palsy. The gold standard treatment involves corticosteroids and antiviral medications, along with supportive care to promote recovery and prevent complications. Early diagnosis and appropriate management are essential for favorable outcomes in cases of Bell’s Palsy.
