Suffering from sudden weakness of one side of face? Beware! There might be problem of a special type of facial paralysis

Bell's palsy facial paralysis

A team of doctors in a research revealed that a sudden weakness of one side of face and difficulty in closing one of the eyelids can be a type of facial paralysis. The team also stated the type as Bell’s Palsy, which results in n inability to control the facial muscles on the affected side.

As per the research, around 80 percent patients of Bell’s palsy recover within a duration of six months, if treated properly and on time.

“Difficulty in facial expression, alteration in sense of taste and pain in the front or behind the ear in some cases are also symptoms that give indications that it might be Bell’s Palsy,” said ophthalmologist Samir Sud. “The most common effect of Bell’s palsy on eye is that the patient is unable to blink on the affected side and close the eyelids completely. Sometimes lower eyelid may turn outwards,” he said.

“Proper care of eye during this period is of utmost importance to prevent permanent consequences such as corneal ulceration and scarring leading to loss of vision,” said Anurag Wahi, an Ophthalmologist at Sharp Sight Group of Eye Hospital.

Wikipedia noted that Bell’s palsy is a type of facial paralysis that results in an inability to control the facial muscles on the affected side. Symptoms can vary from mild to severe. They may include muscle twitching, weakness, or total loss of the ability to move one or rarely both sides of the face. Other symptoms include drooping of the eyelid, a change in taste, pain around the ear, and increased sensitivity to sound. Typically symptoms come on over 48 hours.

Doctors also suggest several symptoms of the disease, which mostly people ignore. However, later they discover themselves to be suffering from Bell’s Palsy, Wahi said in his statement. Irritation in the eyes due to dryness or drooping of part of the face are also included in these symptoms.

The cause of Bell’s palsy is unknown. Risk factors include diabetes and a recent upper respiratory tract infection. It results from a dysfunction of cranial nerve VII (the facial nerve). Many believe that this is due to a viral infection that results in swelling. Diagnosis is based on a person’s appearance and ruling out other possible causes. Other conditions that can cause facial weakness include brain tumour, stroke, Ramsay Hunt syndrome, and Lyme disease.
