Can Bell's Palsy causes eye bag?

Yes, it is entirely possible that your bells palsy is behind your recent under eye bag. My advice would be to give your body the time to heal and then reassess your under eye bags in another month or two. If you still don't like the way things look, schedule a consultation with a board certified plastic surgeon to discuss using filler under the eye to reduce the "bag". My best,

I’m sorry to hear that you are going through this. From the sounds of it, your Bell’s palsy diagnosis was fairly recent, so it’s important to wait and give your body time to heal on its own. As long as you had taken the initial antiviral and steroid medication that was most likely prescribed, chances are you will make a full recovery naturally. Since your diagnosis was just 2 months ago, it’s possible that the changes that you notice in your face are due to your body going through the healing process. Often times, patients start to experience synkinesis which is a discoordination of the facial muscles, which could be what you are beginning to notice when you make certain facial expressions as you mentioned. I would recommend scheduling an appointment with a facial nerve specialist to establish yourself as a patient, and begin to explore your options for future treatment. There are very few physicians world-wide who specialize in helping patients with Bell’s palsy. I see patients with different types of facial nerve damage from all over the world, and would be happy to discuss the details of your case with you during a consultation. Best of Luck!

Bells palsy causes alteration of the facial features and can make the eyes appear more tired. This can be treated with lasers, fillers, microneedling/PRP.  Best, Dr. Emer.

Yes it can. The tissue that prevent the orbital fat prolapse thin out with age which results in under eye bags. That process is significantly advanced with Bells palsy since it affects the muscle.

Bell's palsy is caused by a latent herpes virus reactivation in a sensory facial nerve causing  weakness of the motor nerve to the face.  The ultimate recovery of the facial function is complete in 85% of individuals.  You still have further time (4-10 months) for additional recovery of function.  Bell's palsy causes drooping of the lower eyelid and inhibition of upper eyelid complete closure. Buldging of the eyelid could be do to the droopiness of the lower lid but would not be due to fat.  Be patient for the complete healing to be achieved. 

Hi there, It does sound like the eye bag you are seeing is a result of Bell's palsy. The muscle that holds the lower eyelid in its position is likely weak. The good thing, is that you are still early in your recovery from Bell's. It is still possible for the to resolve are the strength returns to your face with movement. Consider going to a physical therapist with experience in facial paralysis.Give yourself 6 months to a year before you decide if the eye bag resolved. If you are still bothered by it, consider a consultation with a surgeon. Hope this helps! 

Hello Lock12,Yes, any facial nerve weakness can lead to a bag on that side.  The reason is that there is a muscle around your eye controlled by that nerve.  With weakness of the nerve, the muscle becomes weaker.  This can allow the fat that is held back behind that muscle to begin to push through and be more visible.  It can take awhile after Bell's palsy to get your full recovery.  You can consider fillers to temporize the appearance of the bag.  After a year if you still have the asymmetry, you can consider surgery to address that one side.  Now if your eyelid is falling away from your eyeball, that should be addressed sooner.  I don't think that is your case beucase you said at rest everything looks the same.  If you want to imporve the symmetry of your brow and nose you can use Botox on the good side to make them look more like the side that is affected.  I hope this helps and good luck.
