I'm sorry to hear about your diffuclties recovering from a facelift. It is not uncommon to have temporary facial nerve injury following a facelift; in fact, this happens in about 1% of patients.
Fortunately for you, facial nerve palsy and facial muscle weakness following a facelift is almost always temporary, with full recovery by 3-6 months. The injury to the facial nerve is usually secondary to stretching or bruising and is unlikely to require futher surgery for repair.
The symptoms you are having, such as asymmetric smile, tearing, and difficulty blinking, are not surprising given the injury. If the asymmetry really bothers you, you could ask your plastic surgeon to give you a little botox on the left side of your face. This will temporarily weaken a few of the facial muscle on the left side of your face, making you a little more symmetric while the right facial nerve recovers.
The most important thing you can do, however, is to be patient and follow up routinely with your plastic surgeon.
