I had an infection after genioplasty. Is fully recovery possible?

Nerve injury and recovery depends on a number of variables.
We usually describe nerve injuries as neurapraxia, which is categorized in different levels of degrees from one to five.
Depending on the level of nerve injury, and the distance from the point of injury to the peripheral receptors will determine the potential recovery and the timeframe.
The time for recovery also depends on if the underlying problem is still present or not.
If there’s persistent, swelling and pressure against the nerve, then the chance and timeframe of recovery is worse.
Likewise, if the nerve has been transfected, the recovery and quality of recovery is going to be worse.
No one can give you a definitive answer, and the degree of neurapraxia is sometimes only revealed by when things return to normal.
if neurapraxia is due to the surgical intervention, then the surgeon may have some insight based on what was done, including the proximity to the nerve itself.
If the neurapraxia was due to inflammation from the infection, then the timeframe of when the infection was cleared up and the degree of inflammation from the infection will impact the recovery.
There is no real straightforward answer to your question because it depends on the number of variables that we may not be able to decipher.
I suggest you read up on the different levels of neurapraxia to get a general understanding of nerve injuries and their recoveries.
