HI, thanks for using healthcare magic
Checking the position of the uvula
evaluates the 9th cranial nerve
(the glossopharyngeal nerve
Deviation of the uvula may indicate abnormal function of this nerve though it can occur in other scenarios such as infected tonsil
pushing the uvula.
If she had issues with this nerve she would likely have problems with speech and swallowing. Since she is other wise well, it is not likely anything to worry about.
I hope this helps
