According you question and sample there is what you want.

The idea is:

1. Get the string before PermanentWordChangeWord.. The rule for this is (.*)PermanentWordChangeWord\.

2. Get the value after PermanentWordChangeWord. but before .(dot). The rule for this is ([^\..]*) this mean match all but without .(dot)

var text = "xxxPermanentWordChangeWord.myname.city.year.age";
var pattern = @"(.*)PermanentWordChangeWord\.([^\..]*)";
Regex reg = new Regex(pattern, RegexOptions.IgnoreCase);
Match match = reg.Match(text);

var output = string.Empty;
if (match.Success)
{
    var group0 = match.Groups[0].Value; // This value is: xxxPermanentWordChangeWord.myname.city.year.age
    var group1 = match.Groups[1].Value; //This value is:  xxx
    var group2 = match.Groups[2].Value; //This value is: myname

    output = group1 + group2;
}
