As per defination microcephaly it is head circumferencemore than 3 sd below for that age & sex.

ONE SINCERE REQUEST IS CAN YOU GIVE ANY phone no on which we can directly call you .it may save my time to some extent .Thanks a lot .JOB OPP IS REALLY A GOOD IDEA

As you have correctly pointed out, there is no growth chart that shows the 3rd standard deviation including the latest NCHS charts which give upto the 3rd percentile. However, you can try the various anthropometry charts in the "TEXTBOOK OF MALFORMATIONS' by Smith in which you have charts for testicular volume, hand span, ear span and head circumference.
