[Guest guest]

Can anyone help me better understand these measurements that the tech gave to my husband.

Right anterior -----> Left posterior 150 on 09-02-10

Right anterior------>Left posterior 153 on 10-07-10

" " 153 on 10-21-10

Left Anterior------->Right Posterior 130 on 09-02-10

" " 138 on 10-07-10

Cranial Vault Asymmetry 20 on 09-02-10

" " " 15 on 10-07-10

" " " 12 on 10-21-10

Are these good results??? The cranial vault asymmetry of 20. is that considered Severe Plagiocephaly? I keep seeing people writing that their child has 6mm plagio etc. Does this mean my son started with 20mm??
