When plagiocephaly is left untreated, sports helmets will not fit properly. And if the ears do not align, wearing glasses may be difficult.
With asymmetric plagiocephaly, Tracy says, children can have issues with crossbite, which can lead to trouble breast feeding; temporomandibular joint disorder, which causes the jaw to have painful clicking when the mouth opens and closes; and an increase in ear infections due to the misalignment of the ears’ drainage tubes.
The functional issues with brachycephaly are a bit more significant, and include underbites, increased ear infections and problems with sleep apnea or snoring.
“Basically what happens is the compression of the length is also compressing everything inside the skull, so the airway goes from being circular to oblique,” Tracy says. “So basically they are not able to get as much air flow in and out. And obviously if you have sleep problems as a baby it can affect your learning.”
Generally, plagiocephaly is caused by lack of “tummy time,” which is in correlation to the SIDS campaign and convenience devices such as car seats, strollers and cradle swings, Tracy says.
Lack of tummy time is also attributed to developmental delays such as motor skills, rolling over and crawling, according to a survey of pediatric physical and occupational therapists. The survey was done for Pathways Awareness, a nonprofit dedicated to early detection of motor delays in children.
Another cause of plagiocephaly is torticollis, which occurs when a baby’s neck is weak on one side and tight on the other, causing him to favor a side when he lies down, Tracy says.
The baby’s position in the womb, especially in cases of twins, triplets and other multiples, also can affect the head shape because space is restricted. And premature babies are at a higher risk of developing plagiocephaly because their skulls are not as thick, Tracy says.
Babies can only be treated at CranialTech until they are 18 months old, because the skull is continuously thickening and after a certain point the plagiocephaly becomes untreatable, Tracy says.
They prefer to see the child ages 4 to 6 months because the child has exponential head growth during the first 12 months.
