Cranial Helmet

Wearing the Helmet

Apply the helmet, securing the Velcro strap as snug as needed to keep it from moving on the head. Remove the helmet after 4 hours and note any red areas on skin. Any red areas should go away within 30 minutes. When the red marks have diminished, reapply the helmet for 4 more hours. Continue to check skin every 4 hours for the first day. The child may sleep in the helmet on the first day. If no problems arise, leave the helmet on for the prescribed 23 hours with a quick break every 12 hours to check skin. Call our office immediately if there are any signs of skin irritation and we will assess whether adjustments are indicated. It may be necessary to reposition the helmet to maintain its optimal position. Your baby’s head will perspire initially, but this will decrease over 1-2 weeks. The helmet will not cause your child to overheat, but be careful to keep your baby out of extreme temperatures. The helmet should be removed if your baby has a fever. These guidelines may be modified by the orthotist for certain types of plagiocephaly and if this is the case, additional wearing instructions will be provided at the time of fitting.


Caring for the Orthosis

The OS Cranial Molding Helmet is not a protective device. It is not intended to protect a child from high impact trauma or other concussive forces. The helmet is made from a thermoplastic material called Durr Plex, and is padded with P Cell hypoallergenic closed cell foam that will not absorb moisture. Clean the helmet every day (at baby’s bath time) by wiping the inside with rubbing alcohol, followed by rinsing with water. Do not use soap on the helmet because any soap residue can cause skin irritation.


Follow Up Appointments

Return to your physician as directed. Follow-ups with our office must be done on a regular basis as determined by your orthotist to make adjustments in padding for regular growth and to monitor progress.

First follow up appointment: 7 to 10 days after helmet is fit
Next follow up appointment: 2 to 3 weeks later
Subsequent follow-up appointments: every 2 to 4 weeks

The helmet will last from 3 to 5 months, after which time a new helmet may be needed. With proper wearing and follow up, a misshapened head will realign to a more symmetrical shape. Please call our office if you have any questions or concerns during treatment.
