About 350 children are born with craniosynostosis every year in the UK.1,2 In children with this condition, the bones in the skull fuse together too early, causing an abnormally shaped head and leaving no room for the brain to grow. Surgeons try to correct this by creating new gaps, but unfortunately these can join back together and children will often need follow-up operations. Dr Dagan Jenkins at the UCL Great Ormond Street Institute of Child Health aims to find out whether a drug can help improve treatment for children by reducing the need for repeat surgery and improving the appearance of the head.
How are children’s lives affected now?
Children with craniosynostosis can experience persistent headaches, learning disabilities and vision and hearing problems, which are caused by increased pressure within their skull.
To prevent these symptoms, babies often need surgery to correct their abnormal head shape and make room for their brains to grow. But unfortunately, for many children one operation is not enough.
“While current surgical procedures are very effective, they can be complicated and require many hours under general anaesthetic – this is an issue, especially for young babies who may have other medical problems as well,” says Dr Jenkins. “Less invasive procedures have been developed, but these are not currently as effective – and there is also a risk that the gaps may join back together and further surgery will be required.”
“Coping with the news that your baby has such a serious condition is difficult enough, so we really want to improve current treatments so that they are both more effective and reduce the impact on these young lives,” says Dr Jenkins.
How could this research help?
“This is a completely unique study. We hope that applying a drug to the site of surgery will improve the effectiveness of the less invasive procedures without the need for follow-up operations – meaning that affected babies can look forward to a more typical childhood,” says Dr Jenkins.
The team have identified a drug – that is already approved to treat very young children with other conditions – which could also be helpful for treating craniosynostosis by stopping the skull bones from re-fusing.
They now plan to test this drug in a series of experiments in the laboratory, using a new technique that they hope can deliver it specifically to the gaps that the surgeon creates in the skull. “By applying the drug only to where it’s needed, we hope this will greatly reduce the risk of side effects,” says Dr Jenkins.
The researchers hope that the results will lay the foundations to support a clinical trial in patients in the future.
