Letter to The Editor
The term helmet therapy refers to conservative (non-surgical) treatment of infantile cranial deformities. Infantile cranial deformities can result from premature bony closure of the cranial sutures (premature suture synostoses) [1-5]. The incidence is reported to be about 1: 2,500 births [3,4]. Such early ossification can lead to quite different, sometimes bizarre skull shapes and also occurs in the context of circumscribed malformation syndromes (e.g. Crouzon syndrome, Apert syndrome).
