title: Posterior skull surgery in craniosynostosis.
abstract: In 1984, two young infants with unusual "clover-leaf" patterns of skull deformity were treated by posterior skull-releasing surgery that dramatically improved their overall skull shape, to the extent that further operative intervention was not required. This focused our attention on the posterior skull and its role in craniosynostosis. In cases of multi-suture craniosynostosis and craniofacial syndromes severely raised intracranial pressure is frequent, demanding early surgery. One of the problems identified with such surgery undertaken before 6 months of age is recurrent craniosynostosis needing later re-operation. This occurred in 15 (5%) of 275 patients treated between 1978 and 1994. Since 1986, in the presence of significant raised intracranial pressure it has been our policy to do an initial posterior skull release or decompression. This takes the pressure of the growing brain away from the orbits, allowing us to defer fronto-orbital advancement until the age of 12 months or later. Three patients managed in this way completely avoided anterior surgery, while in another 9 patients re-operation for recurrent anterior deformity has not been required. The exception to this policy has been the presence of severe exorbitism posing a threat to vision. Under these circumstances early fronto-orbital advancement is mandatory, and an additional posterior skull release may be helpful later. Debate continues especially on the management of unilateral lambdoid synostosis. The recent increase in positional posterior plagiocephaly. possibly related to supine nursing of newborns, has emphasised the need to differentiate between a fixed deformity, which might require surgical correction, and positional moulding of the occiput, which improves spontaneously. This paper reports our experience with 22 patients treated by posterior skull surgery, either alone or as an additional procedure, which we believe has a definitive role in the management of craniosynostosis.
