Simultaneous assessment of intracranial pressure by anterior fontanelle palpation and direct measurement from a cerebrospinal fluid cannula showed that mean pressure was significantly different between 'soft' (5.4 mm Hg) and 'tense' (14.0 mm Hg) fontanelles, but with considerable overlap. Normal fontanelle tone was often confirmed, whereas clinical assessment of raised intracranial pressure was unreliable.
