Disorders of head shape and size

The oval shape of the newborn’s skull, resulting from the molding needed during passage through the tight birth canal, usually returns to normal after a short period of time. This is followed by rapid expansion of the skull due to its inherent plasticity. Nevertheless, significant distortions can occur as a result of change in the intracranial volume or the presence of constrictive or restrictive forces affecting the infant’s head. These distortions may be mild and reversible deformations or evolve into cranial malformations which are rapidly progressive and irreversible [1-6].
