Suturotomy for Various Flaps in the Newborn and Infant
In the newborn and infant reflection of frontal, bifrontal, parietal, and other flaps with the use of the perforator and either Gigli saw or craniotome is unnecessary and dangerous, since the skull is composed entirely of membranous bone. The skull thickness measures less than 3 mm, and each bone rides freely over the brain, suspended and moored, as it were, from the membranous sutures. Individual bones are separated from one another by open suture lines, and ossification is at least a year from being complete. The bones offer no resistance to the pressure of a perforator or burr. (See Figures 4.1 to 4.6.)
