The authors report, concerning 115 cas of scaphocephaly, the clinical (spheno., lepto., bathmo., clino., the kinds without dolichocephaly) radiological characteristics (temporal curve without dolichocephaly), orbito-sphenoidal obliquity regressing after treatment). They discuss the accepted ideas of the merely morphological problems of this type of craniostenosis, about their clinical and X-ray findings of encephalic disorder. The therapeutic methods are stated, so are the complications met during the surgical treatment. They suggest the craniectomy, taking away the sagittal suture associated with the linear coagulation of the dura mater. To the median sagittal craniectomy, one can add retrocoronal, pre lambdoid or metopic craniectomies according to the type of scaphocephaly. This treatment is simple, efficient and not very dangerous during the first year.
