Abstract
The cranial malformations, despite their rarity, have a great reflection on the social and mental development of child, in addition to the problems in visual and dental development.
• The present study discusses the physiopathology & therapy of these malformations, together with the study of the movements of the bones of skull base, their effects on the occurrence of these malformations, & their use in differentiation between the organic and functional or positional forms of plagiocaphaly. This study has also involved the effect of removal of parts of the skull base bones, in helping the normal growth of the brain and in decreasing these deformations.
• The present study was conducted upon 30 patients diagnosed by clinical and radiological methods using 3D CT scanning, which have also been used to study the cranial base deformations.
• The pre-and post-operative photographs were used for the evaluation.
• A hypothesis has been postulated to explain the movements of the bones of skull base and their effect on producing the clinical picture.
• An angle of curvature of the petrous pyramid has been observed, with a great increase of this angle in cases of functional plagiocephely which does not respond to the conservative treatment and the surgical treatment was practiced in these cases.
• The results of the present study were compared with the results of similar studies in the literature and showed an improvement of the heads together with improvement of the facial deformation in the late follow up.
• 2 cases died during this study, one in the immediate post-operative period due to anesthetic problems, and another 2 weeks after the operation from acute bronchospasm.
• Some post-operative complications have occurred such as, delayed ossification which have been corrected by the use of hydroxy apatite cement and wound dehiscence in some cases of oxycephely due to decrease in the bone growth and skin elasticity, as these cases are usually discovered at a later age.
• This study has shown the importance of surgical correction of the cranial malformation not only for esthetic purposes but also for the functional and mental development of the affected children
