Cranial base in newborns with XXXX : radiographic study.

@entity1 @entity542 @entity600 @entity2419 @entity3384
In a 1993 study, M  lsted and colleagues found an increased width of the @entity3384 compared with newborns with @entity2419 . As the @entity542 represents remnants of the early chondrocranium that later ossifies and incorporates in the cranial base, it is possible that an inborn alteration, such as a deviant growth of cartilage, or a delayed maturation in the early development of the cartilaginous cranial base, can affect not only the length and the width of the cranial base, but also the petrous portion of the temporal bone and the nasal septum, as these structures also have a cartilaginous origin. The purpose of the present study was to measure the cranial base width, including the width of the maxilla, and to measure the bilateral angulation of the petrous portion of the temporal bone and the sphenoid bone in 3-month-old @entity1 with complete clefts and in 3-month-old @entity1 with an incomplete @entity3384 , and to compare the two groups. Fifty-two @entity1 with complete clefts (CLP) without associated @entity600 comprised the test group. Forty-eight @entity1 with a minor, incomplete @entity3384 ( @entity3384 ) constituted the control group. The results of the comparison showed marked differences between the CLP and @entity3384 groups. In the CLP @entity1 , the cranial base width and the bilateral angulation of the sphenoid bone increased. An increased angulation was also seen between left and right sides of the pars petrosa. Furthermore, increased maxillary width was found.(ABSTRACT TRUNCATED AT 250 WORDS)
