Brachycephaly

Introduction Short head deformity is caused by premature ossification of bilateral coronal sutures. After the bilateral coronal sutures are closed, the anterior symmetry is flat, so it is also called flat head deformity or wide head deformity. About 14.3% of the patients have coronal suture ossification on both sides of the skull, resulting in anterior and posterior diameter development of the skull and compensatory transverse diameter widening. The cranial top is elevated, so the head is widened, the forehead wide flat cranial fossa is enlarged, the eyelid becomes shallow and the dysplasia is poor, and the eyeball is prominently like the "goldfish eye".

Cause

Due to congenital hypoplasia, the bone density of the coronal sutures on both sides of the child can be seen to increase the skull base to shorten the cranial anterior fossa, while the sphenoid winglets are lifted upwards and backwards, and the wing points are raised. The armpit deepens the eyelid volume to become smaller.

A few weeks after birth, the child can have obvious deformity. The upper part of the bone is high and the lower part of the upper part is flattened. Sometimes the upper part of the frontal part of the frontal part of the frontal part of the frontal part of the frontal part of the frontal The part is retracted, and the nasal bone is pulled to the back to cause the bridge of the nose to sink. The nasopharyngeal cavity becomes smaller, and sometimes the skull base and hard palate often have abnormal upper respiratory tract infections. The ossified coronal suture touches the beaded bone nodule.

Differential diagnosis

1. Long head deformity: One of the manifestations of cranial stenosis is a scaphoid deformity, also known as a long head deformity, which is caused by the early closure of the sagittal suture. It is the most common cranial malformation in craniosynostosis, accounting for about 40%. ~70%.

2, triangular head deformity: the forehead is closed, the forehead becomes smaller, and the back of the head is overgrown, called the triangular head deformity. Triangular head deformity is a facial symptom of pediatric craniofacial deformity syndrome.

3, oblique head deformity: oblique head deformity, also known as partial head deformity, is a unilateral coronal ossification caused by unilateral dysplasia of the frontal bone, accounting for about 4%. The bilateral growth of the skull was asymmetrical, and the frontal frontal bone was flattened and retracted. The lesion side affects the development of brain tissue, and the anterior iliac crest still exists, but it is biased to the healthy side. Premature closure of the epiphysis can be reached in the middle of the forehead. The asymmetry of the frontal bone affects the entire cranial sacral shape, the sagittal suture is biased to the disease side, and the frontal frontal bone and the parietal bone are excessively bulged. The ossification of the unilateral coronal suture can penetrate deep into the wing point and the skull base. Therefore, the oblique head deformity is almost always accompanied by facial asymmetry deformity, and it is aggravated with age. The distance between the eyes becomes smaller and the forehead becomes narrower. The auricle and the external auditory canal can also be asymmetrical, but not obvious, and the deformity of the ankle is more pronounced. Oblique head deformity combined with mental retardation, cleft palate, ocular fissure malformation, urinary system malformation and total forebrain malformation.
