2023年8月4日 · Scaphocephaly (also known as dolichocephaly) is the most common form of craniosynostosis, where premature closure of the sagittal suture results in an impediment to the lateral growth of the skull while anteroposterior growth continues, producing a classic elongated, yet narrow, skull.

Premature closure of the sagittal, coronal and metopic sutures are associated with scapho-cephaly or dolichocephaly, brachycephaly and trigono-cephaly, respectively. Plagiocephaly develops when only one coronal or lambdoid suture is closed. Scaphocephaly is the most frequent form of simple craniosynostosis.

When a craniosynostosis is suspected, the first line imaging will be ultrasound or x-rays, depending on local expertise and preferences. Because of lack of radiation, ultrasound is the preferred method. In case of high clinical suspicion low dose 3D CT is preferred.

Fetal magnetic resonance imaging can facilitate the evaluation of the palate, micrognathia, cranial sutures, brain, and other fetal structures. Invasive prenatal diagnostic techniques are indicated to exclude chromosomal abnormalities. Molecular analysis for some syndromes is feasible if the family history is suggestive.

2003年4月9日 · Premature closure of the sagittal, coronal and metopic sutures are associated with scaphocephaly or dolichocephaly, brachycephaly and trigonocephaly, respectively. Plagiocephaly develops when only one coronal or lambdoid suture is closed.

2020年9月1日 · Although these 2 terms have been used interchangeably by many, dolichocephaly refers to an elongated head without associated biparietal narrowing and is caused by positioning. Dolichocephaly most commonly occurs in …

Premature closure of sagittal suture. The sagittal suture permits growth in the width of the skull; premature closure results in a cranium that is high, long, and narrow (dolichocephaly). The calvarium is elongated in the antero-posterior (A-P) direction.

2019年2月16日 · Craniosynostosis, the premature closure of cranial sutures, should be suspected in the presence of significant dolichocephaly or brachycephaly and may be associated with other anomalies or syndromes.

2019年11月8日 · Craniosynostosis, the premature closure of cranial sutures, should be suspected in the presence of significant dolichocephaly or brachycephaly and may be associated with other anomalies or syndromes.

Dolichocephaly is the term given to a similar head shape, with decreased CI, but less keel shape. It is less often associated with craniosynostosis; it may be commonly seen in the premature infant and is more frequently a normal variant.
