The maxillary sinus appeared first among the sinuses of the skull at 92 days of prenatal stage. The early formation of frontal sinus was observed at 157 days in the cranial most part of the frontal bone while the early formation of palatine sinus was observed at 170 days. A total of five fontanelles were observed in prenatal skulls of buffalo. The largest and unpaired fontanelle was anterior fontanelle. The mastoid and sphenoidal fontanelle were paired. The ossification of anterior fontanelle was first observed at 164 days. All the fontanelles were ossified completely prenatally.

This case report describes a patient who had a foreign body in transverse sinus. A 35-year-old Korean-Chinese man visited the emergency room with lacerated wound in left eyelid and a foreign body which was stumbled upon in the skull. On examination, there was right side hemianopsia in his left eye. He did not complain any headache or show any abnormal neurological signs, but there was a foreign body at left transverse sinus in computed tomography which was taken at another hospital. There was no intracranial abnormality except the foreign body in computed tomography. Because of the financial problem, additional evaluations were not possible. We herein report a strange case in which the pathway of a foreign body to locate in transverse sinus was ambiguous, and suggest that the foreign body located in transverse sinus might have been the penetrated along the anterior fontanelle and passed through the superior sagittal sinus.

OBJECTIVETo study the development of anterior fontanel(AF) in children less than 2 years of age.

METHODThe size of AF of the children under 2 years of age was measured. The criteria were: (1) All the children were singletons and term (37 weeks ≤ gestational age ≤ 40 weeks) at birth, birth weight > 2500 g. (3) Those with intracranial diseases (included trauma and asphyxia) and scalp hematoma were ruled out. (3) Healthy children (without intracranial disease, growth retardation, congenital syndrome or bone metabolic diseases such as rickets).

RESULT(1) The mean value of AF in neonates was 1.5 (0.3 - 2.5) cm, and the average of the AF at 1 month after birth was 2.2 cm, which was the largest one. The size of AF was 1.0 (0.3 - 2.0) cm at age 12 months, and 0.5 (0.3 - 0.7) cm at 24 months. (2) The percentage for the closure of the AF was 3% at 6 months, 26.5% at 12 months, and 93.0% at 24 months. (3) There were no gender differences in the size of the AF (P > 0.05). And the size of AF was not correlated with the development levels of weight, length, and head circumference (P > 0.05).

CONCLUSION(1) The size of AF at 1 month was maximum (2.2 cm), and then decreased by years. The AF was almost closed (93%) at 24 months. (2) There were no gender differences in anterior fontanel (P > 0.05). The size of AF was not correlated with the growth of weight, length, and head circumferences (P > 0.05). (3) The fontanel dimensions should be represented by oblique diameters of the fontanel in clinical pediatrics. (4) The AF closure time needs to be further evaluated in normal children.

PURPOSE: Neonatal cranial sonongraphy performed through the mastoid fontanelle is more useful to evaluate the peripheral structures at the convexity of the cerebral hemispheres and brainstem rather than that performed through the anterior fontanelle. The purpose of this study is to demonstrate the anatomy of the extracerebral CSF space and brainstem and to suggest appropriate scan planes for performing neonatal cranial sonography through the mastoid fontanelle using MRI and multiplanar reconstruction programs. MATERIALS AND METHODS: A neonate with normal features on ultrasonography and good image quality on MRI, including the 3D-SPGR axial scans, was selected. We made the reconstructed MR images corresponding to the sonongraphic planes and the anatomic models of the neonatal cranial sonographic images by using axial MRI as the standard reference on the same screen. We demonstrated the sonographic images at the levels of the body of the caudate nucleus and lentiform nucleus, the head of the caudate nucleus and thalamus, the third ventricle and midbrain, and the midbrain and cerebellar vermis on the oblique axial scans. Four oblique coronal images at the levels of the periventricular white matter, basal ganglia, thalamus and tentorium were also obtained. RESULTS: We illustrated the anatomic atlas with including four oblique axial scans and four oblique coronal scans that corresponded to the neonatal cranial sonographic images through the mastoid fontanelle. CONCLUSION: We objectively analyzed the anatomy of the extracerebral CSF space and brainstem by using MRI and multiplanar reconstruction programs and we provided the standardized sonographic scan planes through the mastoid fontanelle. This study will be very helpful for evaluating the abnormalities of the peripheral structures at the convexity of the cerebral hemispheres and brainstem.

PURPOSE: Neonatal cranial sonongraphy through the posterior fontanelle is more useful than through the anterior approach for the evaluation of posterior brain structures. The aims of this study were to determine the appropriate neonatal cranial sonography scan planes through the posterior fontanelle, and to objectively evaluate the anatomy of neonatal cranial sonographic images. MATERIALS AND METHODS: Neonates who underwent cranial sonography and MRI including 3D-SPGR axial scans and showed normal features on both modalities were enrolled. We reconstructed MR images corresponding to sonongraphic planes, then constructed anatomic models of the neonatal cranial sonographic images using axial MRI as the standard reference on the same screen. RESULTS: We successfully created anatomic atlas that represents 8 oblique coronal and 4 oblique sagittal scans and planes that corresponded to the neonatal cranial sonographic images through the posterior fontanelle. CONCLUSION: The objective manner of this anatomic research provided standardized sonographic scan planes and created anatomic model through the posterior fontanelle. Cranial sonographic models through the posterior fontanelle using MRI and multi-planar reconstruction program will be helpful in the evaluation of sonographic anatomy and detection of abnormalities in the basal ganglia, thalamus and posterior part of the brain.

PURPOSE: It is critical that the exact gestational age of a newborn baby, especially premature baby, be determined to evaluate the status of a disease and its management and to estimate the prognosis of a patient. This study aimed to investigate an easy and accurate method to estimate gestational age on cranial ultrasound, requiring minimal additional time and equipment. METHODS: A high-resolution coronal sonographic image was obtained via the anterior fontanel with a 5-12 Mhz linear probe after the usual cranial sonographic examination. We measured the depth of cerebral hemisphere, thickness of corpus callosum, and depth of cingulate sulcus and obtained the correlations between these factors and gestational age. RESULTS: Depth of cingulate sulcus had the highest correlation coefficiency with gestational age (r=0.878, P=0.000). All the cases, except for 2 cases, had a gestational age of more than 37 weeks, when the depths of cingulate sulcus were more than 0.55 cm, and had a gestational age less than 34 weeks, when the depths of cingulate sulcus were less than 0.35 cm. CONCLUSION: Measurement of the depth of cingulate sulcus was a simple and accurate method to estimate the gestational age on cranial ultrasound. The gestational age is more than 37 weeks, when the depth of cingulate sulcus is more than 0.55 cm, and is less than 34 weeks, when the depth of cingulate sulcus is less than 0.35 cm.

PURPOSE: Cleidocranial dysostosis is a rare hereditary disorder affecting bones that develop by intramembranous formation. The typical features include excessive growth of transverse diameter of the skull, hypoplastic clavicles, low height and characteristic facial features. METHODS: A 28-year-old female patient visited by frontal area depression. The diagnosis was performed by computed tomographic study and radiographic imaging. The patient had widely opened anterior fontanelle, partial fused metopic suture, multiple wormian bone and supernumenary impacted teeth. Under the coronal incision, we exposed depressed frontal area and corrected with Medpor block carving. RESULTS: Postoperatively frontoparietal skull was aestheticlly improved and satisfied the patient. CONCLUSION: Authors report a case of cleiodocranial dysostosis who underwent correction of abnormal skull shape by Medpor(R) insertion.

Robinow syndrome is a rare inherited disorder initially reported by Robinow et al. in 1969 as a new dwarfing syndrome. It is characterized by the presence of fetal face, forearm shortening, genital hypoplasia, and hemivertebrae. The autosomal recessive form of Robinow syndrome shows a more severe clinical phenotype which is expressed by the mutation of homozygous ROR2(Receptor tyrosine kinase like Orphans) gene, mapped to the chromosome 9q22, a region that overlaps the locus for autosomal dominant inherited brachydactyly type B(BDB). ROR2 encodes the receptor tyrosine kinase, which is important for the development of mesomelic long bones. We experienced a boy diagnosed as a Robinow syndrome with fetal face(frontal bossing, hypertelorism, small up-turned nose, triangular mouth with down turned angles, micrognathia), large anterior fontanelle, cranium bifidum, mesomelic shortening, cryptorchidism. We present this case with a brief review of related literature.
