Sphenoid Bone*

The anterior clinoid process, the medial end of the lesser wing of the sphenoid bone, may be pneumatized by sphenoid sinus as part of normal development. The cases of sphenoid mucocele described in literature are sparse, especially located in anterior clinoid that is a bone structure seldom presenting pneumatization. Therefore generally showing no anatomic substrate justifying the development and the growth of a mucocele, have to be considered really exceptional. We present three cases of anterior clinoid process mucocele which were managed by a endoscopic transnasal transsphenoidal approach.

The morphology and location of the pterion was investigated in total of 149 Korean skulls (298 pteria). The most common form of the pterion was a sphenoparietal articulation in the incidence of 76.5%. The most common location of the pterion was in an area which covers 5 mm from the supraorbital horizontal line parallel to Frankfurt line and the incidence was 81.8%. The metric location of the pterion was on 36.9 +/-3.8 mm above the upper margin of the zygomatic arch and 26.8 +/-4.5 mm behind the posterior margin of the frontozygomatic suture. The average length of the pterion was 12.2 +/-4.4 mm. The most common form of the epipteric bone was a single bone which articulated with the frontal, parietal, temporal and sphenoid bone, and the incidence was 40.3%. The most common location of the epipteric bone was in an area which covers 5 mm from the supraorbital horizontal line parallel to Frankfurt line and the incidence was 45.2%. Morphological analysis of the pterion, when combined with some other non -metric and metric variants, may become useful physical anthropologic tools for the identification of the Korean skull.

We report a case of coincidental pituitary adenoma and sphenoid meningioma. Computed tomographic scan had shown a large intrasellar rim enhancing mass and another well-enhancing mass with reactive bony thickening on the medial sphenoidal ridge. Magnetic resonance image revealed a snow-man shaped, expansile intrasellar mass, with small supra-sellar component, and a small enplaque-type enhancing dural thickening on the right medial sphenoidal ridge. Histopathologically, the intrasellar mass was diagnosed as pituitary adenoma and the other mass as secretory meningioma. We present clinical, radiological, and histopathological findings and review the reported cases of coincidental pituitary adenoma and meningioma without irradiation or trauma.

Maffuci's syndrome is characterized by defects in cartilage bone formation (dyschondroplasia) with subcutaneous multiple vascular hemangiomas, and often with enchondromas. More than 120 cases of this syndrome, which was first described by Maffucci in 1881, has been reported. But intracranial tumors are rare complication of this syndrome. In this paper we describe the 6th case in the world report of Maffucci's syndrome complicated by an intracranial tumor, which was confirmed histologically as a chondroma, and review the literature with regard to this rare complication of Maffucci's syndrome.

This study was undertaken to investigate the midline having the least difference between the right and left structures among the lines that had been used in the study of the craniomaxillofacial asymmetry. The sample of this study consisted of twenty six Korean girls(average 18.9 years old) having normal facial appearance and occlusion. On the frontal cephalometric films of the sample, we divided the whole craniomaxillifacial area into four portions, i.e., cranial, upper facial, lower facial, and dental portion. So, we have found the midlines having the least difference in the whole craniomaxillofacial area itself, and in the each divided four portions, furtherly in the other portions from aimed portion. The findings were as follow: 1. In the whole craniomaxillofacial area, the connecting line between crista galli and anterior nasal spine and the perpendicular bisecting line between right and left foramen rotundums were suitable for the midline. 2. In the cranial portion, established all six lines were suitable for midlines. In the other portions, the perpendicular bisection line between both condylion, the line passing the contact point between right and left mandibular central insisiors among the perpendicular lines between right and left mandibular central incisial tips were suitable midlines for evaluating the asymmetry of cranial portion. 3. In the upper facial portion, the perpendicular bisecting line between right and left zygions was the most suitable midline. In the other portions, the line between the crista galli and the most superior point of the odontoid process, the perpendicular bisecting line between right and left gonions, the perpendicular bisecting line between right and left condylions, and perpendicular bisecting line between right and left foramens rotundum were suitable midlines for evaluating the asymmetry of the upper facial portion 4. In the dental portion, the perpendicular bisecting lines between right and left buccal cusps of both maxillary first molars and between right and left mandibular first molars were suitable midlines. In the other portions, the perpendicular bisecting line between right and left landmarks crossing the lesser wing of the sphenoid bone and orbit, the perpendicular bisecting line between right and left mental foramens, and the connecting line between crista galli and prosthion were suitable midlines for evaluating the asymmetry of dental portion. 5. In the lower facial portion, the perpendicular bisecting lines between right and left condylions and between right and left gonions were suitable midlines. In the other portions, the line between the crista galli and anterior nasal spine, the perpendicular bisecting line between right and left foramen rotundums, and the perpendicular bisecting lines between right and left buccal cusps of both mandibular first molars and between right and left maxillary first molars were suitable midlines for evaluating the asymmetry of the lower facial portion.

Fibrous dysplasia of bone is an uncommon condition of unknown etiology in which the bones become progressively thicker and lose their normal structure. The skull and the bones in other parts of the body are involed in a process characterized by small areas of bone destruction or massive sclerotic overgrowth. They appear denser, although actually are softer, and give a rather homogenous, smeary impression. There may be cyst like areas within the large, dense, homgenous-appearing amorphous bone. Although the skull may be the only area of involvement it is not uncommon to have similar but more cystic appearing lesions in many other bones. The authors report two cases of fibrous dysplasia involving frontal, orbital roof, ethmoid, zygoma and sphenoid bone in the left by which disfiguration of appearance of the face was resulted in association with exophthalmus.
