Maxillary sinus hypoplasia (MSH) is an uncommon abnormality of paranasal sinuses noted in clinical practice. Computed tomography (CT) scan helps in diagnosing the anomaly along with any anatomical variation that may be associated with it. MSH is usually associated with other anomalies like uncinate process hypoplasia. Three types of MSH have been described. Type 1 MSH shows mild maxillary sinus...

Purpose Previous reports have demonstrated diminished size of the hindfoot bones in patients with idiopathic clubfoot deformity. However, no study has quantified the percentage of hypoplasia as a function of early growth, during the brace phase of Ponseti treatment. Methods We measured the dimensions of ossified structures on radiographs in patients with unilateral Ponseti-treated clubfeet to...

Cartilage hair hypoplasia (CHH), is a rare cause of metaphyseal chondrodysplasia and short stature. Other featuresincluded hair abnormality, immunodeficiency, anemia, gastrointestinal disorders (Hirschsprung disease,celiac, …) and increased risk of cancer. The disease is an autosomal recessive disorder and previously has notbeen reported in Iran. We report a 9-year-old boy diagnosed as cartilag...

o bjectives: the aim of this study was to determine the cementum thickness in the first molars of patients with localized aggressive periodontitis (lap) compared to healthy individuals. materials and methods: this case-control study compared eight first molar teeth af-fected by lap with eight third molar teeth of healthy individuals. the teeth were dis- infected by immersion in 10% buffered for...

Glenoid hypoplasia is a relatively rare alteration that in most cases involves the pectoral girdle in a bilateral and symmetrical manner. In general, glenoid hypoplasia is associated with skeletal changes such as hypoplasia of the humeral head or changes in the morphology of the acromion and of the coracoid. We describe a rare case of unilateral glenoid hypoplasia without instability and not in...

Although it is well known that enamel hypoplasia commonly is observed in prematurely born, very low birthweight (VLBW) children, its pathogenesis is not understood clearly. One likely mechanism may be related to mineral deficiency, which may be diagnosed as radiological demineralization of the long bones. In this study, we compared the cortical area of the humerus as measured from neonatal radi...

Since its first description optic nerve hypoplasia has been identified with increasing frequency, and a range of associated problems have been described. The major neurological and endocrine associations are well established, but those factors that predispose to the development of optic nerve hypoplasia remain unclear. To understand the aetiology of these problems better, and to formulate a man...
