background morphometric data of the frontal lobe are important for surgical planning of lesions in the frontal lobe and its surroundings. magnetic resonance imaging (mri) techniques provide suitable data for this purpose. objectives in our study, the morphometric data of mid-sagittal mri of the frontal lobe in certain age and gender groups of children have been presented. patients and methods i...

Abstract Introduction: Estimating the appropriate time for orthodontic treatment is a crucial factor. Given the earlier maturation of sinuses rather than maxillomandibular growth, finding the exact relationship between the growth of the jaws and frontal sinuses is considered to be a helpful element in Orthodontic treatment.

Background and Objectives: The frontal sinus is regarded as one of the human paranasal sinuses located in the frontal bone as a triangular-shaped cavity, which originates as separated space from the anterior ethmoid cells. Computed Tomography (CT) is a completely non-destructive technique that uses a high density of contrast to identify the air inside any bony sinus with soft tissue demarcated ...
