Objective: The present study was undertaken to compare the pharyngeal dimensions in Angle’s Class I normal and Angle’s Class II division 1 samples, and to correlate it with the dentoskeletal parameters in both the groups. Materials and methods: The sample consists of 92 pretreatment lateral cephalogram, which were categorized into two groups, Group A and Group B, that they should present Angle’...

The neoplasms of the Parpharyngeal Space (PPS) are rare 0.5%-1% all head and neck tumors [1]. PPS is an inverted cone-shaped region that extends from skull base to hyoid bone. A complex structure called tensor-vascular-styloid fascia, divides into prestyloid poststyloid compartments. can be involved by four different types neoplastic lesions: Primary (benign or malignant), metastatic lymph node...

Endothelin 1 (Edn1), a secreted peptide expressed ventrally in the primordia of the zebrafish pharyngeal arches, is required for correct patterning of pharyngeal cartilage development. We have studied mutants and morpholino-injected larvae to examine the role of the Edn1 signal in patterning anterior pharyngeal arch bone development during the first week after fertilization. We observe a remark...
