The suprahyoid neck extends from the hyoid bone inferiorly to skull base, excluding orbit, sinonasal and oral cavity. is anatomically complex but can be organized into different spaces based on fascial planes. Multiple systems with slightly namings are adapted. As a consensus, 5 principal 2 posterior midline recognized. Each space contains unique contents which subject predictable set of diseas...

Near total laryngectomy can be safely combined with partial or subtotal pharyngectomies when the disease is lateralized rendering the interarytenoid joint and the contralateral cricoarytenoid joint free of tumor. A case of post radiotherapy recurrent carcinoma of the posterior pharyngeal wall which could be salvaged by a circumferential pharyngectomy combined with a near total laryngectomy is r...

malignancy and tumor in ent are less common but more important, also they have not any certain sign until they progress thus it will be so important that we consider some abnormal common signs when we are examine patients until do not miss them, this study was conducted to establish the various clinical modes of presentation of pharyngeal neoplasm and their correlation with final histopathologi...

Low copy number plasmids in bacteria require segregation for stable inheritance through cell division. This is often achieved by a parABC locus, comprising an ATPase ParA, DNA-binding protein ParB and a parC region, encoding ParB-binding sites. These minimal components space plasmids equally over the nucleoid, yet the underlying mechanism is not understood. Here we investigate a model where Par...

OBJECTIVE Adenotonsillectomy is recognized as an effective therapy for snoring and sleep disorders in children. It is important to understand whether adenotonsillectomy significantly increases the volume of the pharyngeal space. The goal of this study was to evaluate the change in oropharyngeal volume after adenotonsillectomy and the correlation of this change with the objective volume of the t...
