Radiation to the head and neck is commonly used in the treatment of cancers. A side effect in some patients is the development of pharyngeal and or esophageal strictures. Hypopharyngeal strictures can resemble edematous larynges. If mistakenly so identified, tracheal tubes placed through these structures are unlikely to result in tracheal intubation and more likely to cause obstruction, esophag...
Using ultramorphological and histochemical techniques, this study describes the structural and morphological patterns of Polistes versicolor (Olivier) hypopharyngeal glands, comparing them with patterns of other Hymenopteran groups. Besides, the presence of intra-specific variation was evidenced by morphometric analysis of the secretory cells in wasps with different ages. The studied species pr...
Although highly conformal dose distributions can be achieved by IMRT planning, this often requires a large number of segments or beams, resulting in increased treatment times. While flattening-filter-free beams offer a higher dose rate, even more segments may be required to create homogeneous target coverage. Therefore, it is worthwhile to systematically investigate the dependence of plan quali...
Abstract Objectives Salvage surgery for hypopharyngeal cancer remains a major challenge, and only few studies have been conducted. In this study, we review our 10 years of experience in treating patients with cancer. The main aim study is to analyze survival outcomes who underwent salvage compared those had complete remission or inoperable residual tumors. Methods Chart reviews were performed a...
