A Debate on Pharyngolaryngeal Histopathologic Examination of the Cadaver Suspected of Pressure on Vital Elements of Neck: Death Cause

\ud Pressure on the neck is one of the oldest and controversial types of death. However, the only hypoxia as the cause of speed death is not always correct. Many victims die immediately without classic symptoms of respiratory failure (Shirzad & Gharedaghi, 2007). Most of the deaths which occur in less than one to three minutes are falls in this category. Pressure on the neck leads to airway obstruction, neck veins obstruction, blocking the carotid arteries, and affect the nerves. A variety of causes is associated with fatal pressure on the neck, including strangulation by hand, strangulation with a ligature, and hanging. Hanging is the method used maximally in suicide as compared to other methods of suicide (Graham et al., 2000; Gould & Kramer, 2001). Including Iran, it is the most common method adopted for suicide in Asian countries (Morovatdar et al., 2013; Shojaei et al., 2014), especially adopted by men, older and especially illeterate people (Pridmore & Walter, 2013)
