Biomedical engineering (BME) or medical engineering is that the application of engineering principles and style concepts to medicine and biology for healthcare purposes (e.g. diagnostic or therapeutic). This field seeks to shut the gap between engineering and medicine, combining the planning and problem solving skills of engineering with medical biological sciences to advance health care treatment, including diagnosis, monitoring, and therapy.[1][2] Also included under the scope of a biomedical engineer is that the management of current medical equipment within hospitals while adhering to relevant industry standards. This involves making equipment recommendations, procurement, routine testing and preventive maintenance, a job also referred to as a Biomedical Equipment Technician (BMET) or as clinical engineering. Before the mid-19th century, mastoidectomy was performed only sporadically and in most cases as a desperate try and save the lives of individuals tormented by complications of infectious otitis. The drainage of acute abscesses became a typical procedure at the start of the 20th century, within the pre-antibiotic era. the primary documented section to empty an infected ear was described by the French physician Ambroise Paré within the 16th century. The credit for performing the primary mastoidectomy for the removal of purulent secretions visited Jean-Louis Petit. Mastoidectomies were normally performed to treat infections. However, mastoidectomies were also dole out for other purposes, particularly for the treatment of deafness and tinnitus, during various periods. Sir Charles Ballance credited Johannes Riolanus with recommending mastoidectomy for the treatment of tinnitus. William Wilde began the time of contemporary mastoidectomy together with his introduction of the eponymous retroauricular incision.
