Mastoidectomy reconstruction of the posterior wall and obliteration (MAPRO) was found to be an effective approach for completely removing a choLesteatoma and preventing cholesteatoma recurrence. It is water-safe and provides an excellent basis for hearing restoration. The use of the original posterior bony canal for middle ear reconstruction was found to be beneficial. The authors advise an MRI study 18 months after surgery for cholesteatoma detection. 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.
