Myringotomy and tympanostomy, in parallel with the general distinction between an -otomy (cutting) and an -ostomy (creating a stoma with some degree of permanence or semipermanence). In this distinction, only a tympanostomy involves tympanostomy tubes and creates a semipermanent stoma. This distinction in usage is not always made. The word "tympanocentesis" specifies that centesis (aspiration for sampling) is being done. Etymologically, "myringotomy" ("myringo-", from Latin "myringa" "eardrum", + "-tomy") and "tympanotomy" ("tympano-" + "-tomy") both mean "eardrum cutting", and "tympanostomy" ("tympano-" + "-stomy" means "making an eardrum stoma". In 1649, Jean Riolan the Younger accidentally pierced a patient's ear drum while
Body part as an object than IO pantomimes (despite the prevailing conception that they are simpler), and that BPO involves the right hemisphere as well as the left hemisphere. These results could be extended as an explanation of why apraxic brain damage - usually found in left-hemisphere - leads to BPO production. This may be an indication that apraxic’s utilize their right-hemisphere in lieu of their left-hemisphere damage, and therefore produce more BPO pantomimes. Concepts leading to the exploration and discovery of body part as object pantomimes first began in the late 19th century. Problems in the ability to comprehend or communicate with symbols, asymbolia,
