| radical mastectomy, modified | Breast cancer treatment involving removal of the breast, lymph nodes (the glands ) in the armpit and associated skin and subcutaneous tissue. It differs from total radical mastectomy in that the pectoral (chest) muscles are preserved. (12 Dec 1998) |
| radical mastectomy, total | Breast cancer treatment involving removal of the breast, the pectoral (chest) muscles, lymph nodes (the glands ) in the armpit and associated skin and subcutaneous tissue. (12 Dec 1998) |
| radical mastoidectomy | An operation to exteriorise and join the mastoid air cells, the middle ear space, and the external meatus, often for extensive cholesteatoma. Synonym: tympanomeatomastoidectomy. (05 Mar 2000) |
