CPT® Code 69602

A revision mastoidectomy is a surgical procedure aimed at addressing complications related to the mastoid air cells, which are small, air-filled spaces located within the mastoid process of the temporal bone, situated behind the ear. This procedure is specifically indicated for patients who have experienced recurrent infections or other issues that necessitate the removal of infected or diseased tissue within the mastoid area. During the surgery, an incision is made behind the ear to access the mastoid bone, allowing the surgeon to inspect the remaining mastoid air cells and determine the extent of the necessary revision. The goal of the revision mastoidectomy is to effectively manage conditions such as recurrent cholesteatoma, which is an abnormal skin growth in the middle ear that can lead to further complications if not treated. The procedure can vary in its extent, resulting in either a modified radical mastoidectomy or a radical mastoidectomy, depending on the severity of the condition and the structures involved. In the case of a modified radical mastoidectomy, the procedure preserves critical structures such as the tympanic membrane and middle ear components while removing the infected air cells and parts of the external auditory canal to facilitate proper drainage and healing.
