Tympanoplasty with antrotomy or mastoidotomy (including canalplasty, atticotomy, middle ear surgery, and/or tympanic membrane repair); without ossicular chain reconstruction

A tympanoplasty with antrotomy or mastoidotomy is a surgical procedure aimed at repairing the tympanic membrane (eardrum) and addressing issues within the middle ear. This procedure is particularly relevant for patients experiencing chronic ear infections, perforated eardrums, or other middle ear pathologies. The term 'tympanoplasty' refers specifically to the reconstruction of the tympanic membrane, while 'antrotomy' and 'mastoidotomy' involve creating an opening in the mastoid bone or the antrum, which is a cavity within the temporal bone, to facilitate drainage and access to the middle ear structures. The procedure may also include additional interventions such as canalplasty, which enlarges the ear canal, and atticotomy, which involves accessing the attic of the middle ear. Importantly, CPT® Code 69635 specifies that this procedure is performed without ossicular chain reconstruction, meaning that the small bones of the middle ear (ossicles) are not being repaired or replaced during this surgery. The approach can be through the ear canal or via a post-auricular incision, depending on the specific clinical scenario. The overall goal of this procedure is to restore hearing and prevent further complications by addressing the underlying anatomical issues within the ear.
