CPT® Code 69320

The procedure described by CPT® Code 69320 involves the surgical reconstruction of the external auditory canal in patients diagnosed with congenital atresia, a condition characterized by the absence of the external ear canal, also known as aural atresia. This condition can occur in one ear (unilateral) or both ears (bilateral), leading to significant hearing impairment and potential complications related to ear infections and other auditory issues. During the procedure, the surgeon makes an incision in the skin at the site where the external auditory canal is to be formed. The surgical approach requires careful dissection and drilling of the overlying bone to reach the level of the ossicles, which are the small bones in the middle ear that play a crucial role in hearing. To reconstruct the canal, a small fascial graft is harvested and placed over the ossicles to serve as a foundation for the eardrum. Additionally, skin grafts are obtained and applied over the exposed bone within the newly created canal, ensuring proper healing and functionality of the reconstructed auditory pathway. This intricate procedure aims to restore hearing and improve the quality of life for individuals affected by this congenital condition.
