Tympanoplasty with mastoidectomy (including canalplasty, middle ear surgery, tympanic membrane repair); without ossicular chain reconstruction

A tympanoplasty with mastoidectomy is a surgical procedure that involves the repair of the tympanic membrane (eardrum) and the removal of infected or diseased tissue from the mastoid bone, which is located behind the ear. This procedure may also include canalplasty, which is the widening of the ear canal, and middle ear surgery to address various conditions affecting the ear. Tympanoplasties are categorized based on the extent of the repair needed; they can involve only the tympanic membrane or may also require the repair of the ossicular chain, which consists of small bones in the middle ear. In the case of CPT® Code 69641, the procedure is performed without any reconstruction of the ossicular chain. The surgical approach typically begins with an incision made behind the ear to expose the mastoid bone, allowing the surgeon to inspect the mastoid air cells and determine the necessary extent of the procedure. A simple mastoidectomy is performed, which involves the removal of purulent matter, debris, and infected tissue from the mastoid area. The tympanic membrane is then repaired, which may involve techniques such as rimming the edges of a perforation to promote healing or using a graft for larger holes. The procedure may also include the placement of absorbable materials to support the graft and ensure proper healing. Overall, this surgical intervention aims to restore hearing and prevent further complications related to ear infections and structural damage.
