Cholesteatoma - Canal Cases

1) View of the eardrum. Scarring of the eardrum is seen however there is no retraction or severe disease affecting the drum.
2) A large defect is visualized in the ear canal (white arrow). A large section of bone is missing in the ear canal. Skin can insinuate itself and create such a large defect and over time enlarge and trap debris within it. The eardrum is seen in the distance (black arrow).
3) A view of the large hole in the ear canal bone from behind, through the mastoid.
4) Once all the skin elements have been removed, the defect is clearly visualized (black arrow). Again, the eardrum is seen (white arrow).
5) A cartilage graft is harvested and utilized to reconstruct the ear canal bone and repair the defect (black arrow). The defect of the ear canal is “plugged” with the cartilage graft, eliminating the hole and preventing skin from growing into the bone.
6) A view of the cartilage graft from behind the ear canal-- from the mastoid cavity.
