Right transcanal stapedotomy for a congenital oval window dysplasia and malformed stapes superstructure which is not connected to the bony stapes footpate in a 10 year old child. Teunissen-Cremers Class IV malformation. The footplate is fixed and really thick. The stapedotomy is performed using a combination of a hand-held Diode laser (NeoV) and a diameter diamond dust burr.
