CPT® Code 69905

A labyrinthectomy is a surgical procedure that involves the removal of the inner ear structures, specifically the labyrinth, which is a complex system of canals and cavities located within the petrous portion of the temporal bone. The labyrinth is composed of two main layers: the bony labyrinth, which provides structural support, and the membranous labyrinth, which contains the sensory organs responsible for balance and hearing. This procedure is primarily indicated for patients suffering from Meniere's disease, a condition characterized by episodes of vertigo, tinnitus, and hearing loss. The labyrinthectomy is effective in alleviating the debilitating symptoms of Meniere's disease by excising the affected inner ear structures that disrupt balance. It is crucial to note that this procedure is only performed on patients who have little to no residual hearing in the affected ear, as the removal of the inner ear will result in complete deafness in that ear. The specific approach for this procedure, as denoted by CPT® Code 69905, is the transcanal approach, which involves accessing the inner ear through the ear canal, allowing for a minimally invasive surgical technique.
