Abstract:

Otosclerosis is the most common cause of progressive hearing loss of a conductive type in adults. Stapes mobilization effected by the direct method was revived in 1953. Recent procedures involve fenestration of the footplate, the use of a vein graft, and reconstruction of the stapes with tantalum or stainless steel wire or a polyethylene prosthesis. Fenestration of the horizontal semicircular canal is ordinarily considered permanently disqualifying for flying duties and a waiver can be granted only by the Surgeon General, U. S. Air Force. An Air Force policy has not been formulated with regard to fenestration of the footplate of the stapes. Aviation medicine principles should be considered in the choice of a surgical procedure for otosclerosis performed on an aircrew member. Mobilization of the stapes achieved conservatively by manipulation of the head of the stapes or occasionally by chisels is recommended and has been demonstrated not to have adversely affected the performance of flying duties by aircrewmen. Until it has been definitely determined that the middle ear can tolerate fenestration or removal of the footplate, addition of grafts and prostheses, without compromising the integrity of the inner ear while being subjected to the inevitable, repeated bouts of severe atmospheric pressure changes encountered in military aircraft, it would seem wise to refrain from using these procedures on flying personnel.
