KTP laser fine fenestra stapedotomy with vein graft interposition in the surgical management of otosclerosis.

Otosclerosis is an hereditary disease of bone derived from the embryonic otic capsule. The exact aetiopathogenesis remains unclear. It can be associated with significant disability due to hearing impairment. Medical and surgical treatments, with varying degrees of effectiveness and complication rates, are available. The surgical method for the correction of the conductive hearing loss associated with otosclerosis continues to undergo technical refinement with the aim of improving results and minimising complications. The surgical technique of fine fenestra stapedotomy is well established. Here, we describe a new modification of this technique involving the use of a KTP laser. Based on the retrospective review of the results and complication rates of over 200 consecutive cases, we would like to recommend the technique of KTP laser fine fenestra stapedotomy in the surgical management of otosclerosis.
