what is the main difference between the treatment we discussed versus stapedotomy?
In the former the Stapes is replaced by artificial prosthesis whereas in the latter an artificial prosthesis is inserted by making a small hole in the base of the stapes
Clinical relevance
Two common treatments are stapedectomy, the surgical removal of the stapes and replacement with an artificial prosthesis, and stapedotomy, the creation of a small hole in the base of the stapes followed by the insertion of an artificial prosthesis into that hole. 
what are the 3 smallest bones in the human body Strapes is one of them what is the size of this above bone? Roughly 3 x 2.5mm which part of the body is this located? Middle ear of humans besides the human, is this bony structure present in other living species in the animal kingdom? It is one of three ossicles in mammals, in non-mammalian four-legged animals its homologous form is called the columella what are the functions this bony structure serves? It transmits sound vibrations from the incus to the oval window, a membrane-covered opening to the inner ear. are there any variations of this bony structure? It appears to be relatively constant in size in different ethnic groups can this bony structure get affected or impaired? Yes, its impairment causes conductive hearing loss is there any remedy to solve this? Two common treatments are stapedectomy and stapedotomy how is the first treatment that you mentioned - carried out? It is the surgical removal of the stapes and replacement with an artificial prosthesis what are some of the complications involved? Causes fibrosis-related damage to the base of the bone, or obliterative otosclerosis, resulting in obliteration of the base. what does the term otosclerosis mean? A condition where one or more foci of irregularly laid spongy bone replace part of normally dense enchondral layer of bony otic capsule in the bony labyrinth.
Comparisons have shown stapedotomy to yield either as good or better results than stapedectomy  and to be less prone to complications. The creation of a small hole in the base of the stapes followed by the insertion of an artificial prosthesis into that hole The stapedotomy method is not applicable in those relatively rare cases that involve scleroris of the entire ossicular chain and it is preferred to stapedectomy in the absence of predictable complications.

Stapedectomy vs. stapedotomy Clinical relevance Stapedectomy vs. stapedotomy
Comparisons have shown stapedotomy to yield either as good or better results than stapedectomy (measured by hearing improvement and reduction in the air-bone hearing gap, and especially at higher sound frequencies), and to be less prone to complications. In particular, stapedotomy procedure greatly reduces the chance of a perilymph fistula (leakage of cochlear fluid).  stapedotomy, the creation of a small hole in the base of the stapes followed by the insertion of an artificial prosthesis into that hole.  The stapedotomy method is not applicable in those relatively rare cases that involve scleroris of the entire ossicular chain.

Because it is a simpler and safer procedure, stapedotomy is normally preferred to stapedectomy in the absence of predictable complications.

Stapes [SEP] Clinical relevance
Otosclerosis is a congenital or spontaneous-onset disease characterized by abnormal bone remodeling in the inner ear. Often this causes the stapes to adhere to the oval window, which impedes its ability to conduct sound, and is a cause of conductive hearing loss. Clinical otosclerosis is found in about 1% of people, although it is more common in forms that do not cause noticeable hearing loss. Otosclerosis is more likely in young age groups, and females. Two common treatments are stapedectomy, the surgical removal of the stapes and replacement with an artificial prosthesis, and stapedotomy, the creation of a small hole in the base of the stapes followed by the insertion of an artificial prosthesis into that hole.
