Summary
This study created the first stapes prosthesis phylogenetic tree, revealing evolutionary pathways and aiding in the design of new prostheses for stapedectomy. The tree categorizes 105 prostheses into 4 main branches.
Area of Science:
- Otolaryngology
- Medical device evolution
- Surgical innovation
Background:
- Stapes prostheses are crucial for stapedectomy, a procedure to restore hearing.
- Understanding their evolutionary history can inform future device development.
Observation:
- A retrospective review of 105 stapes prostheses was conducted.
- The study involved literature review and personal interviews.
- A phylogenetic tree was constructed to map prosthesis evolution.
Findings:
- The stapes prosthesis phylogenetic tree includes 4 main branches, categorizing all commercial prostheses.
- The review identified historical trends, including atavistic designs and single-surgeon innovations.
- The tree provides a comprehensive overview of stapes prosthesis development.
Implications:
- The phylogenetic tree offers valuable historical perspective on stapedectomy procedures.
- Insights gained can guide the design of improved and novel stapes prostheses.
- This evolutionary mapping aids in understanding the trajectory of otologic surgical tools.

The Auditory Ossicles
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Anatomy of the Ear
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
