Summary
This summary is machine-generated.Partial ossicular replacement prostheses (PORP) showed better hearing outcomes than total ossicular replacement prostheses (TORP) in endoscopic ossicular chain reconstruction. The stapes superstructure positively impacts reconstruction success.
Area Of Science
- Otolaryngology
- Surgical Innovation
- Audiology
Background
- Ossicular chain reconstruction outcomes vary, particularly concerning the stapes superstructure.
- Chronic suppurative otitis media necessitates effective surgical repair strategies.
Purpose Of The Study
- To compare hearing outcomes of partial ossicular replacement prosthesis (PORP) versus total ossicular replacement prosthesis (TORP) in endoscopic ossicular chain reconstruction.
- To evaluate the influence of the stapes superstructure on surgical success.
Main Methods
- Retrospective analysis of 111 patients with chronic suppurative otitis media undergoing ossicular chain reconstruction.
- Patients were divided into PORP and TORP groups, with further subgroups based on malleus handle presence.
- Pre- and postoperative audiometric results were analyzed.
Main Results
- PORP demonstrated significantly higher improvements in air conduction thresholds and air-bone gap compared to TORP.
- Success rates for reconstruction were significantly better with PORP in both malleus handle subgroups (PORP-a vs. TORP-a, PORP-b vs. TORP-b).
Conclusions
- Partial ossicular replacement prostheses yield superior hearing outcomes in endoscopic ossicular chain reconstruction compared to total ossicular replacement prostheses.
- The presence and integrity of the stapes superstructure are crucial for successful postoperative hearing results.

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...
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...
