Ossiculoplasty Failure with Ceramic Ossicular Replacement Prosthesis

ORL, 2010
The stability of ceramic ossicular replacement prosthesis (CORP) in the middle ear was evaluated in 162 ears that had been followed for more than 18 months. The CORP extruded from 8 ears (4.9%) and was dislocated in 6 ears (3.7%). These failures were considered to be due mainly to postoperative tubal dysfunction and disease recurrence.

[Application of combined ossicular replacement prosthesis and total ossicular replacement prosthesis of type Ⅲ tympanoplasty].

Lin chuang er bi yan hou tou jing wai ke za zhi = Journal of clinical otorhinolaryngology head and neck surgery, 2022
Objective:This study investigated the application of combined ossicular replacement prosthesis（The Kurz Omega Connector+TORP） in type Ⅲ tympanoplasty, and compared the surgical effect with traditional TORP. Methods:Twenty patients with unilateral chronic suppurative otitis media diagnosed in the Department of Otorhinolaryngology, Sun Yat-sen Memorial ...

Magnetic ossicular replacement prosthesis

The Journal of the Acoustical Society of America, 1989
An ossicular replacement prosthesis containing a magnet in the head of the prosthesis so that when used with a magnetic induction hearing aid having a coil producing a magnetic field, the hearing losses resulting from insertion of the prosthesis and any other remaining hearing losses can be corrected without the difficulties associated with ...

Optimizing Ossicular Prosthesis Design and Placement

2018
Middle ear hearing reconstruction is unpredictable. Difficulties arise because of host factors, such as ventilation or scarring, surgical technique factors, such as prosthesis placement and stabilization, and design and mechanical factors influencing the properties of the prosthesis.

Hearing Outcomes With a Novel Total Ossicular Replacement Prosthesis

Otology & Neurotology, 2020
Introduction: A total ossicular replacement prosthesis (TORP) is used to reconstruct the ossicular chain in the absence of the stapes suprastructure. The Wildcat prosthesis is a novel TORP that eliminates the need for a separate footplate shoe prosthesis and aims to improve ease-of-use and stability.

Partially implantable vibrating ossicular prosthesis

Proceedings of International Solid State Sensors and Actuators Conference (Transducers '97), 2002
A partially implantable hearing prosthesis for sensorineural hearing loss patients has been developed using a novel electromagnetic actuator. The system is designed to couple acoustic frequency, vibrational energy into the ossicular structure of the middle ear.

The vibrating ossicular prosthesis in children and adolescents: a retrospective study

European Archives of Oto-Rhino-Laryngology, 2019
The primary objective of the retrospective study was to collect speech intelligibility data on children and adolescents implanted with the vibrating ossicular prosthesis (VORP) 503.This was a retrospective, multicentre study on 55 children and adolescents from 6 German clinics aged between 5 and 17 years suffering from mixed or conductive hearing loss ...

Ossicular reconstruction: Incus versus universal titanium prosthesis

Auris Nasus Larynx, 2009
The main purpose of this study is to compare audiological outcomes of incus reconstruction, Xomed Medtronic universal titanium partial ossicular replacement prosthesis (PORP) and total ossicular replacement prosthesis (TORP). We also compared results based on surgical technique, history of previous surgery, form of the prosthesis head, pathology and ...

A Self-Adjusting Ossicular Prosthesis Containing Polyurethane Sponge

Otology & Neurotology, 2010
Middle ear ossicular replacement prostheses whose length can adjust in vivo to changes in middle ear dimensions following insertion may have acoustic advantages.Optimal tension is an important factor in the acoustic performance of incus-stapes replacement prostheses.

Plastipore^TM total ossicular replacement prosthesis

The Laryngoscope, 1976
AbstractIn those ears in which the incus and/or malleus are missing or not suitable, a columella made of high density polyethylene sponge has proven to be very effective. Tissue readily grows into the large pores of this material so that it is well tolerated in the body.
