About Fluoroplastic Offset Partial Prosthesis ( PORP )

In what cases and at what time is middle ear surgery indicated?

Complete deafness is rare in microtia because the inner ear, or neurosensory apparatus, is normal. Children have normal speech and adapt well without middle ear surgery. Middle ear surgery is generally reserved for bilateral microtia patients and is done after auricular reconstruction. In selected cases middle ear reconstruction can be performed in patients with unilateral microtia but should be planned following completion of the external reconstruction to avoid further complicating these procedures.

Anatomical Precision and Customizability

This fluoroplastic PORP is engineered with an offset shape, enabling optimal anatomical conformity within the middle ear. Its trimmable design allows ENT surgeons to accurately adapt the prosthesis during implantation, ensuring a comfortable and effective fit for diverse patient anatomies, thereby enhancing surgical outcomes.

Superior Material and Safety Standards

Constructed from medical-grade PTFE, the PORP demonstrates excellent biocompatibility, high tissue tolerance, and resistance to corrosion. Gamma or EtO sterilization and latex-free composition minimize risk of infection and allergic response, while individual packaging maintains sterility until the time of use.

Optimal Performance and Compatibility

The prosthesis supports real-time adjustments during surgery and is non-magnetic, making it MRI safe. Its versatile sizing accommodates a range of patient needs. Designed for ease of use and manual placement, the device aids in reliable restoration of auditory function, benefiting both patients and surgeons.

FAQ's of Fluoroplastic Offset Partial Prosthesis ( PORP ):

Q: What is the primary use of the Fluoroplastic Offset Partial Prosthesis (PORP)?

A: The main function of the PORP is to reconstruct the ossicular chain in the middle ear, restoring the sound conduction pathway in patients undergoing partial ossicular replacement procedures during ear surgery.

Q: How do surgeons ensure the PORP fits the patient's anatomy?

A: The PORP features an offset, trimmable design, allowing surgeons to shape the prosthesis intraoperatively for the best anatomical match. This ensures precise placement between the tympanic membrane and stapes footplate.

Q: What sterilization methods are used for this prosthesis?

A: This prosthesis is sterilized using either gamma irradiation or ethylene oxide (EtO), ensuring it is sterile and safe for implantation upon opening.

Q: Is the PORP compatible with MRI scans?

A: Yes, the prosthesis is made from non-magnetic medical-grade fluoroplastic and is deemed MRI safe, so patients with the implant can undergo MRI without concerns.

Q: How should the PORP be stored prior to use?

A: Store the prosthesis in its original, sealed individual packaging in a cool, dry place to maintain sterility. Do not open until immediately before surgical use.

Q: Who is the intended user of this ear prosthesis?

A: The intended users are otolaryngologists and ENT surgeons specializing in middle-ear reconstructive procedures.

Q: What are the main benefits of using this PORP in ear surgery?

A: The PORP offers high anatomical precision, excellent tissue compatibility, real-time surgical adjustability, MRI safety, and reduced infection or allergy risk due to its sterile, non-latex, and corrosion-resistant design.
