Summary
A transmalar Steinmann pin provides immediate, stable anchorage for midface prostheses in patients with extensive defects. This effective method offers long-term retention with minimal complications, simplifying complex reconstructions.
Area of Science:
- Oral and Maxillofacial Surgery
- Craniofacial Reconstruction
- Biomedical Engineering
Background:
- Extensive bilateral midfacial defects pose significant reconstructive challenges.
- Stability of prosthetic restorations is crucial and often compromised by orofacial motion.
- Existing methods may lack immediate or permanent anchoring solutions.
Purpose of the Study:
- To evaluate the efficacy of transmalar Steinmann pin placement for immediate and permanent retention of midface prostheses.
- To assess the long-term stability and complication rates associated with this technique.
Main Methods:
- A series of eight patients with extensive midfacial defects underwent transmalar placement of a Steinmann pin during tumor resection.
- The pin was immediately utilized to anchor a prosthesis to the skull base.
- Patient follow-up extended up to 9 years.
Main Results:
- The transmalar Steinmann pin demonstrated firm anchorage in six of the eight patients.
- No major complications were reported related to the use of the Steinmann pin.
- The technique provided immediate and stable prosthetic retention.
Conclusions:
- The transmalar Steinmann pin is an effective, single-stage solution for permanent midface prosthesis retention.
- This method addresses the challenge of achieving stable prosthetic anchorage in complex craniofacial defects.
- It offers a reliable and safe approach for improving patient outcomes in maxillofacial reconstruction.
