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.
