This is a description of a standardized periosteal bone flap I designed to reconstruct the lateral canthus. The posterior lamella of the eyelid is often left unreconstructed with canthal distortion. This presentation was presented at the American Society of Plastic Surgeons National Meeting in Toronto Canada 2010.

Transcript

  • 1. Optimizing the Periosteal Flap for Lateral Eyelid Reconstruction W. Thomas McClellan, MD FACS Clinton McCord, MD Rebecca Neusch, MD www.mtpsa.com
  • 2. Objective of the Study
    • To establish a standardized method to harvest the periosteal flap in order to improve eyelid strength, position, and reduce ectropion.
  • 3. Materials and Methods - Design
    • Create a central meridian from the upper puncta to the lateral orbital rim.
    • This intersection point is where the superior aspect of the flap is started and continues at a 40 degree angle superiorly out a distance X (which is the length needed to repair the defect).
  • 4. Materials and Methods - Design
  • 5.
    • The width of the flap should measure 6-7 mm which compensates for primary contracture while maintaining strength of the periosteum. The periosteum is then secured with 5-0 Vicryl to the lateral edge of the tarsal plate with enough tension that the lid approximates the globe.
    Materials and Methods - Design
  • 6.
    • If the flap is extended onto the temporalis fascia up to 50% of the posterior lamella of the lower eyelid can potentially be closed.
    Materials and Methods - Design
  • 7. Materials and Methods
    • Once the flap is secured, a Tenzel flap can be rotated to repair the anterior lamellar defect and sutured with 6-0 nylon and 5-0 plain gut near the line margin.
    • Sutures are removed at 6 days.
  • 8. Surgical Images Figure 1 Pre-Op 80% lower eyelid + canthal Defect Figure 2 Intra-Op periosteal flap dissection
  • 9. Surgical Images Figure 3 Periosteal flap reflected to bridge the posterior lamellar defect
  • 10. Post-Operative Images Figure 4 Post-Operative Frontal View Figure 5 Post-Operative Oblique View
  • 11. Results and Conclusions
    • 12 patients all with good outcomes
    • There were no complications such as canthal dehiscence, cicatrical ectropion or entropion.
  • 12. Results and Conclusion
    • The periosteal flap is an ideal flap to repair the lateral canthus and lateral posterior lamella due to its simplicity, reliability, and low risk.
  • 13. Results and Conclusion
    • It can be designed to match the native eyelid contour, originates within the lateral orbit, is strong, and highly vascular 2 . Additionally if the flap relaxes with time it can be elevated and re-secured within the lateral orbit.
  • 14. Significance of the Findings
    • This standardized method demonstrates a reliable method of reconstructing lateral eyelid defects.
    • It optimizes lid position and reduces post operative ectropion.
