2 Objective of the StudyTo 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).
5 Materials and Methods - Design 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.
6 Materials and Methods - Design If the flap is extended onto the temporalis fascia up to 50% of the posterior lamella of the lower eyelid can potentially be closed.
7 Materials and MethodsOnce 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.
11 Results and Conclusions 12 patients all with good outcomesThere 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 vascular2. 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.
