The aim of this study is to present novel operation method of delivering both vascular protection and strengthening of the muscles, as well as the transposition of the muscles.
Patients and methods:
The patients’ files were scanned retrospectively. All patients underwent complete eye examination besides motility examination both preoperatively and postoperatively. Follow up of patients were at least six months. Pre- and post-operative deviation measurement values were compared statistically. Operation technique: After being exposed and the rectus muscle is freed from the facial structure as far as planned resection amount. 6-0 coated vicryl sutures are then placed through the two sides of the muscle while protecting the blood vessels. Then, each suture is placed close to the muscle insertion and is aimed at transposition side. For example, if the target is to transpose the superior rectus at temporal side, nasal side suture is placed at temporal edge of muscle insertion and temporal side suture is placed approximately a tendon width laterally to the insertion.
In patients who were planned resection 7 mm and over, the procedure for complete muscle widening transposition was successful. Only 2/3 transpositions could be achieved in 4 patients who underwent less than 7 mm of strengthening. There was no anterior segment ischemia in 3 patients who underwent 3 rectus muscle surgery in the same eye.
‘Sliding shape’ design extra ocular muscle plication found simple, safe and effective procedure for patients who needed resection and transposition operation. More patients and longer follow-up are needed to understand the real effectiveness.
