Anterior approach ptosis surgery: comparison of absorbable polyglactin sutures and non-absorbable polyester sutures....

To determine whether the long-term success of ptosis surgery is influenced by the use of absorbable or non-absorbable sutures to advance the levator aponeurosis onto the tarsal plate.

Multi-centre retrospective comparative study of re-operation rates in primary anterior approach ptosis surgery using absorbable polyglactin sutures (Vicryl) and non-absorbable polyester sutures (Ethibond). The Medisoft audit tool was used to identify all patients who underwent primary ptosis surgery for aponeurotic ptosis, performed by five oculoplastic consultants within a 7-year period, across two NHS Ophthalmology departments. The electronic patient records were reviewed for each patient. Basic demographics, suture material, and post-operative complications were recorded. All patients requiring repeat surgery between the study dates and the present day were recorded, allowing a minimum postoperative period of 3 years and 10 months. Re-operation rates in surgery using absorbable Vicryl sutures and non-absorbable Ethibond sutures were compared using Fisher's exact test.

Four hundred and fifty-five operations in 330 patients were performed within the study period that met the inclusion and exclusion criteria. Fifty-seven percent of the patients were female, with an average age of 68.8 years. One hundred and sixty-nine operations in 128 patients were performed using absorbable Vicryl sutures. Of these, 22 (13.0%) required repeat operations. Two hundred and eighty-six operations in 202 patients were performed using non-absorbable Ethibond sutures. Of these, 17 (5.9%) required repeat operations. The two-tailed P-value was 0.0143.

The use of non-absorbable Ethibond sutures to advance the levator aponeurosis onto the tarsal plate in primary ptosis surgery is associated with improved long-term success and reduced need for secondary surgery.
