A surgical technique employing orbital septum sutures during ptosis surgery in children is described. A retrospective study of 16 children (age range 6 months to 14 years) undergoing surgery for congenital ptosis over a 6 year period was undertaken with regard to cosmetic outcome. All surgery was performed by one consultant ophthalmic surgeon with the patient under general anaesthesia. A standard levator resection was undertaken, following which the orbital septum was redefined and sutured with interrupted 5-0 catgut. This resulted in a well-defined lid crease post-operatively, with a good cosmetic outcome. The only significant post-operative complication was the occurrence of a suture-related granuloma in one patient. All achieved a good cosmetic result. A mild residual ptosis occurred in 3 cases, requiring a further procedure. Special attention to suturing of orbital septum as a separate tissue layer during levator resection for congenital ptosis gives good lid crease definition which may enhance the overall cosmetic outcome.
