Comparing success rates of two surgical techniques for involutional entropion of the lower eyelid: the everting sutures and the lateral tarsal strip.

None listed

The surgical treatment of the involutional entropion of the lower eyelid by using two techniques: 1. the everting sutures and 2. the lateral tarsal strip technique. Prospective randomized comparative study of these two techniques. I want to find which is the best procedure, the outcome of anatomical and functional recovery over time and their contribution to improving patients’ quality of life. SURGICAL TECHNIQUES: 1. the everting sutures technique: It consists in the insertion of three (3) absorbable sutures 6.0 with double needle obliquely from the lower limit of the palpebral conjunctiva through the skin of the eyelid below the eyelashes. 2. the lateral tarsal strip technique: Cantholysis of the lateral palpebral ligament. Preparation of an outer tarsus flap (sling) by removing the dermis, the orbicularis muscle and the conjuctiva. Flap fixation by using sutures 5.0 to the temporal orbit periosteum . Wound restorarion by using 6.0 sutures. Based on the existing literature, there are some questions to be answered: Which is the most appropriate surgical rehabilitation technique for the lower involutional eyelid entropion with the best success rates, fewer complications and the lower recurrence rates? Importance: The result of the investigation may lead to the predominance of one technique over the other and to establish criteria for their selection.
