To characterize the clinical and pathologic features of lower eyelid trichiasis and to report a new surgery technique.
A prospective study involving lower eyelid trichiasis carriers at Hospital Estadual Bauru and Faculdade de Medicina de Botucatu, UNESP, Brazil was done to recognize the clinical and histological features of this affection and the results after a new surgical procedure. Consecutive patients were included in the year 2009 to 2011. The surgical procedure involves the resection of the affected anterior lamella and margin eyelid reconstruction using advanced graft composed by orbicularis muscle and adjacent skin. The removed specimens were included, stained by hematoxylin-eosin and were histologically evaluated. The patients were followed 7, 30 and 90 days after surgery.
The procedure was done in 56 lower eyelids of 49 patients (23 men, 26 women); age range 51-98 years; mean age 70,65 years old. Elastosis, actinic keratosis and chronic blepharitis were the most important histological features. In the outcome of all patients it was not observed any misdirected eyelashes and the procedure was achievable and well succeeded.
The lower eyelid trichiasis affected both sex, mainly old patients. The authors agree the resection of the affected anterior lamella technique is a good option to treat lower eyelid trichiasis.
