[Use of the autologous dorsal dermis in reconstruction of the posterior palpebral lamella in blepharopoiesis]. / Utilisation du derme dorsal autologue en reconstruction lamellaire palpébrale postérieure en blépharopoïèse.

OBJECTIVES: Blepharopoiesis represents a double aesthetic and functional challenge. If anterior lamellar reconstruction is less discussed, the variety of posterior lamellar substitutes testifies that none is ideal. We report here our experience of the use of autologous dermal dermis as posterior lamellar substitutes in bilamellar blepharopoiesis. PATIENTS AND METHOD: We performed a single-center retrospective observational study of seven patients undergoing blepharopoiesis using dorsal dermal autograft as posterior lamellar substitute. RESULTS: Between September 2011 and January 2017, seven patients aged of 80.9 years on average were cared for. The defect, affecting in 6 cases on 7 the lower eyelid, concerned almost three-quarter of the length of the eyelid. These defects followed the excision of basal cell carcinomas. Procedures performed under local anesthesia have simple follow-up without complications of the donor site. The superficial surface of the graft in contact with eyeball was covered in 2.4 months with a non-keratinized squamous epithelium like the conjunctiva. Two patients presented ocular functional signs during 2 months without keratitis. Two patients required a second correction procedure. CONCLUSION: The use of the dorsal dermis seems reliable, simple, fast, possible under local anesthesia and sedation, achievable in one operative time, outpatient, without temporary tarsorraphy. The graft is available in large quantities and its removal is not morbid. The good functional and esthetic results suggest that the autologous dermal dermis could represent the main alternative to palatal fibromucosa as a posterior lamellar substitute in old population.
