INTRODUCTION: Retraction of the lower eyelids has multiple etiologies. Its surgical treatment is a vertical elongation of the tarsus. This can be obtained by using a graft. We describe a sampling and grafting technique using palatal fibromucosa intratarsal graft.
TECHNICAL NOTE: The procedure is performed in two steps under general anesthesia. The graft is harvested on the lateral sides of the palatine vault to avoid neurovascular bundles. This area corresponds to the maxillary fibromucosa according to Delaire's classification. The graft is then inserted in the lower eyelid tarsus.
DISCUSSION: Many "spacers" are available to extend the posterior lamella vertically; the palatal fibromucosa graft may be used directly and is easy to harvest. It has a similar stiffness to that of the tarsus and there is no need to harvest periosteum. Sparing the periosteum allows for a better healing of the donor site and decreases postoperative pain. The lateral harvesting area, away from the anterior palatine artery, seems more accessible than the median area, especially in ogival palates.
