Reconstruction of full-thickness upper eyelid defects often requires repair of both the anterior lamella (skin and orbicularis oculis muscle) and the posterior lamella (tarsus and conjunctiva). Various autogenous grafts have been used for posterior lamellar reconstruction, but it is still unclear which material is most suitable for repairing the posterior lamella. We report a patient in whom a subtotal defect of upper eyelid was reconstructed with a bipedicled myocutaneous flap lined by hard palate mucoperiosteum. We also examined tarsoconjunctiva, labial mucosa, hard palate mucoperiosteum, and auricular cartilage histologically and assessed the histologic features of these tissues as substitutes for the posterior lamella. An even and stable upper eyelid was formed by our method of reconstruction. A mucoperiosteal graft from the hard palate bears a close resemblance to the tarsoconjunctiva histologically because it contains both fibrous connective tissue and a mucous membrane. The graft took completely and there was no donor site morbidity or postoperative complications. A hard palate mucoperiosteal graft may be an optimal substitute for the posterior lamella of the upper eyelid.
Meningioangiomatosis is rare disease and is classified as hamartoma in central neurofibromatosis. Unlike most cases of meningioangiomatosis, the very rare case reported here was not associated with von Recklinghausen's disease. We could find only 12 previous cases reported in the literature. A review was carried out of the clinical features, imaging characteristics, and histopathological findings in those 12 plus ours for a total 13 cases. Several types of convulsion were identified as clinical symptoms in 11 of the 13 cases. They were treated surgically. Prognosis was satisfactory in most cases. Proliferation of small blood vessels accompanied by endothelial cells with glial tissue as background and proliferation of fibroblasts or meningothelial cells in the perivascular space were observed to be the most frequent histopathological features.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
