ABSTRACT
Objective To evaluate the clinical efficacy of topical fat redistribution in combination with shortening of upper eyelid levator muscle in patients with excessively wide palpebral fissure after double-eyelid operation.Methods Twenty patients with excessively wide palpebral fissure after undergoing double-eyelid operation were selected.The double-eyelid line was aesthetically re-designed,the skin or incisional scar between the original and new double-eyelid lines was excised,and the scarring adhesion among different tissues was fully isolated.The fat tissues within the orbital septum,deep orbit and anterior orbital septum combined with ROOF reconstruction were performed to block the adhesion tissues,shortening of levator muscle of the upper eyelid was equally conducted to enhance the cosmetic effect.Results Seventeen patients were satisfied with the cosmetic appearance following once double-eyelid operation.Two cases underwent twice operations due to different height between bilateral papebral fissures.One patient was unsatisfied with the cosmetic appearance.Conclusions Fat redistribution in combination with shortening of levator muscle of the upper eyelid can not only repair excessively wide palpebral fissure complicated with ptosis and upper eyelid depression,but also enhance the exposure rate of the cornea and increase the cosmetic appearance,which is consistent with contem porary aesthetic perception.
ABSTRACT
Purpose To investigate clinicopathological features, immunohistochemical findings and differential diagnosis of papillary glioneuronal tumor ( PGNT) . Methods The clinical features, imaging, histological and immunohistochemical findings were analyzed in three cases of PGNT, along with review of the related literatures. Results Two patients were female adults, and the other was male adults. One presented with dizziness, and the other exhibited intractable seizures. Magnetic resonance imaging ( MRI) revealed a cyst-ic space-occupying mass in brain parenchyma of left temporal lobe or right parietal lobe. Microscopically, it was characterized by pseu-dopapillary structures composed of hyalinized vessels rimmed by cuboidal glial cells, oligodendrocyte-like cells and the proliferation of neuronal cells. On immunohistochemical staining, the perivascular cuboidal cells were GFAP-positive, the oligodendrocyte-like cells were Olig-2-positive, and the neuronal cells were synaptophysin-and nuclear protein-positive. Conclusion PGNT is a rare and new variant of mixed neuronal-glial neoplasm, the natural evolution of this tumor is one of low malignant potential and it has a good progno-sis. The distinctive pathologic features help to differentiate this entity from other neoplasm of the central nervous system which has pa-pillary structures.
