Visual outcome after fronto-temporo-orbito-zygomatic approach combined with early extradural and intradural optic nerve decompression in tuberculum and diaphragma sellae meningiomas


Mortini, P; Barzaghi, L R; Serra, C; Orlandi, V; Biachi, S; Losa, M (2012). Visual outcome after fronto-temporo-orbito-zygomatic approach combined with early extradural and intradural optic nerve decompression in tuberculum and diaphragma sellae meningiomas. Clinical Neurology and Neurosurgery, 114(6):597-606.

Abstract

OBJECT: The surgical challenge of the treatment of tuberculum (TSMs) and diaphragma sellae meningiomas (DSMs) is to preserve or improve the visual function. Extradural and intradural optic nerve decompression should reduce surgical trauma of the nerve achieving a good visual result.
METHODS: We reported 37 consecutive TSMs and DSMs operated through fronto-temporo-orbito-zygomatic approach with extradural unroofing of the optical canal and early intradural incision of the dural sheath. Visual data were recorded measuring the visual impairment score (VIS), the visual acuity (VA), the visual field (VF) and the postoperative improvement.
RESULTS: A good visual outcome (VIS improved or unchanged) was obtained in 97.2% of patients (35/36). The evaluation of 72 eyes showed a good outcome (VA and VF unchanged or improved) in 98.6% (71/72 eyes). The degree of preoperative VA and VF impairment was the only factor correlating with the postoperative improvement of VA (P<.001 and P=.018) and VF defect (P<.001). Worsening of visual function occurred in 1/37 patient (2.7%).

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
