  • Abstract
  • Look Inside

A 40-year-old male showed severely impaired visual acuity (v.d.=0.01, v.s.=0), CT scan re-vealed the involvement of bilateral sphenoid sin-uses and clivus. Three weeks after the onset of visual impairment, the operation was done by combined approaches, of transmaxillary, transnasal and transseptal. These combined approaches afforded an improved surgical field and made the subtotal resection of chordoma possible. The visual acuity was soon improved (V.d.=1.2, v.s. =1.0). The postoperative irradiation was followed (60Gy). To the best of our knowledge, this degree of improvement has not previously reported.
