Abstract: Objective To investigate the indications,approaches,and essentials of cranio-orbital surgeries for orbital apextumors.Methods The clinical data of 48 patients with orbital apextumors treated by refined transcranial orbitotomy through superolateral approach were analyzed retrospectively,34 tumors were excised with orbitoptenonal approach,while 14 tumors were excised with orbltotrontal approach,orbitozygomatic approach,or zygomatic-ptefional approach.Results Of the 48 orbital apextumors,33 cases were totally resected,7 cases were subtotally resected,and 6 cases were partly resected.The other 2 cases were taken biopsies.The optic functions improved or retained in 40 cases,7 cases suffered from eye-moving disfunction or visual-acuity declines,and 1 case suffered from hemiparalysis.Conclusions Tumors in the posterior and apex part of the orbit,or tumors extended from the orbit to the cranial,can be well treated through transcranial approach.Appropriate methods may help to bring maximum convenience to exposure and excision of the lesion,and to conserve the functions.Unnecessary injuries could be avoided as well.
