- Abstract
- Background : The purpose of this study was to evaluate the clinical utility of preoperative three-dimensional temporal bone reconstruction in patients for translabyrinthine removal of vestibular schwannoma.
Materials and Methods : Prior to commencement of the translabyrinthine approach, critical anatomical structures were traced and three-dimensionally reconstructed using computed tomography (CT) scans of the normal temporal bone. Two patients diagnosed with vestibular schwannoma via magnetic resonance imaging were evaluated in this study.
Results : Anatomical reconstruction allowed sequential planning of the translabyrinthine approach. The patient-tailored, preoperative image-guided approach prevented iatrogenic damage by predicting a high jugular bulb or a narrow sinodural angle.
Conclusions : Three-dimensional reconstruction illuminates the translabyrinthine approach and identifies difficulties that may be encountered at each step, thus preventing confusion. - Keywords : Three dimensional, Computed tomography, Temporal bone, Schwannoma, Vestibular
