Craniofacial Resection of Frontal Sinus Tumor


  • Malignant tumor of frontal sinus
  • Locally aggressive benign sinonasal neoplasm


  • Endoscopic transnasal approach for removal of inferior portion of tumor
  • Bifrontal craniotomy for removal of superior portion of tumor
  • Closure of skull base defect with pericranial and temporalis fascia flaps

Keep in Mind/Things to Remember:

  • Orbital decompression with removal of lamina papyracea may be performed to control lateral tumor margin.
  • A water tight closure is necessary to reduce the incidence of postop CSF leak.
  • Use of vascularized flaps is beneficial to patients who require postop radiation therapy.
