Craniofacial Resection for Malignant Tumors of Ethmoid and Anterior Skull Base

Impact of Dural Resection on Sinonasal Malignancies with Skull Base Encroachment or Erosion

“…Although there did not seem to be significant differences in the histopathologic grades, the variability of histopathology in the various groups may confound the oncologic results. 3,6,17,18,21,34,35 In addition, the sample size of the present study was small, thus limiting the overall power to detect oncologic differences between groups. The power was further reduced by the incomplete reporting of pathologic evidence of dural invasion in those who had dural resections completed.…”

“…16 The most common failures of these tumors are locoregional, thus emphasizing the importance of complete resection and adjuvant therapy. 5,7,[16][17][18] Margin status has been shown to be the most significant histopathologic predictor of all outcome parameters, including local and regional recurrences. 7,19,20 In the present study, we demonstrate that patients with dural resections are more likely to achieve negative margins.…”

Complications of anterior craniofacial resection

“…[9][10][11][12][13][14][15] Our series of anterior CFRs includes 65% of patients with advanced skin tumors, 20% with paranasal sinus tumors, and 25% with miscellaneous sites including nasal fossa, nasopharynx, orbit, and soft tissue. The high incidence of skin tumors in our series, which is unusual if compared with other series, [5][6][7][8][9][10][11][12][13][14]19 may be due to Brazil's tropical climate being associated with certain Abbreviation: CFR = craniofacial resection. factors linked to an increase in aggressive behavior and in recurrence rates of these tumors, such as location in areas of embryologic fusion, in the naso-orbital region, and lesions with previous therapeutic attempts using surgery and radiotherapy.…”

Utilization of Artificial Dura for Anterior Skull Base Reconstruction Following Transcranial Resection of Benign Cranionasal Communicating Tumors: Technical Note

“…In 1977, the frontal pericranial flap was introduced for ASB defect repair. 12 13 Johns et al 3 defined the pericranial flap as a combination of the periosteum and the loose connective tissue. The microvascular surgery pioneered by Jacobson and Suarez, 28 in the 1960s, paved the way for MVFTT.…”
