Endoscopic Techniques in Resection of Anterior Skull Base/Paranasal Sinus Malignancies

Abstract

With complete endoscopic surgical resection followed by radiation therapy, local recurrence, morbidity, and cosmetic deformity have been minimized. The microscopic view provided by endoscopic techniques, with or without complementary approaches, allows for complete tumor removal.

Surgical outcomes of malignant sinonasal tumours: open versus endoscopic surgical approaches

“…The endoscopic approach is associated with less post-surgical morbidity and better cosmetic outcomes as no facial incisions are required. 4,11 It can yield the same oncological treatment results as the traditional approach, even in advanced cases with skull base involvement. 12,13 Many studies have investigated the efficacy of the endoscopic approach for treatment of sinonasal malignancies.…”

“…16 A combined approach, using conventional techniques with the endoscopic technique, has been shown to have promising results in patients with more advanced tumours. 11 Some authors recommend endoscopic resection for more advanced tumours with skull base involvement. 12,13 For instance, Carrau et al state that transnasal endoscopic surgery is an outstanding approach for the treatment of sinus and skull base tumours.…”

“…In some reports, it is considered an efficient method. 1,[11][12][13][14][15][16][17][18][19][20][21][22] Some consider it to be the treatment of choice for inverted papilloma. 23 Others do not consider it as a replacement for the traditional craniofacial approach.…”

Endoscopic Resection of Advanced Anterior Skull Base Lesions: Oncologically Safe?

“…Initial authors described skull base surgery in the context of continued bifrontal craniotomy, sparing the cosmetic effects of a facial incision [4][5][6] . More recent authors have described entirely endoscopic techniques, sparing both facial incisions and the morbidity of craniotomy [7][8][9][10][11][12] . Avoidance of piecemeal techniques is a theoretical advantage of CFR over endoscopic techniques.…”
