Endoscopic versus open surgery in patients with malignant sinonasal tumours and brain invasion. A case series study.

Objectives: To determine the safety, effectiveness and perioperative costs of endonasal endoscopic approach in brain invasive malignant sinonsal tumours patients.

Materials And Methods: This was a case series bidirectional study; that included 30 brain invasive malignant sinonsal tumours patients treated by endonasal endoscopic approach (2015-2017) and 53 by open surgery (2010-2015). Propensity score matching was used to compensate the prognostic factors; in a sample of 50 patients (25 per group).

Endoscopic Treatment of Sphenoid Sinus Mucocele: Case Report and Surgical Considerations.

Introduction: The paranasal sinuses mucoceles are benign expansive cystic lesions that occur rarely in the sphenoid sinus and contain mucous material enclosed by cylindrical pseudostratified epithelium.

Objective: To report one case of sphenoid sinus mucocele that occurred with headache and was submitted to surgical treatment through endonasal endoscopy approach.

Case Report: 59-year-old male patient with history of increasing frontoorbital, bilateral, fluctuating headache and exophthalmos.
