RESUMEN
INTRODUCTION: The open frontal intersinus septum takedown (FISST) technique was first described in 1976. We describe our experience with an endoscopic transnasal approach to manage a frontal sinus pyocele arising from an obstructed frontal sinus outflow tract due to anterolateral thigh flap reconstruction of a maxillectomy defect. CASE REPORT: A 40-year-old lady experienced upper eyelid swelling and purulent nasal discharge 3 weeks after undergoing a left extended medial maxillectomy with free anterolateral thigh flap reconstruction. A computed tomography (CT) scan revealed total opacification of the left frontal sinus. There was no improvement with intravenous antibiotics and she underwent a surgery, whenshe was found intraoperatively to have a frontal sinus pyocele, which was then drained. She then underwent an endoscopic transnasal FISST to ventilate the left frontal sinus via the contralateral frontal recess with good results. A CT scan performed 3 months postoperatively showed a widely patent interfrontal sinus septal window and right frontal outflow tract with no disease recurrence. DISCUSSION: The FISST is a useful technique to manage unilateral frontal sinus disease by taking advantage of the contralateral outflow tract when the ipsilateral frontal recess is obstructed.

BACKGROUND: Optic neuritis resulting from paranasal sinusitis is an infrequently described but clinically important and treatable entity. The role of optic nerve decompression has been well established in atraumatic optic neuropathies which are compressive in origin. However, its role in optic neuritis and other infective or inflammatory processes is lacking, and the role for early surgical intervention remains controversial. CASE REPORT: In this case report, we describe a patient who presented with sudden onset of right vision loss secondary to optic neuritis from pansinusitis. He was treated with systemic antibiotics and steroids along with an urgent endoscopic sinus surgery with optic nerve decompression. Full restoration of his vision was recorded within 24â¯h of surgical decompression. CONCLUSION: Optic neuritis secondary to paranasal sinusitis is a clinically important entity and timely diagnosis and decompression is key to vision restoration.
