    Basic Functional Endoscopic Sinus Surgery (FESS): A Step-By-Step Guide With Surgical Videos and Illustrations of Anatomical Landmarks in Cadaveric Dissection
    (2025-03-25) Brand, Yves; Prepageran, Narayanan
    We consider four important landmarks in basic FESS. These landmarks are important to gain entry to the maxillary sinus, anterior ethmoid, posterior ethmoid and the sphenoid sinus. Each landmark serves as a gate to a defined space within the paranasal sinuses. This chapter presents an overview to better understand this Gate System. To visualise the different structures of the nose, the nasal cavity is decongested. This can be done with cotton ribbon gauze soaked in Moffat’s solution (1ml adrenaline 1:1000, 2mls 10% cocaine, 4mls 8.4% so-dium bicarbonate, 13mls water/saline) for several minutes. Alternatively, adrenaline 1:1000-soaked cotton ribbon gauze can be used. It is important to pack the middle meatus under endoscopic vision (A).

    Endoscopic Transnasal Optic Nerve Decompression
    (2025-03-08) Lanišnik, Boštjan; Ravnik, Janez
    This chapter focuses on the indications, decision making and surgical technique of endoscopic transnasal optic nerve decompression and presents some controversies relating to decompression for traumatic optic neuropathy. Endoscopic optic nerve decompression can be performed with little or no morbidity. It is done mainly for traumatic optic neuropathy. Other indications include skull base tumours e.g. meningiomas growing into the optic canal. or fibroosseous lesions of the skull base. Endoscopic optic nerve decompression is most suited to pathology located medial to the optic nerve. Lateral fractures of the sphenoid wing e.g. of the clinoid, are more easily accessed through a pterional approach.
