Patient Demographics, Clinical Presentation, and Preoperative Workup Sinonasal mucoceles are benign lesions arising from progressive expansion of respiratory epithelium. Obstruction of the natural ostia of the corresponding sinus leads to…
The frontal sinus is commonly affected by inflammatory diseases, traumatic fractures, benign tumors, and malignant neoplasms. Because of its proximity to the brain, eye, and nose, disease processes originating from…
Right Orbital Subperiosteal Abscess Drainage Acute rhinosinusitis (ARS) accounts for one-fifth of all adult and pediatric antibiotic prescriptions. Bacterial ARS can lead to orbital or intracranial infections by direct or…
Endoscopic-Assisted Orbital Exenteration Malignant diseases involving the orbit can result in an incalculable amount of human suffering, as their natural course can progress to include bleeding, pain, disfigurement, blindness, and…
Osseous tumors represent a broad range of pathologic conditions, which can be roughly categorized into fibro-osseous lesions, cartilaginous lesions, reactive bone lesions, and vascular lesions. Most of these entities are…
Endoscopic orbital surgery represents a challenging arena for the endoscopic surgeon. The orbit is highly complex, with critical structures confined in a fat-filled, soft-tissue space, thereby limiting visibility, and restricting…
The orbital apex is a small, cone-shaped region located between the posterior ethmoidal foramen anteriorly and the openings of the optic canal and superior orbital fissure posteriorly. It contains many…
Orbital tumors encompass a heterogenous range of lesions, from congenital cystic masses to both benign and malignant neoplasms, and can originate from a variety of tissue types. In a large…
Endoscopic endonasal approaches to the skull base are classified by their orientation in the sagittal and coronal planes. The anterior coronal plane corresponds with the anterior cranial fossa and extends…
Postoperative treatment of patients undergoing endoscopic orbital decompression (EOD) shares many similarities with that of patients who have standard functional endoscopic sinus surgery. Important distinctions that must be accounted for…
