Endoscopic Management of Sinonasal Hemangiopericytoma

Abstract

Endoscopic management of SNHPC is a feasible approach and did not compromise outcomes in this experience. In this series, familiarity with advance endoscopic sinus surgery was necessary to manage these patients. Postoperative adjuvant therapy was not necessary in this cohort.

A population‐based analysis of Head and Neck hemangiopericytoma

“…Head and neck hemangiopericytomas (HN‐HPC) account for 11% to 16% of all HPC . In the head and neck region, they are usually seen in the nasal cavity, orbit, jaw, parotid gland, and oral cavity . Hemangiopericytomas also arise intracranially within the central nervous system (CNS) and account for approximately 0.4% of all CNS tumors…”

Assessment of frontal lobe sagging after endoscopic endonasal transcribriform resection of anterior skull base tumors: Is rigid structural reconstruction of the cranial base defect necessary?

“…In the last decade, there have been significant advances in endoscopic skull base surgery that have allowed surgeons to access and extirpate tumors of the anterior skull base (ASB) and cribriform region using a purely endonasal approach 1–17. While these approaches allow for a less invasive method to remove cribriform lesions than traditional external skull base approaches, the resulting cribriform defects can be quite large, and often extend from the posterior table of the frontal sinus to the tuberculum sellae in the sagittal plane, and from one lamina papyracea to the next in the coronal plane (Fig.…”

Assessment of Mucocele Formation after Endoscopic Nasoseptal Flap Reconstruction of Skull Base Defects

“…[1][2][3][4][5][6][7][8] Although highly effective, these procedures often result in large SB defects that can lead to high-flow cerebrospinal fluid (CSF) leaks. These defects typically necessitate meticulous multilayer reconstruction to prevent postoperative failure.…”
