Survey Anatomical Features and Related Factors of the Sphenopalatine Foramen on Computed Tomography.

The aim of the research is to define anatomical features of the sphenopalatine foramen (SPF) and be related to the SPF on computed tomography (CT) such as shape, location, size of the SPF, the appearance of the ethmoidal crest, and the distance from SPF to some landmarks in the nasal cavity. As a result, surgeons could quickly determine the SPF location in transnasal endoscopic sphenopalatine artery ligation (TESPAL). A cross-sectional study was conducted.

Reconstruction of Large Anterior Skull Base Defects After Resection of Sinonasal Tumors With Intracranial Extension by Using Pedicled Double Flap Techniques.

Introduction: The use of surgical resection for large anterior skull base (ASB) tumors and sinonasal malignancies with intracranial extension will result in a large skull base defect. Reconstruction of large ASB defects using traditional techniques is high risk and may lead to postoperative cerebral spinal fluid (CSF) leakage, meningitis, and an increase in mortality rate. The use of a pedicled double flap technique to reconstruct the ASB defect may decrease complications.

Combined Nasal Endoscopic and Subfrontal Craniotomy for Resection Tumors of Anterior Skull Base.

Objective: Sinonasal tumors invading anterior skull base is difficult to treat in Otorhinolaryngology and Neurosurgery. Treatment requires the collaboration of ear, nose and throat (ENT) and neurosurgeon to remove the tumor completely. This study was to evaluate the outcome of combined technique nasal endoscopic and subfrontal approach in case of sinonasal tumors involving anterior skull base.
