CSF Rhinorrhea After Endonasal Intervention to the Skull Base (CRANIAL) — Part 2: Impact of COVID-19

Endoscopic endonasal transethmoidal transcribriform transfovea ethmoidalis approach to the anterior cranial fossa and skull base.

OBJECTIVE The anterior skull base, in front of the sphenoid sinus, can be approached using a variety of techniques including extended subfrontal, transfacial, and craniofacial approaches. These methods include risks of brain retraction, contusion, cerebrospinal fluid leak, meningitis, and cosmetic deformity. An alternate and more direct approach is the endonasal, transethmoidal, transcribriform...

Extended endoscopic endonasal approach to the skull base.

OBJECTIVE Different approaches to the skull base have been developed through the sphenoidal sinus. Traditional boundaries of the trans-sphenoidal approach can be extended in antero-posterior and lateral planes. We review our experience with the extended endoscopic endonasal approach in the first 12 cases. METHODS We used the extended endoscopic endonasal approach in 12 patients with different...

Endoscopic endonasal pituitary and skull base surgery.

Here we describe the procedures of endoscopic pituitary and skull base surgery in our institute. We also review the literature to reveal recent advances in this field. Endonasal approach via the sphenoid ostium was carried out for pituitary lesions without the nasal speculum. Postoperative nasal packing was basically not needed in such cases. For meningiomas, craniopharyngiomas, and giant pitui...

Endonasal Vascularized Flaps For Cranial Base Reconstruction

CSF rhinorrhea complicated by recurrent pyogenic meningitis due to congenital anterior skull base defect: Report of two cases

Cerebrospinal fluid (CSF) rhinorrhea is the result of an osseous defect at the skull base coupled with a disruption of the dura mater and arachnoid with a resultant pressure gradient leading to the CSF leak. Cerebrospinal fluid (CSF) rhinorrhea is a potentially dangerous condition as the risk of intracranial infection is increased if it persists. Therefore, accurate preoperative localization of...
