Summary
Expanded endoscopic approaches provide access to the entire cranial base, including complex areas like the cavernous sinuses and orbit. This review details these surgical techniques for skull base surgery.
Area of Science:
- Neurosurgery
- Otolaryngology
- Endoscopic Surgery
Background:
- Surgical endoscopy has advanced, enabling transnasal access to extensive cranial base regions.
- Expanded endoscopic approaches facilitate visualization of critical anatomical structures.
Purpose of the Study:
- To review established endoscopic approaches to the cranial base.
- To illustrate these techniques using intraoperative and cadaveric images.
Main Methods:
- Transnasal endoscopic techniques are employed.
- Lateral scope manipulation allows exploration of coronal plane structures.
- Procedures are demonstrated via intraoperative and cadaveric photographs.
Main Results:
- Nearly the entire cranial base is accessible via transnasal endoscopy.
- Frontal sinuses, cribriform plate, planum sphenoidale, suprasellar space, clivus, and upper cervical spine are reachable.
- Lateral scope positioning visualizes cavernous sinuses, Meckel cave, and orbits.
Conclusions:
- Transnasal endoscopic approaches offer comprehensive access to the cranial base.
- These expanded techniques are integral to modern endoscopic skull base surgery.
