Endoscopic anterior skull base surgery is a minimally invasive procedure that involves operating on the front part of the skull’s base using an endoscope. This approach is often used to address tumors and other pathologies located at the bottom of the skull or the top of the nasal passages.
Technique: The technique typically involves inserting an endoscope through the nostrils, which provides a direct path to the anterior skull base without the need for external incisions. The endoscope transmits images to a monitor, guiding the surgeon in manipulating micro-instruments to remove abnormal tissue or tumors.
- Rigid Endoscopes: For visualization of the operative field.
- Endoscopic Cameras and Monitors: To display the high-definition images of the surgical area.
- Microdebriders: To carefully cut and remove soft tissue.
- Curved and Angled Instruments: For maneuvering around corners and in tight spaces.
- Suction and Irrigation Equipment: To maintain a clear view by removing blood and debris.
- Navigation Systems: For precise localization of pathology and avoidance of critical structures.
The endoscopic approach to anterior skull base surgery aims to minimize complications and recovery time while maximizing the surgical outcome and preserving key anatomical features and functions.
Indications: Endoscopic anterior skull base surgery is indicated for various conditions, including:
- Benign and Malignant Tumors: Such as meningiomas, craniopharyngiomas, and pituitary adenomas.
- Cerebrospinal Fluid Leaks: To repair defects in the skull base that allow fluid to escape.
- Inflammatory Diseases: Such as sinusitis that extends into the anterior skull base.
- Congenital Anomalies: Conditions present at birth that may affect the skull base.
- Trauma: To address fractures or other trauma-related defects at the skull base.
Micro ear surgery utilizes an operating microscope and precise instruments to treat ear disorders with minimally invasive techniques. It’s indicated for conditions like chronic ear infections, cholesteatoma, and otosclerosis, and can involve procedures like stapedectomy. This approach allows for detailed ear structure visualization, enhancing surgical outcomes and recovery.
