Trans-sphenoidal surgery for pituitary tumors advances with the endoscopic approach, offering minimally invasive benefits. Combining endoscopes and microscopes enhances surgical visualization and patient outcomes.
Area of Science:
- Neurosurgery
- Otolaryngology
- Endocrinology
Background:
- Trans-sphenoidal surgery is the primary treatment for pituitary tumors.
- Technological advancements are continuously improving surgical techniques.
- The direct endonasal route and endoscopes represent significant innovations.
Purpose of the Study:
- To review the evolution of trans-sphenoidal surgery.
- To focus on the advantages and applications of the endoscopic approach.
- To highlight the benefits of combining endoscopic and microscopic modalities.
Main Methods:
- Review of current literature on trans-sphenoidal surgery.
- Emphasis on the direct endonasal approach and endoscopic visualization.
- Comparison of endoscopic and microscopic surgical techniques.
Main Results:
- The endonasal approach offers a minimally invasive route with fewer complications.
- Endoscopes provide a panoramic view, overcoming exposure limitations.
- Combining endoscopes with operating microscopes leverages the strengths of both.
Conclusions:
- The endoscopic approach represents a significant advancement in trans-sphenoidal surgery.
- Integrating endoscopic and microscopic techniques optimizes surgical exposure and patient care.
- Further exploration of combined modalities is recommended for pituitary tumor treatment.
