Area of Science:

Neurosurgery
Endoscopic Surgery
Pituitary Disorders

Background:

The transsphenoidal approach is a key surgical technique for pituitary lesions.
Traditional microscopic methods have limitations in visualization and maneuverability.

Purpose of the Study:

To evaluate the efficacy and safety of the endoscopic transsphenoidal approach.
To compare endoscopic techniques with traditional microscopic transsphenoidal surgery.

Main Methods:

Comparative studies analyzing endoscopic transsphenoidal surgery versus microscopic transsphenoidal surgery.
Assessment of tumor resection rates, hormonal remission, and complication rates.

Main Results:

Endoscopic transsphenoidal surgery shows equivalent or improved tumor resection rates.

Equivalent or lower complication rates observed with the endoscopic approach.

Enhanced visualization, illumination, and surgical freedom with endoscopic techniques.

Conclusions:

The endoscopic transsphenoidal approach provides significant advantages for pituitary lesion treatment.
Improved surgical outcomes are attributed to enhanced visualization and advanced instrumentation.
Endoscopic surgery promotes maximal tumor resection while preserving the pituitary gland.
