USE OF AUGUMENTED REALITY IN TREATMENT OF PITUITARY MICROADENOMAS

Abstract

Introduction Transsphenoidal surgery, performed using endoscopic or microscopic techniques, is a safe and effective method for treating neuroendocrine pituitary tumors, including microadenomas. However, the precise location of microadenomas can be challenging to determine, particularly in acromegaly patients, who often exhibit a reduced intracarotid distance. Augmented reality (AR), particularly through heads-up displays (HUD) integrated into surgical microscopes, has been predominantly utilized in transcranial approaches but shows potential in enhancing transsphenoidal procedures. Aim This study aims to present the surgical workflow, techniques, and outcomes associated with using AR in microscopic transsphenoidal surgery for pituitary microadenomas. Material and Methods All procedures were conducted at the Targu Mures Clinical Emergency Hospital’s Department of Neurosurgery between 2019 and 2024. A total of 15 cases were treated using AR-assisted techniques. While the surgical operative time was comparable to non-AR-assisted procedures, the preoperative setup was more time-consuming and required staging to optimize the surgical workflow. In all cases, surgeons successfully identified and resected the microadenomas without complications related to navigation accuracy. Conclusions The findings suggest that integrating AR into transsphenoidal surgery enhances anatomical understanding and precise localization of microadenomas, providing a valuable tool for neurosurgeons. However, AR cannot replace surgical expertise and clinical judgment.
