Visual Outcomes Following Endoscopic Endonasal Transsphenoidal Surgery for Pituitary Adenoma

Visual Outcomes Following EETS for Pituitary Adenomas: A Retrospective Study

Abstract

Abstract

Objective: To evaluate the visual outcomes following EETS for pituitary adenomas, focusing on factors influencing postoperative visual recovery and identifying predictors of visual improvement.

Methodology: A retrospective study was conducted, involving 100 patients who underwent EETS at Hayatabad Medical Complex, Peshawar. Data were collected on patient demographics, tumour size, adenoma type, preoperative visual impairment, surgical outcomes, and postoperative complications. Chi-square tests were used to analyse the association between tumour size and visual outcomes, with a significance threshold set at p-value < 0.05.

Results: Out of 100 patients, 58% were male, and 42% were female, with a mean age of 45.2 years. Tumour size distribution showed 30% micro adenomas and 70% macro adenomas. Post-surgery, 60% of patients experienced visual improvement, while 30% maintained their preoperative visual status, and 10% worsened. The p-value for the association between tumour size and visual outcome was 0.01, indicating significant correlation. Complications were low, with 10% transient diabetes insipidus and 5% CSF leaks.

Conclusion: The study concludes that EETS is an effective surgical approach for improving visual outcomes, particularly in patients with macro adenomas and non-functioning adenomas. Early surgical intervention significantly contributes to visual recovery, highlighting EETS as a safe and minimally invasive procedure for managing pituitary adenomas.
