Аннотация
PURPOSE: This study was conducted to evaluate the role of tumor volume in excision of pituitary adenomas.
MATERIALS AND METHODS: A total of 20 patients with pituitary adenoma underwent surgical excision of the tumor by endonasal transsphenoidal approach.
RESULTS: A preoperative tumor volume of more than 5 mL is associated with a 90.90% probability of residual tumor (P < .05, statistically significant).
CONCLUSION: Tumor volume as a predicting factor for the surgical outcome is an evolving concept. Other factors determining the efficacy of tumor removal are parasellar and suprasellar extension.
