Use of balloon-assisted nasal access to augment endoscopic endonasal transsphenoidal approach: illustrative case.

BACKGROUND:Pituitary adenoma is a neurosurgical pathology commonly resected via endoscopic endonasal approach. Septal and nasal passage anatomy can affect the surgical corridor and may require septoplasty or other techniques for expansion. OBSERVATIONS:The authors presented a case of pituitary macroadenoma with septal deviation with use of balloon-assisted nasal access for surgery. LESSONS:This technique enhanced surgical width of field and instrument maneuverability via septal medialization for successful tumor resection.
