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.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
