Transnasal surgery, often referred to as transnasal endoscopic surgery or endoscopic transnasal surgery, is a minimally invasive surgical technique that utilizes the nasal passages as natural pathways to access structures within the nasal cavity, paranasal sinuses, and certain areas of the skull base, including the pituitary gland. This approach employs endoscopes and specialized surgical instruments to allow for precise surgical interventions with minimal trauma.

What conditions can transnasal surgery treat?
- Pituitary Tumors: Effective for removing pituitary adenomas and other tumors located in the sellar region.
- Skull Base Tumors: Accesses and removes various skull base tumors, such as meningiomas and chordomas.
- Cerebrospinal Fluid (CSF) Leaks: Repairs leaks in the CSF, which can cause symptoms like clear nasal discharge and increase the risk of meningitis.
What distinguishes transnasal surgery from other surgical approaches?
- Minimally Invasive: Uses the natural anatomical corridors of the nasal passages. Avoids the need for external incisions, which reduces post-surgical scarring and recovery time.
- Endoscopic Guidance: Employs endoscopes equipped with high-definition cameras that provide clear, magnified views of the surgical area on a monitor. Allows for precise navigation and manipulation of instruments within the nasal passages and beyond.
What are the benefits to the patient?
- Reduced trauma and faster recovery.
- No External Incisions: Minimizes the risk of visible scarring and cosmetic concerns.
- Less Postoperative Pain: Generally, results in a more comfortable recovery period.
- Shorter Hospital Stay: Many patients can go home sooner, often within 24-48 hours.
- Reduced Infection Risk: smaller entry points and less disruption lower the risk of postoperative infections.
