Inclusion criteria

Inclusion criteria: 1. Age >= 18 years; 2. Pituitary adenoma confirmed by preoperative MRI and postoperative pathology, suitable for transsphenoidal surgery; 3. First operation, no history of previous transnasal skull base or sphenoid sinus surgery; 4. Preoperative nasal endoscopy and paranasal sinus CT showing well-developed sphenoid sinus, identifiable sphenoid ostium, and no severe sinusitis; 5. Able to cooperate with olfactory testing and follow-up assessments, and signed informed consent.

Exclusion criteria

Exclusion criteria: 1. Patients requiring significantly extended endonasal approach for resection of extensive parasellar, suprasellar or frontal basal tumors with anticipated high-flow cerebrospinal fluid (CSF) leakage; 2. Severe anatomical abnormalities of the nasal cavity (severe nasal septum deviation, multiple nasal polyps, fungal sinusitis, etc.); 3. Preoperative moderate to severe olfactory dysfunction or severe nasal diseases; 4. Complicated with severe systemic diseases intolerant to surgery or long-term follow-up.
