Rhinological Outcomes in Endonasal Pituitary Surgery: A Multi-Center Observational Cohort Study

The technical and patient factors that influence rhinological (nasal) outcomes following
endonasal anterior skull base surgery and pituitary surgery are not well understood. Several
timely and controversial topics, such as the influence of endoscopic techniques and the
impact of underlying disease on nasal outcomes are in need of further study.

The Anterior Skull Base (ASK) Nasal survey is a 24-item questionnaire designed to assess for
common postoperative nasal complaints, such as crusting, nasal congestion, pain, sinusitis,
sense of smell, and overall functioning. The survey is a brief and simple assessment that
asks patients to score symptom severity on a five-point scale.

Inclusion Criteria:

- Pituitary tumor patients treated by transsphenoidal route

- Adults (age 18-80 years)

- Direct endonasal or endoscopic approach

- Non-functioning adenoma, Cushing's disease, acromegaly

Exclusion Criteria:

- Patients treated by expanded endonasal approaches (transtubercular approach)

- Sublabial approach

Type of Study:


Study Design:

Observational Model: Cohort, Time Perspective: Prospective

Outcome Measure:

ASK Nasal symptom severity scores and SF-8 scores

Outcome Description:

Compare symptom severity scores and quality of life scores in first-time surgery patients with nonfunctioning adenomas on the ASK Nasal and SF-8.

Outcome Time Frame:

3 months
