Rhinological Outcomes in Endonasal Pituitary Surgery
Rhinological Outcomes in Endonasal Pituitary Surgery
This is a prospective, multi-center observational study designed to address patient-reported
 nasal outcomes in adults undergoing endoscopic and microscopic surgical removal of pituitary
 tumors. The primary objective of this study is to determine the difference in nasal outcomes
 by using the Anterior Skull Base (ASK) Nasal survey between patients treated with endoscopic
 surgical technique and those treated with microscopic surgical technique. Patients will be
 given the ASK Nasal survey to assess their nasal functioning and overall health before their
 surgery, and at post-operative visits 1-2 weeks, 3 months, and 6 months.
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.
