The Impact of Endoscopic Pituitary Surgery on Nasal Function

Numerical Simulation Analysis of Nasal Physiology After Endoscopic Pituitary Surgery.

The aim of this study is to determine the impact of endoscopic transsphenoidal pituitary surgery on nasal function using a numerical simulation and to compare the difference between two kinds of transsphenoidal approachese(single nostril approach and bilateral nostril approach)．

Study Overview

• Status: Unknown
• Conditions: Quality of Life; Pituitary Tumor; Endoscopic Surgery; Function of Nose
• Intervention / Treatment: Procedure: Single nostril approach endoscopic transsphenoidal pituitary surgery; Procedure: Bilateral nostril approach endoscopic transsphenoidal pituitary surgery

Detailed Description

Neuroendoscopic surgery is the first treatment for most pituitary adenoma patients. Because transsphenoidal surgery exploits the nasal corridor and paranasal sinuses to reach the skull base, sinonasal trauma is a primary source of postoperative morbidity in many of these patients. The aim of this study is to determine the impact of endoscopic transsphenoidal pituitary surgery on nasal function using a numerical simulation and to compare the difference between two kinds of transsphenoidal approachese(single nostril approach and bilateral nostril approach)．

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Nasal airway patency.	A bilateral model of the human nose on a CT-scan will be reconstructed to display geometric parameters of nasal cavity 3 months after surgery.	Up to 3 months
Airflow patterns.	A bilateral model of the human nose on a CT-scan will be reconstructed. A numerical simulation applying the computational fluid dynamics (CFD) will be performed displaying intranasal airflow patterns 3 months after surgery.	Up to 3 months
Temperature parameter.	A bilateral model of the human nose on a CT-scan will be reconstructed. A numerical simulation applying the computational fluid dynamics (CFD) will be performed displaying intranasal temperature parameter 3 months after surgery.	Up to 3 months
Humidity parameter.	A bilateral model of the human nose on a CT-scan will be reconstructed. A numerical simulation applying the computational fluid dynamics (CFD) will be performed displaying intranasal humidity parameter 3 months after surgery.	Up to 3 months
VAS	Record the Visual Analogue Scale(VAS) 3 months after surgery. The VAS scale includes six sub-scales: rhinorrhea VAS, rhinobyon VAS，rhinocnesmus VAS, cough VAS, sneezing VAS and olfaction VAS. Each scale has a maximum score of 10 and a minimum score of 0. The total VAS was the average of all sub-scales. Higher values represent a better outcome.	Up to 3 months
CT Lund-Mackay Score	Record the CT Lund-Mackay Score 3 months after surgery.The CT Lund-Mackay Score has a maximum score of 24 and a minimum score of 0. Higher values represent a worse outcome.	Up to 3 months
SNOT-20	Record the Sino-Nasal Outcome Record the Test-20(SNOT-20) 3 months after surgery. The SNOT-20 has a maximum score of 60 and a minimum score of 0. Higher values represent a worse outcome.	Up to 3 months
SF-36	Record the Medical Outcome Study Short Form 36-items Health survey(SF-36) 3 months after surgery. The SF-36 includes six sub-scales: General Health, Reported Health Transition，Physical Functioning, Role-Physical, Role-Emotional, Social Functioning, Bodily Pain, Vitality and Mental Health. Each scale has a maximum score of 100 and a minimum score of 0. The total score was the average of all sub-scales. Higher values represent a better outcome.	Up to 3 months
