Welcome to the International Survey on Clinical Variation in surgical treatment of iSGS

Idiopathic subglottic stenosis (iSGS) is a rare condition, commonly affecting middle-aged female Caucasian patients, and characterised by circumferential fibrotic stenosis of the subglottic larynx and upper trachea. We are interested in what techniques are most commonly used internationally to treat iSGS. There might be clinical variation based on availability of equipment, organisation of care and training. We are also interested in your attitude towards other surgical techniques that you might not use or might not be acquainted with yet. All surgical techniques, including endoscopic, open and in-office treatment are taken into account in this questionnaire. All physicians that treat iSGS, including otolaryngologists, thoracic surgeons and interventional pulmonologists, are approached for participation. 
 
 
Participation is voluntarily and anonymously. Data will be published in a peer-reviewed article. By continuing the questionnaire, you acknowledge the information presented above and freely consent to participate in this study. The questionnaire will take you approximately 10-30 minutes, depending on the variation of surgical techniques you use.

Your participation would be greatly appreciated!
