2.3 Data
Subjects were asked to complete three symptom assessment questionnaires during their preoperative visit: ETDQuestionnaire (ETDQ-7), SNOT-22, and Nasal Obstruction Symptom Evaluation (NOSE). SNOT-22 includes shared components from both the ETDQ-7 and the NOSE instruments. These questionnaires were completed prior to surgery and again at their routine postoperative visits at 6 and 12 weeks. Primary endpoints of the study were the ETDQ-7 questionnaire scores at the 6-week postoperative visit. In addition to demographics and primary outcomes, secondary outcomes were collected including the severity and laterality of the deviated nasal septum through endoscopic and CT scan measurements.
