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.
