Bilateral nasoseptal rescue flaps were elevated in 144 patients (87.3%) and pedicled nasoseptal or middle turbinate flaps in 21 patients (12.7%). The neurovascular pedicles were preserved in all patients, and there were no episodes of postoperative arterial epistaxis. Normal olfaction was noted in 95 patients (86%), with new hyposmia noted in 5 patients (5.5%). Within the rescue flap cohort, new hyposmia occurred in 6.3% (<jats:italic>P<\/jats:italic> &lt;. 01) of patients, balanced by improvement of olfaction in 43% of patients with preoperative dysfunction (overall pre\u2010 and postoperative olfactory function: 85% vs 86%).
