Intraoperative endoscopic images. a Localisation of the sphenoid ostium at the sphenoethmoidalrecessus. b–d Creating the right “rescue” nasoseptal flap- from 2 to 3 mm below the sphenoid ostium to the intercutaneomucous point of the nasal vestibule. e The nasoseptal flap was gently folded in the floor of nasal cavity. f A vertical incision of the left nasal septal mucosa was made. g A sufficient binasal access for two-surgeons using the four-handed technique. h–i The binasal mucosa and turbinates were placed back in normal anatomic position. a = sphenoid sinus ostium; b = medial nasal septum; c = the bony nasal septum; d = the right middle nansal turbinate; e = the intercutaneomucous point of the nasal vestibule; f = the vertical incision of the left nasal septal mucosa; g = the left middle nansal turbinate; h = the sphenoid rostrum
