Illustration of the one-and-a-half nostril endoscopic transsphenoidal approach. a Creating the right “rescue” nasoseptal flap. The blue line shows mucosal cutting line: from 2 to 3 mm below the sphenoid ostium to the intercutaneomucous point of the nasal vestibule. If anasoseptal flap is necessary, the yellow mucosal cutting line is made: along the floor of the nasal cavity from the choanae to the front of the first incision. b One-and-a-half approach: a vertical incision of the left nasal septal mucosa was made, which extended approximately 2 cm at the anterior-level of the middle turbinate. Binostril approach: a part of left posterior septal mucosa was necessarily resected
