Nasotracheal intubation through pharyngeal flap after pharyngeal flap construction

A 24-year-old woman provided her written consent to publish the details of her case. She had undergone multiple surgeries including pharyngeal flap construction for bilateral cleft lip and palate. All previous operations were performed under general anesthesia by oral intubation. In the present procedure, sagittal split ramus osteotomy under general anesthesia with nasotracheal intubation was planned. We obtained the three-dimensional morphological structure of the pharyngeal flap (Fig. 1). The measurements of the cross-section at the narrowest were 5.1×12.8mm for the left orifice and 3.2×13.2mm for the right.
