The Extended Nasoseptal Flap

A 31 year-old male presented with diplopia and was found to have left sixth nerve palsy on physical examination.  Work-up with MRI revealed a hypointense mass on T2 images involving the mid to lower clivus with penetration of the posterior fossa dura.  The patient had no complaints of nasal obstruction, no prior nasal surgery or nasal trauma.  Intraoperative frozen section analysis revealed chordoma.

Author Note: minute 3:41 “rostrum” was spelled incorrectly.
