can also be performed without the use of general anesthesia in many instances. A transoral flexible endoscopic approach successfully reduces cricopharyngeal sphincter pressure [6] . The septum can be divided with a variety of cutting instruments and accessories. It is unknown whether a transoral flexible endoscopic approach will show longterm results compared to rigid surgical therapy for long-...
