Juvenile nasopharyngeal angiofibromas (JNAs) are highly vascular and benign tumors that can expand into the skull base. Delay of treatment can result in intracranial invasion, requiring extensive open approaches such as a facial translocation, maxillary swing, or an orbitozygomatic craniotomy. We describe a single-stage, combined endoscopic and transoral approach on a 14-year-old male with extensive high-stage dumbbell-shaped JNA involving the infratemporal fossa, orbit, buccal space, and intracranial extension into Meckel's cave. Successful resection of the tumor and good postoperative outcome was achieved. A transoral approach allowed for greater access to the infratemporal fossa, where endonasal resection was not possible, allowing for improved visualization, greater traction, and dissection. In select highly staged JNAs with significant lateral extension and intracranial involvement, successful and complete resection may be accomplished with this combined approach. Utilization of this approach avoids the morbidity of more invasive open approaches.

Purpose Multiple surgical approaches have been described to maximize visualization and accessibility for resection while minimizing morbidity in the patient with orbital intraconal tumors. Transnasal endoscopic approaches have become increasingly standard in select orbital cavernous venous malformations but often require a partial septectomy. The purpose of this manuscript is to communicate a septal preserving modified transseptal approach. Methods A 37-year old male was found to have an inferomedial intraconal orbital mass, measuring up to 2.6 cm on magnetic resonance imaging. Binarial transseptal access with septal preservation was obtained with a Killian incision on the right and a small incision in the midseptum on the left. Results Successful tumor delivery through the nasal cavity resulted in orbital relaxation. Postoperative evaluation of the septum demonstrated an intact septum with nearly no evidence of septal trauma from surgical manipulation. Conclusion This technique is easily performed and affords adequate visualization and freedom of movement as traditional binarial transseptal approaches without the disadvantages of partial septal loss such as increased crusting, olfactory disturbance, and loss of nasoseptal flaps.
