Combined endoscopic endonasal and sublabial transmaxillary approaches for resection of intracranially extended juvenile nasopharyngeal angiofibroma.

BACKGROUND

Juvenile nasopharyngeal angiofibromas (JNAs) are rare, benign, and locally invasive nasopharyngeal tumors. Endoscopic endonasal resection is effective, non-invasive, with low complication rates. Until recently, endoscopic resection was not suitable for intracranially invasive tumors.

PURPOSE/METHOD: We describe resection steps of an intracranially extending JNA with a combined endoscopic endonasal and endoscopic-assisted sublabial transmaxillary approaches. Indications, advantages, and approach-specific complications are also discussed. The main surgical steps are shown in an operative video.

CONCLUSION

Surgical excision of JNAs by a combined endoscopic endonasal and sublabial transmaxillary approaches represents a safe and effective treatment for selected intracranially invasive JNA.
