Abstract

Objective

Stage IVb juvenile nasopharyngeal angiofibromas (JNAs) are frequently regarded as unresectable because of their intracranial extension and cavernous sinus invasion. Although radiation has been described to control these tumors, it can leave the adolescent with long-lasting sequelae. Herein, we describe an alternative treatment strategy based on a combined subtemporal-transfacial surgical approach that permits the successful management of advanced stage JNAs by divorcing the intracranial vascular supply to these massive lesions.

Patients

Four male patients were identified with Andrew’s Stage IVB JNAs.

Intervention

All patients were treated by surgical resection using a combined subtemporal-transfacial surgical approach.

Main Outcome Measures

Parameters assessed included tumor extent, number and types of surgical procedures, extent of resections, complications, and recurrence rate.

Results

Near-total tumor resections were achieved in all patients. No cerebrospinal fluid leak or cranial neuropathies were noted. All but one patient had local recurrences, and these could be managed with repetitive endoscopic debridement. No patient required adjuvant radiation treatment to control advanced disease.

Conclusions

With the use of modern skull base surgical techniques, coordinated interdisciplinary care, and safe, near-total removal of the tumor mass, adolescent males with advanced JNAs may be spared the long-term morbidities associated with using radiation to treat these benign but aggressive lesions.
