Treatment outcomes of juvenile nasopharyngeal angiofibroma according to surgical approach.

Abstract

OBJECTIVE: This is a retrospective study to assess treatment outcomes according to stage and surgical approach in advanced juvenile nasopharyngeal angiofibroma (JNA).

METHODS: We retrospectively evaluated 20 JNA patients diagnosed and treated at our hospital. We only enrolled advanced disease with Radkowski stages greater than I and with minimum follow-up of 1 year (range 1-8.5).

RESULTS: Recurrence or remnants were observed in 7 patients out of 20 patients (35.0%) who underwent primary surgical resection of advanced JNA and the mean interval to recurrence was 15.6 months (range 6-38). A recurrence rate according to a different stage was as follows: 33.3% in stage IIa, 33.3% in stage IIb, 50.0% in stage IIc and no recurrence in stage III. An endoscopic approach was chosen in 4 patients among these patients, four were classified as stage IIb tumors, one as a stage IIc tumor, with a recurrence rate of 25.0%, but no recurrence found in stage IIa disease. A midfacial degloving approach was used in 7 patients, with a recurrence rate of 42.9% and maxillary swing approach was taken in 3 patients with complete control. Postoperative complications required interventions occurred in 14.8%, more in the invasive maxillary swing or infratemporal fossa approaches.

CONCLUSIONS: Although selecting minimal invasive or invasive approaches is equivocal, we recommend using the endoscopic approach or a midfacial degloving approach for the treatment of JNA extended to the pterygopalatine fossa. For stage III, aggressive surgery is preferable to guaranty a complete resection even if postoperative complications are more frequent. For a stage IIc, we could choose between a minimally invasive approach or a more aggressive one balancing between the possibility of salvage surgery in the future and the occurrence of postoperative healing problems
