Nasopharyngeal Angiofibroma Staging with a Novel Nominal Basis: An 18-Year Study in a Tertiary Center.

Otolaryngol Head Neck Surg 2019 Aug 23;161(2):352-361. Epub 2019 Apr 23.

2 Department of Otolaryngology-Head and Neck Surgery, Faculty of Medicine, Mansoura University, Mansoura, Egypt.

Objective: To develop a systematic method for anatomic mapping of juvenile nasopharyngeal angiofibroma (JNA) tumors to standardize communication, facilitate surgical planning, and convey prognosis.

Study Design: Retrospective cohort.

Setting: Tertiary referral center.

Subjects And Methods: Following Institutional Review Board approval, we performed a retrospective review of radiologic and angiographic data of patients with JNA presenting to the Department of Otolaryngology-Head and Neck Surgery, Mansoura University, from 2001 to 2017. All patients underwent angiography with embolization and had >1-year follow-up. Based on frequently involved anatomic sites and factors predictive of prognosis, the NSF-COR staging system (nose/nasopharynx, sinus, fossa-cranium, orbit, residual internal carotid artery supply) was developed to explicitly convey anatomic site of involvement and presence of residual vascularity. We validated the NSF-COR staging system against other systems with Pearson chi-square test based on risk factors and clinical outcomes of blood transfusion volume, recurrence, and JNA resectability.

Results: Fifty-four patients met inclusion criteria, where all primary cases (100%) demonstrated nose/nasopharynx involvement, followed by sinus (85.2%), natural fossae (85.2%), intracranial (26%), and orbital involvement (16.7%). These sites, with assessment of residual internal carotid artery vascular supply, were used to develop the NSF-COR anatomically based staging system. The components COR showed significant association with clinical outcomes of blood transfusion and recurrence. Contingency coefficients between the NSF-COR staging system and available staging systems showed significant correlations ( < .05) for prognosis.

Conclusion: The NSF-COR staging system conveys a communicable anatomic map of JNA tumors that integrates residual vascularity of the tumor and demonstrates strong concordance with current staging systems to assess clinical outcomes.
