Abstract

Endoscopic resection has become an established surgical option for most juvenile nasopharyngeal angiofibromas (JNA). However, surgical management of JNA with intracranial extension remains challenging. This retrospective multicenter study reviews a series of patients with advanced stage JNA treated via endonasal/endoscopic approach.The experience of five academic tertiary or quaternary care ORL-HNS Departments were included. Medical records of all patients operated for JNA staged as Radkowski stage IIIA or IIIB were reviewed. Main outcome measures included intraoperative blood loss, length of hospital stay, complication rate, and rate of persistence or recurrence.A total of 74 male patients with stages IIIA and IIIB were included. The mean age was 16.4 years and preoperative embolization was performed in 71 patients. The mean blood loss in 45 patients for whom the data was available was 1279.7 ml. The more anatomic subsites were involved, the higher the risk was of intraoperative bleeding. The mean follow-up for 54 out of 73 patients was 37.9 months. Patients with residual disease are significantly linked to involvement of combined (anterior-lateral and posterior) anatomic subsites and to a higher number of affected subsites. At last follow-up, all patients were asymptomatic and those with residual tissue displayed no imaging signs of growth.This retrospective multicenter study supports the notion that expanded endonasal endoscopic approaches for advance staged JNA are a feasible option associated with good long-term results.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-08-18:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 27.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 39 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 0.25.
  • The number of mentions on the social network X (formerly Twitter): 1 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
