ABSTRACT Juvenile nasopharyngeal angiofibroma (JNA) is a benign, highly vascular, and locally invasive tumor. Because the location of these tumors makes conventional surgery difficult, interest in endoscopic resection is increasing, particularly for the treatment of lesions that do not extend laterally into the infratemporal fossa. We report the results of our series of 23 patients with JNA (stage IIB or lower) who underwent transnasal endoscopic resection under hypotensive general anesthesia without preoperative embolization of the tumor All tumors were successfully excised. The amount of intraoperative blood loss was acceptable. We observed only 1 recurrence, which was diagnosed 19 months postoperatively in a patient with a stage IIB primary tumor. We observed only 3 complications during follow-up-all synechia. We conclude that endoscopic resection of JNAs is safe and effective. The low incidence of recurrence and complications in this series indicates that preoperative embolization may not be necessary for lesions that have not undergone extensive spread; instead, intraoperative bleeding can be adequately controlled with good hypotensive general anesthesia.

    ABSTRACT: Juvenile nasopharyngeal angiofibroma is a histologically benign, but very aggressive and destructive tumor found exclusively in young males. The management of juvenile nasopharyngeal angiofibroma has changed in recent years, but it still continues to be a challenge for the multidisciplinary head and neck surgical team. OBJECTIVE: The purpose of this study was to review a series of 30 patients describing the treatment approach used and studying the outcome of juvenile nasopharyngeal angiofibroma in the ENT Department Timisoara, Romania for a period of 30 years. METHODS: The patients were diagnosed and treated during the years 1981-2011. All patients were male. Tumors were classified using Radkowski's staging system. Computed tomography and magnetic resonance imaging allowed for accurate diagnosis and staging of the tumors. Biopsies were not performed. Surgery represented the gold standard for treatment of juvenine nasopharyngeal angiofibroma. All patients had the tumor removed by an external approach, endoscopic surgical approach not being employed in this series of patients. RESULTS: All patients were treated surgically. Surgical techniques performed were: Denker-Rouge technique in 13 cases (43.33%), paralateronasal technique in 7 cases (23.33%), retropalatine technique in 5 cases (16.66%) and transpalatine technique in 5 cases (16.66%). No preoperative tumor embolization was performed. The recurrence rate was 16.66%. The follow-up period ranged from 1 year to 12 years. CONCLUSIONS: Management of juvenile nasopharyngeal angiofibroma remains a surgical challenge. Clinical evaluation and surgical experience are very important in selecting the proper approach. A multidisciplinary team, with an experienced surgeon and good collaboration with the anesthesiologist are needed for successful surgical treatment.

    ABSTRACT: Management of vascular tumors of the head, neck, and brain is often complex and requires a multidisciplinary approach. Peri-operative embolization of vascular tumors may help to reduce intra-operative bleeding and operative times and have thus become an integral part of the management of these tumors. Advances in catheter and non-catheter based techniques in conjunction with the growing field of neurointerventional surgery is likely to expand the number of peri-operative embolizations performed. The goal of this article is to provide consensus reporting standards and guidelines for embolization treatment of vascular head, neck, and brain tumors. This article was produced by a writing group comprised of members of the Society of Neurointerventional Surgery. A computerized literature search using the National Library of Medicine database (Pubmed) was conducted for relevant articles published between 1 January 1990 and 31 December 2010. The article summarizes the effectiveness and safety of peri-operative vascular tumor embolization. In addition, this document provides consensus definitions and reporting standards as well as guidelines not intended to represent the standard of care, but rather to provide uniformity in subsequent trials and studies involving embolization of vascular head and neck as well as brain tumors. Peri-operative embolization of vascular head, neck, and brain tumors is an effective and safe adjuvant to surgical resection. Major complications reported in the literature are rare when these procedures are performed by operators with appropriate training and knowledge of the relevant vascular and surgical anatomy. These standards may help to standardize reporting and publication in future studies.

    ABSTRACT: OBJECTIVES/HYPOTHESIS: This study is a review of the treatment outcomes of juvenile nasopharyngeal angiofibroma (JNA) specifically comparing endoscopic, endoscopic-assisted, and open surgical approaches. STUDY DESIGN: Systematic review of studies using the MEDLINE database. METHODS: A systematic review of studies on JNA from 1990 to 2012 was conducted. A search for articles related to JNA, along with bibliographies of those articles, was performed. Articles were examined for individual patient data (IPD) and aggregate patient data (APD). Demographics, presenting symptoms, surgical approach, follow-up, and outcome were analyzed. RESULTS: Eighty-five articles were included, with IPD reported in 57 articles (345 cases) and APD in 28 articles (702 cases). For the IPD cohort, average follow-up was 33.4 months (range, 0.5-264 months). Average blood loss was 544.0 mL, 490.0 mL, and 1579.5 mL for endoscopic, endoscopic-assisted, and open surgical cases, respectively (P < .05). Recurrence rate following endoscopic surgery and open surgery were significantly less than endoscopic-assisted surgery (P < .05). In the APD cohort, the recurrence rate following endoscopic surgery was 4.7% compared to 20.6% in the endoscopic-assisted group and 22.6% in the open surgery group (P < .05). Among studies that reported Radkowski/Sessions grading, there was no significant difference in recurrence rates for both the IPD and APD cohorts across each stage between open and endoscopic surgery (P > .05). CONCLUSIONS: In this study, endoscopic resection had a significantly lower intraoperative blood loss and lower recurrence rate when compared to open resection. However, there was no difference in recurrence rate when analyzing the IPD and controlling for Radkowski/Sessions grading. Therefore, further large-scale studies may be required to fully elucidate treatment options. LEVEL OF EVIDENCE: 3a. Laryngoscope, 2013.
