Traditionally, these tumors have been treated with open approaches such as lateral rhinotomy, Caldwell\u2010Luc, or transfacial approaches. Increased experience with endoscopic management of benign and malignant sinonasal tumors has led to a shift in management of SNHPC. The authors present their experience in the largest series of patients with SNHPC managed endoscopically.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design and Setting<\/jats:title><jats:p>Case series at a tertiary care medical center.<\/jats:p><\/jats:sec><jats:sec><jats:title>Subjects and Method<\/jats:title><jats:p>A retrospective chart review of all patients undergoing endoscopic management of SNHPC at the University of Miami between 1999 and 2008 was conducted.

Mean age was 62.5 years (range, 51\u201083 years). There were 6\u00a0men and 6 women. The mean follow\u2010up was 41\u00a0months (range, 15\u201091\u00a0months). Seven (58.3%) presented with nasal obstruction, whereas 4 (41.6%) had epistaxis as their initial presenting symptom. Preoperative angiography or embolization was not performed in any case. Mean estimated blood loss was 630\u00a0mL (range, 100\u20101500\u00a0mL). Six patients underwent endonasal endoscopic anterior skull base resection; 4 had complete endoscopic resection all with negative margins. None underwent postoperative adjuvant treatment.
