ABSTRACTObjective: To classify patients with nasopharyngeal angiofibromas and to investigate their clinical and paraclinical profiles, treatments received, course and complications.
Date and place: Otorrinolaringology Service at the National Institute of Pediatrics of Mexico City, between 1992 and 2002.
Design: Retrospective, longitudinal, descriptive, observational study.
Material and methods: Every patient with nasopharyngeal angiofibroma, a complete clinical and radiological file which included computed tomography was selected and classified according to Chandler’s stadification. The following information was collected: whether the patient received treatment in another Service, clinical and paraclinical characteristics, treatment, and course. The information obtained was described both graphically and numerically. To statistically compare continuous variables in terms of Chandler’s classification, a two-tailed, alpha=0.05, Kruskal-Wallis test was performed. Results: Nineteen patients fulfilled the selection criteria and were staged as: Chandler II, 4 patients; Chandler III, 7; Chandler IV, 8. All patients in Stages II and III were operated. Four patientes in Stage II received other treatments in other Services; five patients in Stage IV, were not operated because of the large size of the intracraneal extension of the tumor. In two of the three remaining patients degloving was performed, in another one a combined approach was used, i.e., degloving for removal of the extratemporal tumor and an intracraneal approach for the intracraneal tumor.
Discussion: For patients in Chandler’s stage II and III, surgery was the elective treatment; 2/5 patients in Stage IV were not operated since they were asymptomatic.
