We have made a retrospective study of six cases of juvenile nasopharygeal angiofibroma stage III.A and one case of a large osteoma of the ethmoid labyrinth, all of them treated surgically through a bilateral horizontal osteotomy of the maxilla, Lefort I, with very good results. This is a new technique that has been used for the first time in our hospital, facilities the exposure of the skull base and sorrounding structures and allows a complete removal of the tumor with good control of the hemostasis, minimal blood loss and leaving no disfiguring scar on the face. The technique is described in detail (An Fac Med UNMSM II Epoca 1989; a (1-2): 45-48).

Objectives: To describe the surgical handling of juvenile nasopharyngeal angiofibroma, both approach and anesthesia, to demonstrate compromise and staging and to determine complications and recurrence of juvenile angiofibroma using Le Fort I approach. Design: Retrospective descriptive study. Setting: Head and Neck Surgery Department, Hospital Dos de Mayo. Participants: Patients with pathology confirmed juvenile nasopharyngeal angiofibroma. Interventions: We reviewed all the cases with surgery for juvenile nasopharyngeal angiofibroma confirmed by pathology between January 1993 and December 2006. Main outcome measures: Surgical results, blood loss, complications. Results: We had 29 cases in the study period, all men, with average age 19,2 years, age rank 13 to 27 years. Most cases were from Lima (34%) and Cajamarca (17%). We report 90% of cases catalogued as Chandler III, 7% as Chandler IV...
