Value of pre-operative embolization in surgery for nasopharyngeal angiofibroma
1993
The value of embolization in surgery for nasopharyngeal angiofibroma is a controversial matter. We analysed retrospectively the results of surgical treatment in ten patients with a nasopharyngeal angiofibroma, the last five of whom underwent pre-operative embolization with Gelfoam. Embolization reduced the intraoperative blood loss at primary surgery from an average of 1510 ml in the non-embolized patients to 510 ml in the embolized patients and transfusions from an average of 4.4 units to none. Seven reoperations were performed on four non-embolized patients on account of tumour recurrence, while no recurrences were diagnosed among the pre-operatively embolized patients
