Preoperative Embolization to Improve the Surgical Management and Outcome of XXXX ( @entity18871 ) in a Single Center: 10-Year Experience.

@entity1 @entity190 @entity5 @entity18871
PURPOSE: @entity18871 ( @entity18871 ) is a rare benign neoplasm that occurs almost exclusively in the nasopharynx of adolescent male individuals. METHODS: We performed a retrospective study to determine the efficacy and safety of preoperative embolization and the surgical outcome in @entity1 with @entity18871 in a single-center institution. Fifteen cases undergoing embolization and surgical treatment between April 2003 and February 2013 were evaluated retrospectively. The demographic data, clinical presentation, and treatment were reviewed including the kind of preoperative embolization and different surgical approaches performed. The parameters investigated were the amount of @entity190 , the @entity5 stage, and the rates of recurrence. Subsequently, a comparison was made between @entity1 who had undergone Onyx(  ) embolization versus those who had been embolized with the standard approach. RESULTS: In these 15 @entity1 (mean age, 15 years), a total of 27 surgical procedures were performed. One @entity1 was at stage Ia, two were at stage Ib, two were at stage IIa, six were at stage IIb, one was at stage IIc, and three were at stage IIIa based on the Radkowsky classification. All @entity1 underwent preoperative embolization and subsequent surgery. The surgical approach and the embolization technique varied and evolved during time. The embolization procedure decreased the intraoperative @entity190 to a minimum of 250  ml, and with the advent of intratumoral embolization, the rate of recurrence diminished. CONCLUSION: Preoperative Onyx(  ) embolization facilitates the shift in the treatment to endoscopic excision in selected @entity1 , which reduces recurrence rates and overall morbidity.
