Orbital invasion is a strong independent prognostic factor for sinonasal malignancies. While there is consent about preservation of the orbit for tumors limited to the orbital periosteum there is controversy about the optimal management of sinonasal malignancies transgressing this barrier. Therefore the aim of our study was to compare exenteration versus preservation of the orbit.Material and methods52 patients with sinonasal malignancies invading the orbit beyond the orbital periosteum with involvement of the orbital soft tissues were included in the retrospective study. Prognostic factors were identified through univariate analysis.ResultsUnivariate analysis revealed a significant impact of N-classification (p = 0.017), and treatment strategy (p = 0.016). Exenteration of the orbit was associated with a significantly better 5-year overall survival rate (65.5%) than preservation of the orbit (14%).ConclusionsFor patients with invasion of the structures beyond the orbital periosteum, exenteration yields better survival results than preservation of the orbital structures in combination with radiotherapy. In cases where both eyes are affected from the tumor or if only one dysfunctional eye would be left over after therapy, we do not recommend orbital exenteration because life quality would be critically deteriorated.
