OBJECTIVE/HYPOTHESIS: The treatment of squamous cell carcinoma (SCC) of the sinonasal tract has evolved from routine exenteration of the orbital contents to sparing of the orbit when the SCC does not transgress the periorbita. Nonetheless, the influence of this change in treatment over the rate of local recurrence or survival has not been clearly elucidated. The objective was to ascertain whether orbital sparing surgery for the treatment of SCC of the paranasal sinuses influences the rate of local recurrence or survival. STUDY DESIGN: This is a retrospective study of patients presenting with SCC arising in the sinonasal tract, treated primarily at the University of Pittsburgh Medical Center from 1977 to 1990, including meta-analysis of the English literature regarding SCC of the sinonasal tract. METHODS: Review of medical records regarding demographics, histology, extension of tumor, pathologic results, type of surgery, adjunctive therapy, and outcome. Articles for meta-analysis were identified by Medline search and cross-referencing. RESULTS: Fifty-eight patients with orbital invasion, including bone and/or soft tissue invasion, were included in the study. Patients presenting with invasion of the bony orbit without soft tissue invasion were treated with maxillectomy and/or ethmoidectomy, sparing the orbital contents. Patients presenting with invasion of the orbital bones and soft tissues were treated with ethmoidectomy or maxillectomy, including orbital exenteration. At 3 years' follow-up, 52% of the patients whose orbit was exenterated were alive and without evidence of disease, compared with 59% of the patients whose orbit was spared. This difference was not statistically significant. Similarly, the rate of local recurrence was not statistically significant (P > .05). A meta-analysis of the literature revealed similar results. CONCLUSIONS: Our data suggest that sparing of the soft tissues of the orbit when the periorbita has not been transgressed by SCC does not downgrade the rate of cure or local control.
