Craniofacial resection for tumors of the nasal cavity and paranasal sinuses: A 25-year experience

David J. Howard FRCS, FRCS(Ed)
Abstract Background. Craniofacial resection is the established "gold standard" for surgical treatment of tumors affecting the anterior skull base. Methods. This study analyzed 308 patients (220 males, 88 females) who had undergone craniofacial resection for sinonasal neoplasia with up to 25-year follow-up. Results. An overall actuarial survival of 65% at 5 years and 47% at 10 years was found for the cohort as a whole. For patients with malignant tumors, the 5-year actuarial survival was 59%, falling to 40% at 10 years. For patients with benign pathology, the actuarial survival was 92% at 5 years falling to 82% at 10 years. Statistical analysis again identified brain involvement, type of malignancy, and orbital involvement as the 3 most significant prognostic factors. Conclusion. Analysis of one of the largest single institution cohorts over a 25-year period provides a baseline against which other approaches such as an entirely endoscopic skull base resection must be judged. © 2006 Wiley Periodicals, Inc.

Anterior skull base surgery for malignant tumors: A multivariate analysis of 27 years of experience,

Abstract Introduction. Few studies have examined prognostic factors that have an impact on outcomes in anterior skull base surgery by multivariate analysis. Methods. We retrospectively examined our institution's skull base experience from 1973,2000. Results. During this time, 166 patients underwent an anterior skull base resection for malignancy (median age, 53 years; range, 6,92 years). The 5-year relapse-free and disease-specific survival was 41% and 57% (median follow-up, 53 months). Multivariate analysis found that dural invasion, primary histologic diagnosis, and margin status had a significant impact on relapse-free and disease-specific survival. Conclusions. These data indicate that patients with anterior skull base malignancies are treated successfully with skull base surgery. Patients demonstrating adverse prognostic variables such as dural invasion, adverse histologic findings, and/or positive margins should be considered for the addition of adjuvant therapy or innovative therapies as they become available in the future. © 2003 Wiley Periodicals, Inc.

Chondrosarcoma of the Skull Base

THE LARYNGOSCOPE, Issue 1 2002
Brian Neff MD
Abstract Objectives Sarcomas of the skull base are challenging, potentially lethal tumors. Prognosis is considered poor. The present report reviews treatment options and presents a case of treatment with en bloc resection of the temporal bone and adjacent skull base. Study Design Single case report and literature review. Results Extensive skull base resection for chondrosarcoma can be performed successfully and may be curative. Conclusion There is a role for en bloc resection of large areas of the skull base for treatment of chondrosarcoma. It appears that treatment combining surgery and radiation therapy is most likely to be effective. [source]

Free tissue transfer and local flap complications in anterior and anterolateral skull base surgery

Jason A. Heth MD
Abstract Background Advances in reconstructive techniques over the past two decades have allowed the resection of more extensive skull base tumors than had previously been possible. Despite this progress, complications related to these cases remain a concern. Methods Univariate and multivariate analyses were used to determine the relationship of host, tumor, defect, treatment, and reconstructive variables to wound and systemic complications after anterior and anterolateral skull base resections. The study included 67 patients receiving local flap (LF) or free tissue transfer (FTT) reconstructions during an 8-year period. Results Overall, 28% of patients had a major wound complication, and 19% had a major systemic complication. LF and FTT flaps had similar rates of wound complications. LF reconstructions were associated with late wound breakdown problems, and FTT flap complications were primarily acute surgery,related problems. Conclusions The surgical reconstruction of skull base defects should be planned on the basis of the ability of the technique to attain safe closure and maintain integrity after radiation therapy. © 2002 Wiley Periodicals, Inc.
