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

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 10 2006
    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,

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 7 2003
    Brandon G. Bentz MD
    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.

    Preoperative risk assessment for gastrostomy tube placement in head and neck cancer patients

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 5 2001
    John M. Schweinfurth MD
    Abstract Background The presentation and definitive surgical treatment of head and neck malignancies have varying impact on postoperative recovery and return of swallowing function, which heretofore has not been well defined. Methods We performed a retrospective chart review of 142 patients who underwent extirpative surgery for head and neck cancer. Results Factors significantly associated with the need for long-term postoperative nutritional support (p < .05) included heavy alcohol use, tongue base involvement and surgery, pharyngectomy, composite resection, reconstruction with a myocutaneous flap, radiation therapy, tumor size, and moderately-to-poorly differentiated histology. Heavy alcohol users were at an absolute risk for gastrostomy tube dependence; patients who underwent radiation therapy, flap reconstruction, tongue base resection, and pharyngectomy were at a two to sevenfold increased risk for gastrostomy tube dependence, respectively. Conclusions High-risk patients based on these criteria should receive a feeding gastrostomy at the time of their initial surgical therapy. © 2001 John Wiley & Sons, Inc. Head Neck 23: 376,382, 2001.

    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]

    Anterior cranial base reconstruction using free tissue transfer: Changing trends,

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 2 2003
    Joseph Califano MD
    Abstract Introduction. A consecutive series of 135 patients undergoing resection for malignant tumors involving the anterior cranial base between 1976 and 1999 was reviewed. Patient and Methods. In the years from 1976,1991, free-tissue transfer was used in 5 of 76 or 6.6% of cases, whereas free-tissue reconstruction was used in 24 of 59 or 40% of cases in the years 1992,1999. Of those cases reconstructed with free-tissue transfer in 1976,1991, 60% (three of five) underwent a complex resection defined as involving dura, brain, or more than one major structure adjacent to skull base. Of those patients reconstructed with conventional (pericranial or pericranial/galeal) pedicled flaps in this time period, 35% (25 of 71) underwent a complex resection. From 1992,1999, 75% (18 of 24) of patients reconstructed with free-tissue transfer received a complex resection, whereas only 6% (2 of 35) of patients reconstructed by other means received a complex resection. Outcomes. For those patients reconstructed by free-tissue transfer, there were no instances of flap loss. Comparison of these two time periods was notable for a similar patient composition in terms of age, histologic findings, and extent of resection. Major complication rates for patients who are reconstructed with free-tissue transfer for anterior cranial base resections (31%) are similar compared with patients who have been reconstructed with conventional pedicled flaps (35%). This was noted despite an increased extent and complexity of resection in those patients who underwent free-tissue transfer reconstruction (72%) compared with those patients reconstructed by more conventional means (26%) p < .001. Conclusion. In our institution, the use of vascularized, free-tissue transfer has replaced pedicled flaps as the preferred modality for reconstructing complex anterior cranial base defects involving resection of dura, brain, or multiple major structures adjacent to local skull base, including the orbit, palate, and other structures. Complication rates for patients reconstructed with free-tissue transfer techniques is similar to those patients reconstructed by conventional techniques, despite an increase in complexity of resection in this group. © 2002 Wiley Periodicals, Inc.

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

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 10 2002
    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.
